Conditions favorable for gravitational wave-emitting mergers of massive black holes exist in the outer gas disks of big spiral galaxies, according to a...
At the center of our Milky Way Galaxy lies the 4-million-solar-mass black hole named Sagittarius A*. This gravitational monster is surrounded by a group...
When two galaxies collide, their central supermassive black holes also smash together. But before they do, these galaxies often flicker on, absorbing huge...
A new study using X-ray data from NASA’s Chandra X-ray Observatory indicates that the neutron star merger that became the gravitational wave source,...
A supermassive black hole in the center of the ultra-luminous quasar SMSS J215728.21-360215.1 (J2157-3602 for short) devours a mass equivalent to our Sun...
In a new study, a team of astronomers from Yale Center for Astronomy & Astrophysics, the University of Washington, Institut d’Astrophysique de Paris,...
NGC 6240 is a pair of merging galaxies approximately 400 million light-years away in the constellation Ophiuchus. It spans 300,000 light-years and has...
Astronomers using NASA’s Chandra X-ray Observatory have discovered what they believe are 12 stellar-mass black holes gathered around Sagittarius A*,...
Astronomers have detected radio echoes of a supermassive black hole feeding on a star, suggesting the black hole emits a jet of energy proportional to...
Using NASA’s Chandra X-ray Observatory, astronomers have found evidence for what is likely the most massive black holes ever detected.
A massive black...
High resolution observations using the Atacama Large Millimeter/submillimeter Array (ALMA) have revealed the presence of a rotating dusty gaseous torus...
A team of astronomers led by University of Colorado Boulder scientists has discovered a mechanism that explains the persistence of asymmetrical star clusters...
An international team of physicists has created the first small-scale replica of gamma ray bursts in a laboratory, opening up a whole new way to investigate...
An international team of astronomers led by Georg-August-Universität Göttingen researcher Benjamin Giesers has discovered a star in the globular cluster...
Using the Arecibo Observatory in Puerto Rico and the Green Bank Telescope in West Virginia, astronomers have gained new insight into the extreme home of...
