The U.S. Naval Research Laboratory and the Fermi Large Area Telescope Collaboration have discovered nearly 300 gamma ray pulsars, advancing pulsar research and contributing to…
New research explores the possibility that dark matter consists of theoretical particles called axions, focusing on detecting them through additional light from pulsars. Initial observations…
Astronomers have deciphered the peculiar behavior of a pulsar, PSR J1023+0038, using 12 telescopes, including those from the European Southern Observatory (ESO). This pulsar, which…
Researchers discovered a universal scaling law in neutron stars, including magnetars, that might explain mysterious Fast Radio Bursts (FRBs). By studying the sub-structure of their…
Using the H.E.S.S. observatory in Namibia, scientists have detected exceptionally high-energy gamma rays from the Vela pulsar, challenging established theories on pulsed gamma rays from…
Artist’s illustration of a pulsar. Credit: Carl Knox, OzGrav-Swinburne University Occasionally pulsars—rapidly-spinning remnants of stars that flash like a lighthouse—show extreme variations in brightness. Astrophysicists…
A spinning neutron star periodically swings its radio (green) and gamma-ray (magenta) beams past Earth in this artist’s concept of a black widow pulsar. The…
Artist impression of the pulsar-planet system PSR B1257+12 detected in 1992. The pulsar and three radiation-doused planets are all that remains of a dead star…
The G292.0+1.8 supernova remnant contains a pulsar moving at over a million miles per hour, as seen in the Chandra image along with an optical…
As the shell of explosion debris from the supernova expands over a few decades, it becomes less dense and eventually becomes thin enough that radio…
