Astronomers Discover Youngest Black Hole In Milky Way
2013-02-13 12:11:40

Astronomers using NASA's Chandra X-ray Observatory claim that matter was ejected at high speeds along the poles of a rotating star, creating a supernova remnant, W49B, which may contain a young black hole.

New Chandra Footage Suggests Vela Pulsar May Be Precessing
2013-01-08 12:30:00

New video footage of the Vela pulsar, a neutron star located approximately 1,000 light-years from Earth, suggests that the pulsar could be slowly wobbling as it spins, NASA officials said on Monday.

Researchers Disprove Pulsar Glitch Theory
2012-12-18 16:21:44

Researchers reported in the journal Physical Review Letters that they have found a "glitch" in a 40-year-old theory explaining the periodic speeding up or "glitching" of pulsars.

Supernova Remnant Reveals Its Aftershock
2012-11-14 12:57:25

A new image released by the European Space Agency shows the aftershock of a stellar explosion coming from supernova remnant W44.

Pulsar Speed And Rotation Explained By New Model
2012-10-09 14:38:04

A new model developed by researchers at the University of Southampton explains how the spin of a pulsar slows down as the star gets older.

Chandra Finds Young Supernova Remnant Spitting Out X-rays
2012-07-31 05:18:12

In a galaxy not that far away, astronomically speaking at least, researchers using NASA's Chandra X-ray Observatory have detected the first x-rays emitted by the debris of a young supernova, SN 1957D.

Astronomers Locate Gamma-ray Pulsar With The Hiccups
2012-07-24 11:51:53

A special gamma-ray pulsar with the hiccups has been discovered by researchers from the Max Planck Institutes for Gravitational Physics and Radio Astronomy (MPIfR) using data constructed from the Fermi Gamma-ray Space Telescope.

Split Personality Star Discovered
2012-07-16 14:42:45

One recently discovered star seems to have a split personality, with both a magnetar and pulsar consuming the object.

Chandra Captures Supernova Shock Wave
2012-05-16 03:13:51

Observations with NASA's Chandra X-ray Observatory have provided the first X-ray evidence of a supernova shock wave breaking through a cocoon of gas surrounding the star that exploded.

X-Ray Astronomy -- Although the more energetic X-rays (E > 30 keV) can penetrate the air at least for distances of a few meters (they would never have been detected and medical X-ray machines would not work if this was not the case) the Earth's atmosphere is thick enough that virtually none are able to penetrate from outer space all the way to the Earth's surface. X-rays in the 0.5 - 5 keV range, where most celestial sources give off the bulk of their energy, can be stopped by a few...

X-ray Pulsar -- This dramatic artist's vision shows a city-sized neutron star centered in a disk of hot plasma drawn from its enfeebled red companion star. Ravenously accreting material from the disk, the neutron star spins faster and faster emitting powerful particle beams and pulses of X-rays as it rotates 400 times a second. Could such a bizarre and inhospitable star system really exist in our Universe? Based on data from the orbiting Rossi X-Ray Timing Explorer (RXTE) satellite,...

Supernova
2004-10-19 04:45:42

Supernova -- A supernova is a star that increases its brightness drastically within a matter of days, making it appear as if a "new" star was born (hence "nova"). The "super" prefix distinguishes it from a mere nova, which also involves a star increasing in brightness, though to a lesser extent and through a much different mechanism. Astronomers have classified supernovae in several classes, according to the lines of different elements that appear in their spectra. The first element...

Strange Matter -- Strange matter (also known as quark matter) is an ultra-dense phase of matter that is theorized to form inside particularly massive neutron stars (which are then known as "strange stars" or "quark stars"). It's theorized that when neutronium is put under sufficient pressure due to the gravitation of a large neutron star, the individual neutrons break down and their constituent quarks form strange matter. Strange matter is composed of strange quarks bound to each...

Pulsar -- A pulsar, which originally stood for pulsating radio source, is a rapidly rotating neutron star, whose electromagnetic radiation is observed in regularly spaced interval, or pulses. Pulsars are closely related to magnetars, the main difference being the strenght of the object's magnetic field. History Pulsars were discovered by Jocelyn Bell and Antony Hewish in 1967 while they were using a radio array to study the scintillation of quasars. They found a very regular...
