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…

Investigated by the SOAR Telescope operated by NOIRLab, the binary system is the first to be found at the penultimate stage of its evolution. Using…
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…
Astronomers have discovered a pulsar—a dense and rapidly spinning neutron star sending radio waves into the cosmos—using a low-frequency radio telescope in outback Australia. The…
A group of astronomers has discovered 8 millisecond pulsars located within dense clusters of stars, known as “globular clusters,” using South Africa’s MeerKAT radio telescope….
X-ray emissions from the Crab Pulsar are more intense during giant radio pulses (GRPs), researchers report. The new findings provide constraints on the mechanisms underlying…
Using coordinated observations of the Crab pulsar in a number of frequencies, a team of scientists has discovered that the “giant radio pulses” that it…
A global science collaboration using data from NASA’s Neutron star Interior Composition Explorer (NICER) telescope on the International Space Station has discovered X-ray surges accompanying…
