I watched a documentary the other day about Pulsars, and the Hubble Telescope showed images of pulsars spinning and then let us hear the beats and sounds of different kinds that they made that nobody in space can hear, but our technology can listen in on.  It was just phenomenal.

Then I found out that there was a star music festival in Tenerife last July, and here is a little something from that.

The spinning star, a millisecond pulsar called J1823-3021A, is located inside a packed conglomeration of stars called a globular cluster about 27,000 light-years from Earth in the constellation Sagittarius.

The pulsar emits incredibly intense high-energy gamma rays, which the researchers detected and studied using NASA's Fermi Gamma-Ray Space Telescope. Their analysis suggests the pulsar is just 25 million years old — a baby as far as these stars go, for millisecond pulsars tend to be a billion years old or so, researchers said.

The pulsar's extreme brightness and youth challenge current ideas about how super-bright millisecond pulsars form and how widespread they may be, researchers said. [Top 10 Strangest Things in Space]

Astronomers Discover Fastest-Spinning Pulsar

Graphics: How Are Millisecond Pulsars Formed?

Astronomers using the National Science Foundation's Robert C. Byrd Green Bank Telescope have discovered the fastest-spinning neutron star ever found, a 20-mile-diameter superdense pulsar whirling faster than the blades of a kitchen blender. Their work yields important new information about the nature of one of the most exotic forms of matter known in the Universe.

"We believe that the matter in neutron stars is denser than an atomic nucleus, but it is unclear by how much. Our observations of such a rapidly rotating star set a hard upper limit on its size, and hence on how dense the star can be.," said Jason Hessels, a graduate student at McGill University in Montreal. Hessels and his colleagues presented their findings to the American Astronomical Society's meeting in Washington, DC.

Pulsars are spinning neutron stars that sling "lighthouse beams" of radio waves or light around as they spin. A neutron star is what is left after a massive star explodes at the end of its "normal" life. With no nuclear fuel left to produce energy to offset the stellar remnant's weight, its material is compressed to extreme densities. The pressure squeezes together most of its protons and electrons to form neutrons; hence, the name "neutron star."

"Neutron stars are incredible laboratories for learning about the physics of the fundamental particles of nature, and this pulsar has given us an important new limit," explained Scott Ransom, an astronomer at the National Radio Astronomy Observatory and one of Hessels' collaborators on this work.

The scientists discovered the pulsar, named PSR J1748-2446ad, in a globular cluster of stars called Terzan 5, located some 28,000 light-years from Earth in the constellation Sagittarius. The newly-discovered pulsar is spinning 716 times per second, or at 716 Hertz (Hz), readily beating the previous record of 642 Hz from a pulsar discovered in 1982. For reference, the fastest speeds of common kitchen blenders are 250-500 Hz.

The scientists say the object's fast rotation speed means that it cannot be any larger than about 20 miles across. According to Hessels, "If it were any larger, material from the surface would be flung into orbit around the star." The scientists' calculation assumed that the neutron star contains less than two times the mass of the Sun, an assumption that is consistent with the masses of all known neutron stars.

The spinning pulsar has a companion star that orbits it once every 26 hours. The companion passes in front of the pulsar, eclipsing the pulsar about 40 percent of the time. The long eclipse period, probably due to bloating of the companion, makes it difficult for the astronomers to learn details of the orbital configuration that would allow them to precisely measure the masses of the pulsar and its companion.

"If we could pin down these masses more precisely, we could then get a better limit on the size of the pulsar. That, in turn, would then give us a better figure for the true density inside the neutron star," explained Ingrid Stairs, an assistant professor at the University of British Columbia and another collaborator on the work.

Competing theoretical models for the types and distributions of elementary particles inside neutron stars make widely different predictions about the pressure and density of such an object.

"We want observational data that shows which models fit the reality of nature," Hessels said.

If the scientists can't use PSR J1748-2446ad to do that, they are hopeful some of its near neighbors will yield the data they seek. Using the GBT, the astronomers so far have found 30 new fast "millisecond pulsars" in the cluster Terzan 5, making 33 pulsars known in the cluster in total. This is the largest number of such pulsars ever found in a single globular cluster.

Dense globular clusters of stars are excellent places to find fast-rotating millisecond pulsars. Giant stars explode as supernovae and leave rotating pulsars which gradually slow down. However, if a pulsar has a companion star from which it can draw material, that incoming material imparts its spin, or angular momentum, to the pulsar. As a result, the pulsar spins faster. "In a dense cluster, interactions between the stars will create more binary pairs that can yield more fast-rotating pulsars," Ransom said.

The great sensitivity of the giant, 100-meter diameter GBT, along with a special signal processor, called the Pulsar Spigot, made possible the discovery of so many millisecond pulsars in Terzan 5. "We think there are many more pulsars to be found in Terzan 5 and other clusters, and given that the fast ones are often hidden by eclipses, some of them may be spinning even faster than this new one," Ransom said

"We're excited about using this outstanding new telescope to answer some important questions about fundamental physics," he said.

In addition to Hessels, Ransom and Stairs, the research team includes Paulo Freire of Arecibo Observatory in Puerto Rico, Victoria Kaspi, of McGill University, and Fernando Camilo, of Columbia University. Their report is being published in Science Express, the online version of the journal Science.

The National Radio Astronomy Observatory is a facility of the National Science Foundation, operated under cooperative agreement by Associated Universities, Inc. The pulsar research also was supported by the Canada Foundation for Innovation, the Natural Sciences and Engineering Research Council of Canada, the Quebec Foundation for Research on Nature and Technology, the Canadian Institute for Advanced Research, the Canada Research Chairs Program, and the National Science Foundation..

The Sounds of Pulsars


What is a pulsar?

A pulsar is a highly magnetised neutron star, with a radius of 10-15 km, having somewhat greater mass than the Sun which has a radius of approximately 1 million km. Radiation is beamed out along the magnetic poles and pulses of radiation are received as the beam crosses the Earth, in the same manner as the beam from a lighthouse causes flashes. Being enormous cosmic flywheels with a tick attached, they make some of the best clocks known to mankind.

These sounds directly correspond to the radio-waves emitted by the brightest pulsars in the sky as received by some of the largest radio telescopes in the world. To listen to the pulses of a radio pulsar, click on its arrow icon.

PSR B0329+54

This pulsar is a typical, normal pulsar, rotating with a period of 0.714519 seconds, i.e. close to 1.40 rotations/sec.

THIS IS THE SOUND   http://www.jb.man.ac.uk/~pulsar/Education/Sounds/B0329.au 


PSR B0833-45, The Vela Pulsar

This pulsar lies near the centre of the Vela supernova remnant, which is the debris of the explosion of a massive star about 10,000 years ago. The pulsar is the collapsed core of this star, rotating with a period of 89 milliseconds or about 11 times a second.

THIS IS THE SOUND:  http://www.jb.man.ac.uk/~pulsar/Education/Sounds/vela.au


PSR B0531+21, The Crab Pulsar

This is the youngest known pulsar and lies at the centre of the Crab Nebula, the supernova remnant of its birth explosion, which was witnessed by Europeans and Chinese in the year 1054 A.D. as a day-time light in the sky. The pulsar rotates about 30 times a second.

here is the sound:  http://www.jb.man.ac.uk/~pulsar/Education/Sounds/crab.au


PSR J0437-4715

This is a recently discovered millisecond pulsar, an old pulsar which has been spun up by the accretion of material from a binary companion star as it expands in its red giant phase. The accretion process results in orbital angular momentum of the companion star being converted to rotational angular momentum of the neutron star, which is now rotating about 174 times a second.

HERE IS THE SOUND:  http://www.jb.man.ac.uk/~pulsar/Education/Sounds/J0437.au



PSR B1937+21

This is the second fastest known pulsar, rotating with a period of 0.00155780644887275 seconds, or about 642 times a second. The surface of this star is moving at about 1/7 of the velocity of light and illustrates the enormous gravitational forces which prevent it flying apart due to the immense centrifugal forces. The fastest-rotating pulsar is PSR J1748-2446ad, which rotates about 10% faster at 716 times a second.

A pulsar (portmanteau of pulsating star) is a highly magnetized, rotating neutron star that emits a beam of electromagnetic radiation. The radiation can only be observed when the beam of emission is pointing towards the Earth, much the way a lighthouse can only be seen when the light is pointed in the direction of an observer, and is responsible for the pulsed appearance of emission. Neutron stars are very dense, and have short, regular rotational periods. This produces a very precise interval between pulses that ranges from roughly milliseconds to seconds for an individual pulsars.

The precise periods of pulsars makes them useful tools. Observations of a pulsar in a binary neutron star system were used to confirm the existence of gravitational radiation. The first extrasolar planets were discovered around a pulsar, PSR B1257+12. Certain types of pulsars rival atomic clocks in their accuracy in keeping time

The first pulsar was observed on November 28, 1967 by Jocelyn Bell Burnell and Antony Hewish.[1][2][3] The observed emission from the pulsar was pulses separated by 1.33 seconds, originated from the same location on the sky, and kept to sidereal time. In looking for explanations for the pulses, the short period of the pulses eliminated most astrophysical sources of radiation, such as stars, and since the pulses followed sidereal time, it could not be man-made radio frequency interference. When observations with another telescope confirmed the emission, it eliminated any sort of instrumental effects. At this point, Burnell notes of herself and Hewish that "we did not really believe that we had picked up signals from another civilization, but obviously the idea had crossed our minds and we had no proof that it was an entirely natural radio emission. It is an interesting problem—if one thinks one may have detected life elsewhere in the universe, how does one announce the results responsibly?"[4] Even so, they nicknamed the signal LGM-1, for "little green men" (a name for intelligent beings of extraterrestrial origin). It was not until a second pulsating source was discovered in a different part of the sky that the "LGM hypothesis" was entirely abandoned.[5] Their pulsar was later dubbed CP 1919, and is now known by a number of designators including PSR 1919+21, PSR B1919+21 and PSR J1921+2153. Although CP 1919 emits in radio wavelengths, pulsars have, subsequently, been found to emit in visible light, X-ray, and/or gamma ray wavelengths.[6]

The word "pulsar" is a contraction of "pulsating star",[7] and first appeared in print in 1968:

An entirely novel kind of star came to light on Aug. 6 last year and was referred to, by astronomers, as LGM (Little Green Men). Now it is thought to be a novel type between a white dwarf and a neutron [sic]. The name Pulsar is likely to be given to it. Dr. A. Hewish told me yesterday: "… I am sure that today every radio telescope is looking at the Pulsars."[8]

The suggestion that pulsars were rotating neutron stars was put forth independently by Thomas Gold and Franco Pacini in 1968, and was soon proven beyond reasonable doubt by the discovery of a pulsar with a very short (33-millisecond) pulse period in the Crab nebula.

In 1974, Antony Hewish became the first astronomer to be awarded the Nobel Prize in physics. Considerable controversy is associated with the fact that Professor Hewish was awarded the prize while Bell, who made the initial discovery while she was his Ph.D student, was not. Bell claims no bitterness upon this point, supporting the decision of the Nobel prize committee.[9]


The Vela Pulsar and its surrounding pulsar wind nebula.

In 1974, Joseph Hooton Taylor, Jr. and Russell Hulse discovered for the first time a pulsar in a binary system, PSR B1913+16. This pulsar orbits another neutron star with an orbital period of just eight hours. Einstein's theory of general relativity predicts that this system should emit strong gravitational radiation, causing the orbit to continually contract as it loses orbital energy. Observations of the pulsar soon confirmed this prediction, providing the first ever evidence of the existence of gravitational waves. As of 2004, observations of this pulsar continue to agree with general relativity. In 1993, the Nobel Prize in Physics was awarded to Taylor and Hulse for the discovery of this pulsar.[10]

In 1982, Don Backer led a group which discovered PSR B1937+21, a pulsar with a rotation period of just 1.6 milliseconds.[11] Observations soon revealed that its magnetic field was much weaker than ordinary pulsars, while further discoveries cemented the idea that a new class of object, the "millisecond pulsars" (MSPs) had been found. MSPs are believed to be the end product of X-ray binaries. Owing to their extraordinarily rapid and stable rotation, MSPs can be used by astronomers as clocks rivaling the stability of the best atomic clocks on Earth. Factors affecting the arrival time of pulses at the Earth by more than a few hundred nanoseconds can be easily detected and used to make precise measurements. Physical parameters accessible through pulsar timing include the 3D position of the pulsar, its proper motion, the electron content of the interstellar medium along the propagation path, the orbital parameters of any binary companion, the pulsar rotation period and its evolution with time. (These are computed from the raw timing data by Tempo, a computer program specialized for this task.) After these factors have been taken into account, deviations between the observed arrival times and predictions made using these parameters can be found and attributed to one of three possibilities: intrinsic variations in the spin period of the pulsar, errors in the realization of Terrestrial Time against which arrival times were measured, or the presence of background gravitational waves. Scientists are currently attempting to resolve these possibilities by comparing the deviations seen amongst several different pulsars, forming what is known as a Pulsar timing array. With luck, these efforts may lead to a time scale a factor of ten or better than currently available, and the first ever direct detection of gravitational waves. In June 2006, the astronomer John Middleditch and his team at LANL announced the first prediction of pulsar glitches with observational data from the Rossi X-ray Timing Explorer. They used observations of the pulsar PSR J0537-6910.

In 1992, Aleksander Wolszczan discovered the first extrasolar planets around PSR B1257+12. This discovery presented important evidence concerning the widespread existence of planets outside the solar system, although it is very unlikely that any life form could survive in the environment of intense radiation near a pulsar.

[edit] Nomenclature

Initially pulsars were named with letters of the discovering observatory followed by their right ascension (e.g. CP 1919). As more pulsars were discovered, the letter code became unwieldy and so the convention was then superseded by the letters PSR (Pulsating Source of Radio) followed by the pulsar's right ascension and degrees of declination (e.g. PSR 0531+21) and sometimes declination to a tenth of a degree (e.g. PSR 1913+167). Pulsars that are very close together sometimes have letters appended (e.g. PSR 0021-72C and PSR 0021-72D).

The modern convention is to prefix the older numbers with a B (e.g. PSR B1919+21) with the B meaning the coordinates are for the 1950.0 epoch. All new pulsars have a J indicating 2000.0 coordinates and also have declination including minutes (e.g. PSR J1921+2153). Pulsars that were discovered before 1993 tend to retain their B names rather than use their J names (e.g. PSR J1921+2153 is more commonly known as PSR B1919+21). Recently discovered pulsars only have a J name (e.g. PSR J0437-4715). All pulsars have a J name that provides more precise coordinates of its location in the sky.[12]


Schematic view of a pulsar. The sphere in the middle represents the neutron star, the curves indicate the magnetic field lines, the protruding cones represent the emission beams and the green line represents the axis on which the star rotates.

The events leading to the formation of a pulsar begin when the core of a massive star is compressed during a supernova, which collapses into a neutron star. The neutron star retains most of its angular momentum, and since it has only a tiny fraction of its progenitor's radius (and therefore its moment of inertia is sharply reduced), it is formed with very high rotation speed. A beam of radiation is emitted along the magnetic axis of the pulsar, which spins along with the rotation of the neutron star. The magnetic axis of the pulsar determines the direction of the electromagnetic beam, with the magnetic axis not necessarily being the same as its rotational axis. This misalignment causes the beam to be seen once for every rotation of the neutron star, which leads to the "pulsed" nature of its appearance. The beam originates from the rotational energy of the neutron star, which generates an electrical field from the movement of the very strong magnetic field, resulting in the acceleration of protons and electrons on the star surface and the creation of an electromagnetic beam emanating from the poles of the magnetic field.[13][14] This rotation slows down over time as electromagnetic power is emitted. When a pulsar's spin period slows down sufficiently, the radio pulsar mechanism is believed to turn off (the so-called "death line"). This turn-off seems to take place after about 10–100 million years, which means of all the neutron stars in the 13.6 billion year age of the universe, around 99% no longer pulsate.[15] The longest known pulsar period is 8.5 seconds.[16]

Though this very general picture of pulsars is mostly accepted, Werner Becker of the Max Planck Institute for Extraterrestrial Physics said in 2006, "The theory of how pulsars emit their radiation is still in its infancy, even after nearly forty years of work."[17]

[edit] Categories

Three distinct classes of pulsars are currently known to astronomers, according to the source of the power of the electromagnetic radiation:

The Fermi Space Telescope has uncovered a subclass of rotationally-powered pulsars that emit only gamma rays.[18] There have been only about one hundred gamma-ray pulsars identified out of about 1800 known pulsars.[19][20]

Although all three classes of objects are neutron stars, their observable behavior and the underlying physics are quite different. There are, however, connections. For example, X-ray pulsars are probably old rotationally-powered pulsars that have already lost most of their power, and have only become visible again after their binary companions had expanded and began transferring matter on to the neutron star. The process of accretion can in turn transfer enough angular momentum to the neutron star to "recycle" it as a rotation-powered millisecond pulsar. As this matter lands on the neutron star, it is thought to "bury" the magnetic field of the neutron star (although the details are unclear), leaving millisecond pulsars with magnetic fields 1000-10,000 times weaker than average pulsars. This low magnetic field is less effective at slowing the pulsar's rotation, so millisecond pulsars live for billions of years, making them the oldest known pulsars. Millisecond pulsars are seen in globular clusters, which stopped forming neutron stars billions of years ago.[15]

Of interest to the study of the state of the matter in a neutron stars are the glitches observed in the rotation velocity of the neutron star. This velocity is decreasing slowly but steadily, except by sudden variations. One model put forward to explain these glitches is that they are the result of "starquakes" that adjust the crust of the neutron star. Models where the glitch is due to a decoupling of the possibly superconducting interior of the star have also been advanced. In both cases, the star's moment of inertia changes, but its angular momentum doesn't, resulting in a change in rotation rate.

[edit] Disrupted recycled pulsar

When two massive stars are born close together from the same cloud of gas, they can form a binary system and orbit each other from birth. If those two stars are at least a few times as massive as our sun, their lives will both end in supernova explosions. The more massive star explodes first, leaving behind a neutron star. If the explosion does not kick the second star away, the binary system survives. The neutron star can now be visible as a radio pulsar, and it slowly loses energy and spins down. Later, the second star can swell up, allowing the neutron star to suck up its matter. The matter falling onto the neutron star spins it up and reduces its magnetic field. This is called “recycling” because it returns the neutron star to a quickly-spinning state. Finally, the second star also explodes in a supernova, producing another neutron star. If this second explosion also fails to disrupt the binary, a double neutron star binary is formed. Otherwise, the spun-up neutron star is left with no companion and becomes a “disrupted recycled pulsar”, spinning between a few and 50 times per second.[21]

[edit] PIOMEER PLAQUEApplications Relative position of the Sun to the center of the Galaxy and 14 pulsars with their periods denoted

The study of pulsars has resulted in many applications in physics and astronomy. Striking examples include the confirmation of the existence of gravitational radiation as predicted by general relativity and the first detection of an extrasolar planetary system.

The discovery of pulsars allowed astronomers to study an object never observed before, the neutron star. This kind of object is the only place where the behavior of matter at nuclear density can be observed (though not directly). Also, millisecond pulsars have allowed a test of general relativity in conditions of an intense gravitational field.

Pulsar maps have been included on the two Pioneer Plaques as well as the Voyager Golden Record. They show the position of the Sun, relative to 14 pulsars, which are identified by the unique timing of their electromagnetic pulses, so that our position both in space and in time can be calculated by potential extraterrestrial intelligences.[22][23] Because pulsars are emitting very regular pulses of radio waves, its radio transmissions do not require daily corrections. Moreover, pulsar positioning could create a spacecraft navigation system independently, or be an auxiliary device to GPS instruments.[24][25]

[edit] Precise clocks

For some millisecond pulsars, the regularity of pulsation is as precise as an atomic clock.[26] This stability allows millisecond pulsars to be used in establishing ephemeris time.[27]

[edit] Probes of the interstellar medium

The radiation from pulsars passes through the interstellar medium (ISM) before reaching Earth. Free electrons in the warm (8000 K), ionized component of the ISM and H II regions affect the radiation in two primary ways. The resulting changes to the pulsar's radiation provide an important probe of the ISM itself.[28]

Because of the dispersive nature of the interstellar plasma, lower-frequency radio waves travel through the medium slower than higher-frequency radio waves. The resulting delay in the arrival of pulses at a range of frequencies is directly measurable as the dispersion measure of the pulsar. The dispersion measure is the total column density of free electrons between the observer and the pulsar,

where D is the distance from the pulsar to the observer and ne is the electron density of the ISM. The dispersion measure is used to construct models of the free electron distribution in the Milky Way Galaxy.[29]

Additionally, turbulence in the interstellar gas causes density inhomogeneities in the ISM which cause scattering of the radio waves from the pulsar. The resulting scintillation of the radio waves—the same effect as the twinkling of a star in visible light due to density variations in the Earth's atmosphere—can be used to reconstruct information about the small scale variations in the ISM.[30] Due to the high velocity (up to several hundred km/s) of many pulsars, a single pulsar scans the ISM rapidly, which results in changing scintillation patterns over timescales of a few minutes.[31]

[edit] Probes of space-time

Pulsars orbiting within the curved space-time around Sgr A*, the supermassive black hole at the center of the Milky Way galaxy, could serve as probes of gravity in the strong-field regime.[32] Arrival times of the pulses would be affected by special- and general-relativistic Doppler shifts and by the complicated paths that the radio waves would travel through the strongly curved space-time around the black hole. In order for the effects of general relativity to be measurable with current instruments, pulsars with orbital periods less than about 10 years would need to be discovered;[32] such pulsars would orbit at distances inside 0.01 pc from Sgr A*. Searches are currently underway; at present, five pulsars are known to lie within 100 pc from Gamma-ray pulsars detected by the Fermi Gamma-ray Space Telescope.




Crab Pulsar Dazzles Astronomers With Its Gamma-Ray Beams

ScienceDaily (Oct. 6, 2011) — A thousand years ago, a brilliant beacon of light blazed in the sky, shining brightly enough to be seen even in daytime for almost a month. Native American and Chinese observers recorded the eye-catching event. We now know that they witnessed an exploding star, which left behind a gaseous remnant known as the Crab Nebula.


The same object that dazzled skygazers in 1054 C.E. continues to dazzle astronomers today by pumping out radiation at higher energies than anyone expected. Researchers have detected pulses of gamma rays with energies exceeding 100 billion electron-volts (100 GeV) -- a million times more energetic than medical X-rays and 100 billion times more than visible light.

"If you asked theorists a year ago whether we would see gamma-ray pulses this energetic, almost all of them would have said, 'No.' There's just no theory that can account for what we've found," said corresponding author Martin Schroedter of the Harvard-Smithsonian Center for Astrophysics (CfA).

The gamma rays come from an extreme object at the Crab Nebula's center known as a pulsar. A pulsar is a spinning neutron star -- the collapsed core of a massive star. Although only a few miles across, a neutron star is so dense that it weighs more than the Sun.


Rotating about 30 times a second, the Crab pulsar generates beams of radiation from its spinning magnetic field. The beams sweep around like a lighthouse beacon because they're not aligned with the star's rotation axis. So although the beams are steady, they're detected on Earth as rapid pulses of radiation.


The discovery was reported by an international team of scientists in a paper in the October 7 issue of Science. Corresponding author Nepomuk Otte, a postdoctoral researcher at the University of California, Santa Cruz, said that some researchers had told him he was crazy to even look for pulsar emission in this energy realm.


"It turns out that being persistent and stubborn helps," Otte said. "These results put new constraints on the mechanism for how the gamma-ray emission is generated."


Some possible scenarios to explain the data have been put forward, but it will take more data, or even a next-generation observatory, to really understand the mechanisms behind these gamma-ray pulses.


The gamma-ray pulses were detected by the Very Energetic Radiation Imaging Telescope Array System (VERITAS) -- the most powerful very-high-energy gamma-ray observatory in the Northern Hemisphere. VERITAS is located at the Smithsonian's Whipple Observatory, just south of Tucson, Ariz.

Astronomers observe very-high-energy gamma rays with ground-based Cherenkov telescopes. These gamma rays, coming from cosmic "particle accelerators," are absorbed in Earth's atmosphere, where they create a short-lived shower of subatomic particles. The Cherenkov telescopes detect the faint, extremely short flashes of blue light that these particles emit (named Cherenkov light) using extremely sensitive cameras. The images can be used to infer the arrival direction and initial energy of the gamma rays.


This technique is used by gamma-ray observatories throughout the world, and was pioneered under the direction of CfA's Trevor Weekes using the 10-meter Cherenkov telescope at Whipple Observatory. The Whipple 10-meter telescope was used to detect the first Galactic and extragalactic sources of very-high-energy gamma rays.


VERITAS continues the tradition of Whipple's 10-meter telescope. It is composed of an array of four 12-meter-diameter Cherenkov telescopes. VERITAS began full-scale observations in September 2007. The telescopes are used to study the remnants of exploded stars, distant galaxies, powerful gamma-ray bursts, and to search for evidence of mysterious dark matter particles.

Brian May - musician, songwriter and astronomer - was installed as the fourth Chancellor of Liverpool John Moores University.



The installation ceremony took place in Liverpool's St George's Hall on 14 April in front of an audience of some 500 staff, students and alumni of the University as well as the Lord Lieutenant of Liverpool, mayors and other dignitaries.


Two former LJMU Chancellors were also in attendance - Cherie Booth QC, who served as Chancellor between 1999 and 2006, and John Moores CBE, her predecessor, who served from 1994 to 1999.


Professor Michael Brown CBE, LJMU's Vice-Chancellor, said:

"The ethos of this University is summed up in three simple words: Dream, Plan, Achieve. No one embodies this more perfectly than our new Chancellor, Dr Brian May. While gaining global recognition as a musician, and supporter of the performing arts, he never lost sight of his dream, his passion for astronomy and science. Thirty years after starting his PhD, he achieved his doctorate, proving himself a true polymath and exemplifying the power of lifelong learning.

"Such dedication and commitment are echoed in the determined efforts of LJMU's staff and students as work towards their goals. There is no doubt that Brian May will be a real champion for LJMU and a tremendous role model for our students. We are delighted to welcome him as our new Chancellor today."

Chancellor Dr Brian May responded, saying:


"I am very proud to be the new Chancellor of Liverpool John Moores University, and I am particularly touched that so many staff and students are able to be here today. I am passionate about education and lifelong learning. It really doesn't matter how old you are or what stage of your life you are in, it is never, ever too late to start learning. I proved that by completing my PhD, 30 years after I started it. As Chancellor, I hope that my personal experiences will act as an inspiration for others."


Brian May's involvement with the University began in 2007 when he was awarded an Honorary Fellow in recognition of his outstanding contribution to the arts, but more significantly for encouraging the public understanding of science following publication of his renowned book Bang! The Complete History of the Universe. Dr May co-authored the book with Chris Lintott and Sir Patrick Moore, who is also a Fellow of LJMU.

Brian studied Astrophysics at Imperial College, London and gained his BSc before progressing to a PhD. He put his academic career on hold to concentrate on his musical ambitions, founding the rock group Queen, which has since enjoyed world-wide success selling 400 million records and touring the world many times. In October 2007, he finally completed his PhD thesis and was awarded his doctorate.


Dr May has already established links with scientists in the University's internationally acclaimed Astrophysics Research Institute, whose world-class research, work with schoolchildren, and development of robotic telescopes earned them a Queen's Anniversary Prize in 2005.


Fittingly, the University-owned Liverpool Telescope - one of the world's largest robotic telescopes, designed and built by LJMU experts - is located in La Palma, Canaries, the location of Dr May's original observations when a PhD student at Imperial.


Professor Mike Bode, Director of LJMU's Astrophysics Research Institute said:

This unique conference, accompanied by musical performances, will take us to an amazing journay in time, highlighting the most dramatic and important moments in space exploration during the last 50 years.

We provide simultaneous interpretation into English, Spanish, Russian and French for all the speeches!

Alexei Leonov

Russian Cosmonaut

On 18 March, 1965, Alexey Leonov became the first human to conduct a space walk. This historic event occurred on the Voskhod 2 flight. He was outside the spacecraft for 12 minutes and nine seconds on 18 March, 1965, connected to the craft by a 5.35 metre tether. At the end of the spacewalk, Leonov’s spacesuit had inflated in the vacuum of space to the point where he could not re-enter the airlock. He opened a valve to allow some of the suit’s pressure to bleed off and was barely able to get back inside the capsule. From 1976 to 1982, Leonov was the commander of the cosmonaut team (“Chief Cosmonaut”) and deputy director of the Yuri Gagarin Cosmonaut Training Center. Leonov is an accomplished artist whose published books include albums of his artistic works. Arthur C. Clarke’s book 2010: Odyssey Two was dedicated Leonov and Andrei Sakharov; the fictional spaceship Cosmonaut Alexei Leonov was named after him.

Tangerine Dream

Special guest: Brian May

Buy tickets

Tangerine Dream, this seven time Grammy nominated European band, is a singular phenomenon. They are using just high-end modern technology for their unusual instrumental compositions and live performances. Many have tried to copy

the band of Edgar Froese, the creative head and founder of TD, what‘s become known as "The Tangerine Dream Sound"- so far absolutely unsuccessfully.

Even to describe what their music is all about can be a hard job - TD will hardly fit into any given musical pigeonhole. Recognizing the here today, gone tomorrow adage of the entertainment industry, TD has robustly survived all the stormy and cloudy days within the international showbiz.

Apart from their outstanding live performances around the globe and their high profile studio work, the Hollywood business has played a major role within TD‘s international career. For many years TD did lots of haunting scores for Hollywood movie productions. At a time when electronic instruments were widely misunderstood, Tangerine Dream became recognized as the pioneers of a new instrumental music in the USA. They introduced new sounds, sound effects and so far unknown production techniques.

They do not belong to any idea of nationalism or homebound philosophies - they are real cosmopolitan travellers, respecting this planet earth as their artistic basis.

Great painters, photographers, actors, writers and dancers have honoured Tangerine Dream for the inspiration for their own work they got from listening to the music of TD. Tangerine Dream’s reputation in the world of music, their vast experience and professionalism has reserved them already a place within the gallery of remarkable artists out of the last four decades.
