Dr. Michael McDonald of MIT’s Kavli Institute for Astrophysics and Space Research and co-authors have uncovered a new massive cluster of galaxies hiding...
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...
Astronomers using NSF’s Very Long Baseline Array (VLBA) have found a quasar with the brightest radio emission ever observed in the early Universe.
An...
A multinational group of astronomers has imaged the formation and expansion of a fast-moving jet of material ejected when the intense gravity of a supermassive...
When two galaxies collide, their central supermassive black holes also smash together. But before they do, these galaxies often flicker on, absorbing huge...
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 data from the CanariCam infrared camera on the Gran Telescopio Canarias, astronomers have created a high resolution map of the magnetic field lines...
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...
Supermassive black holes, with masses more than a million times that of the Sun, reside at the centers of all massive galaxies. A new study published in...
New findings from a team of astronomers at the University of California, San Diego, and elsewhere increase understanding of how powerful winds generated...
An international group of astronomers has discovered and measured the distance to the most distant supermassive black hole ever found.
Artist’s conception...
Using X-ray data from NASA’s Chandra X-ray Observatory and optical data from ground-based telescopes, astronomers have spotted what could be the most...
