- Fermi Solves The Mystery Of Gamma Ray Pulsars
A pulsar is a highly magnetised rapidly spinning neutron star , the dense core remaining aftera supernova explosion.NASA's Fermi Gamma-ray Space Telescope solves the mystery of previously unidentified gamma-ray sources. Fermi has now uncovered 16...
- Cosmic Rays Accelerated By Exploded Stars
Using ESO?s Very Large Telescope and NASA?s Chandra X-ray Observatory, astronomers have shown that cosmic rays from the Milky Way are very efficiently accelerated in the remnants of exploded stars. Cosmic rays are extremely energetic particles ? mostly...
- Oldest Isolated Pulsar Ever Found By X-rays
The oldest isolated pulsar ever detected in X-rays has been found with NASA's Chandra X-ray Observatory. This very old and exotic object is surprisingly active.The pulsar is about 200 million years old....
- White Dwarfs As Pulsars
A little more than two years ago, in early 2008, there was a shocking discovery from the Suzaku team. Suzaku is an orbiting X-ray observatory, operated jointly by JAXA and NASA. It had detected a white dwarf star, AE Aquarii, emit high-energy X-ray pulses....
- Star Got Swallowed By A Warp In Space.
A star has slipped out of view of astronomers due to the space-time warp. The disappearing star is part of a binary star system called J1906. It's a pulsar, which means it's a rotating neutron star, the result of a massive star collapsing in...

Young pulsar shows its hand
small, dense object only twelve miles in diameter is responsible for this beautiful X-ray nebula that spans 150 light years. At the center of this image made by NASA's Chandra X-ray Observatory is a very young and powerful pulsar, known as PSR B1509-58, or B1509 for short. The pulsar is a rapidly spinning neutron star which is spewing energy out into the space around it to create complex and intriguing structures, including one that resembles a large cosmic hand. In this image, the lowest energy X-rays that Chandra detects are red, the medium range is green, and the most energetic ones are colored blue. Astronomers think that B1509 is about 1,700 years old and is located about 17,000 light years away.
