When scientists recorded a rippling in space-time, followed within two seconds by an associated burst of light observed by dozens of telescopes around the globe,…
Astronomers observe a binary neutron star merger through gravitational waves detected by the Advanced LIGO and Advanced Virgo detectors. On August 17, the Laser Interferometry…
This illustration shows the hot, dense, expanding cloud of debris stripped from two neutron stars just before they collided. Within this neutron-rich debris, large quantities…
Marking the beginning of a new era in astrophysics, astronomers have detected gravitational waves and electromagnetic radiation, or light, from the same event for the…
Using the NASA/ESA Hubble Space Telescope, astronomers have observed a visible counterpart to gravitational waves for the first time: a kilonova from merging neutron stars….
A new NASA mission is headed for the International Space Station next month to observe one of the strangest observable objects in the universe. The…
A team of astronomers studying the superluminous supernova Gaia6apd has concluded in part from the behavior of its extraordinary ultraviolet emission that it is powered…
Using ESO’s Very Large Telescope, astronomers may have found the first observational indications of a strange quantum effect, first predicted in the 1930s. The polarization…
Using data from Chandra, astronomers have the strongest evidence to date that violent stellar mergers produce pencil-thin jets. This result has implications for estimating the…
NASA’s Chandra X-ray Observatory has captured x-ray echoes from a neutron star, allowing astronomers to pinpoint the distance to Circinus X-1 from Earth. Astronomers using…
A new study examines in what sense a neutron star-black hole binary could be the ‘holy grail’ for testing gravity. The intermittent light emitted by…
A newly published study details how scientists developed a new way to use gravitational waves to measure the expansion rate of the universe. In a…
A new study from astrophysicists at the University of Warwick reveals that calcium-rich supernovae are likely created by white dwarf stars crashing into neutron stars….
A team of astronomers has discovered the first Thorne-Żytkow object, a hybrid star formed by the interaction of a red supergiant and a neutron star…
This XMM-Newton image reveals a strongly magnetized, rotating neutron star and the remains of the explosion that generated it. Massive stars end their lives with…
A newly released video from NASA shows a pair of neutron stars colliding and ripping each other apart to form a black hole. This supercomputer…
By using the space between stars and galaxies as a giant lens, astronomers made the highest resolution measurement ever achieved of a distant neutron star….
