Why Have Pulsars “Gone Missing” – A New Finding Offers Some Answers
New finding offers clues to “missing” pulsars. MSPs, or millisecond pulsars, are evolved neutron stars with brief spin periods that underwent extensive mass transfer during…

Occasionally pulsars—rapidly-spinning remnants of stars that flash like a lighthouse—show extreme variations in brightness. Astrophysicists predict that these short bursts of brightness occur because dense…
Observations of faint, planet-size star help weigh its millisecond pulsar companion. A dense, collapsed star has shredded and consumed nearly the entire mass of its…
30 years ago, the first-ever exoplanets were discovered around a rapidly rotating star, called a pulsar. Now, astronomers have revealed that these planets may be…
A young pulsar has been discovered blazing through the Milky Way at a speed of over a million miles per hour. This stellar speedster, witnessed…
Astronomers analyzing data from the VLA Sky Survey (VLASS) have discovered one of the youngest known neutron stars — the superdense remnant of a massive…
A pulsar is racing through the debris of an exploded star at a speed of over a million miles per hour. To measure this, researchers…
When a massive star runs out of fuel and collapses, it may leave behind a neutron star. (Unless the leftover mass is too great, in…
The system, which may have originated near the center of the Milky Way, is orbited by a third stellar companion. The flashing of a nearby…
Researchers from The Australian National University (ANU) have found an alternative explanation for a mysterious gamma-ray signal coming from the center of the galaxy, which…
The High Time Resolution Universe Pulsar Survey Double neutron star (DNS) systems in tight orbits are fantastic laboratories to test Einstein’s general theory of relativity….
NASA’s FERMI Satellite Hunts for Extremely Long-wavelength Gravitational-Wave Signals Coalescing supermassive black holes in the centers of merging galaxies fill the universe with low-frequency gravitational…
A city-sized collapsed star has generated a beam of matter and antimatter that stretches for trillions of miles. Data from NASA’s Chandra X-ray Observatory revealed…
Astronomers have imaged a beam of matter and antimatter that is 40 trillion miles long with NASA’s Chandra X-ray Observatory. The record-breaking beam is powered…
Astronomers have been using gravitational waves to detect merging black holes for years now, but may have to rely on pulsars – rapidly spinning neutron…
A new international study, led by an Australian researcher from the ARC Centre of Excellence for Gravitational Wave Discovery, searched for elusive continuous gravitational waves…
Researchers at the University of East Anglia and the University of Manchester have helped conduct a 16-year long experiment to challenge Einstein’s theory of general…
New methods of detecting ultra-low frequency gravitational waves can be combined with other, less sensitive measurements to deliver fresh insights into the early development of…
