The gamma-ray-only pulsar lies within a supernova remnant known ... through space. Based on the remnant's age and the pulsar's distance from its center, astronomers believe the neutron ...
NASA's Chandra X-ray Observatory has provided the first clear view of the faint boundary of the Crab Nebula's X-ray-emitting pulsar wind nebula.
... has discovered 12 new gamma-ray-only pulsars and has detected gamma-ray pulses from 18 others ... Stanford University, Calif. "Now, for dozens of pulsars, we're seeing the actual power of these machines." ...
NASA's Fermi Gamma-ray Space Telescope has discovered 12 new gamma-ray-only pulsars and has detected gamma-ray pulses from 18 others. The finds are transforming our understanding of how these stellar ...
Pulsar energy, Saturn storms, and an out-of-this-world balloon are among the week's best space images.
Astronomers were recently able to combine data from telescopes across Australia to boost sensitivity – giving them the ability to test gravity theory on a pair of pulsars.

... as they radiate energy away. Radio observations of J0108 show it to be one of the oldest and faintest pulsars known, spinning only slightly faster than one revolution per second.
The surprise came ...
... distributed computing projects. More than 200,000 people have signed up for the project and donated time on their computers to search gravitational wave data for signals from unknown pulsars.
... -ray Observatory is a very young and powerful pulsar, known as PSR B1509-58, or B1509 ... pattern around this ring of emission, suggesting that the pulsar may be precessing like a spinning top and sweeping ...
... star decreased and stopped, the radio waves could emerge, and the object would be recognized as a pulsar.
This sequence of events is apparently what happened with a binary-star system some 4000 ...
Pulsars are superdense neutron stars, the remnants left after massive stars have exploded as supernovae. Their powerful magnetic fields generate lighthouse-like beams of light and radio waves that ...
Astronomers at the University of California, Santa Cruz, have developed a new technique to determine the ages of millisecond pulsars, the fastest-spinning stars in the universe.
... , the dense core left behind after a supernova explosion. Most of the 1,800 known pulsars were found through their periodic radio emissions.
"These are the first pulsars ever detected by gamma rays ...
