NASA's RXTE Captures Thermonuclear Behavior of Unique Neutron Star
A neutron star is the closest thing to a black hole that astronomers can observe directly, crushing half a million times more mass than Earth into a sphere no larger than a city. View More (2012-03-12)
The discovery of deceleration
Pulsars are among the most exotic celestial bodies known. They have diameters of about 20 kilometres, but at the same time roughly the mass of our sun. View More (2012-02-03)

Discovery of 2 types of neutron stars points to 2 different classes of supernovae
Astronomers at the universities of Southampton and Oxford have found evidence that neutron stars, which are produced when massive stars explode as supernovae, actually come in two distinct varieties. View More (2011-11-10)
9 new gamma pulsars
Pulsars are the lighthouses of the universe. These compact and fast-rotating neutron stars flash many times per second in the radio or gamma-ray band. View More (2011-11-04)
Millisecond pulsar in spin mode
Astronomers have tracked down the first gamma-ray pulsar in a globular cluster of stars. It is around 27,000 light years away and thus also holds the distance record in this class of objects. View More (2011-11-04)

Crab Pulsar emits light at highest energies ever detected in a pulsar system, scientists report
An international team of scientists has detected the highest energy gamma rays ever observed from a pulsar, a highly magnetized and rapidly spinning neutron star. View More (2011-10-07)
Balloon-based experiment to measure gamma rays 6,500 light years distant
Beginning Sunday, September 18, 2011 at NASA's launch facility in Fort Sumner, New Mexico, space scientists from the University of New Hampshire will attempt to send a balloon up to 130,000 feet with a one-ton instrument payload to measure gamma rays from the Crab Pulsar, the remains of a supernova explosion that lies 6,500 light years from Earth.

Arachnophobes beware: Hubble snaps close-up of the Tarantula
The wispy arms of the Tarantula Nebula were originally thought to resemble spindly spider legs, giving the nebula its unusual name. View More (2011-03-15)
NASA Satellites Find High-Energy Surprises in 'Constant' Crab Nebula
The combined data from several NASA satellites has astonished astronomers by revealing unexpected changes in X-ray emission from the Crab Nebula, once thought to be the steadiest high-energy source in the sky. View More (2011-01-13)
Fermi's Large Area Telescope Sees Surprising Flares in Crab Nebula
The Crab Nebula, one of our best-known and most stable neighbors in the winter sky, is shocking scientists with its propensity for fireworks-gamma-ray flares set off by the most energetic particles ever traced to a specific astronomical object. View More (2011-01-07)
Astronomers discover most massive neutron star yet known
Astronomers using the National Science Foundation's Green Bank Telescope (GBT) have discovered the most massive neutron star yet found, a discovery with strong and wide-ranging impacts across several fields of physics and astrophysics. View More (2010-10-28)
Citizen Scientists Discover Rotating Pulsar
Idle computers are the astronomers' playground: Three citizen scientists--an American couple and a German--have discovered a new radio pulsar hidden in data gathered by the Arecibo Observatory. View More (2010-08-13)
Astronomers find cause of "dicky tickers"
In today's issue of Science, CSIRO astronomer George Hobbs and colleagues in the UK, Germany and Canada report that they have taken a big step towards solving a 30-year-old puzzle: why the "cosmic clocks" called pulsars aren't perfect. View More (2010-06-29)
Pulsars in many octaves
A unique combination of telescopes allowed astronomers to simultaneously observe the radio wavelength light from six different pulsars across wavelengths from only 3.5 centimetres up to 7 metres - a difference-factor of 200, providing an unprecedented view of how radio pulsars shine.
