The supermassive black hole at the center of the Milky Way, Sagittarius A*, emits relatively little energy for its size, as much energy as Sol…
This new image from Hubble shows Abell 2261, a giant elliptical galaxy located about three billion light-years away that is roughly ten times the diameter…
A team of scientists discovered a star called S0-102 that orbits the black hole at the center of our Milky Way galaxy in 11.5 years….
NASA’s Swift satellite detected high-energy X-rays a few degrees from the center of our galaxy, toward the constellation Sagittarius. Produced by a rare X-ray nova,…
For the first time, international team of astronomers has measured a black hole’s “point of no return,” the closest distance that matter can approach before…
Using the Event Horizon Telescope, an international team of scientists has for the first time measured the radius of a black hole at the center…
A recently published study uses computer simulations to show for the first time what happens in the magnetized gas (plasma) in the last stages of…
Scientists at the Harvard-Smithsonian Center for Astrophysics believe that the recently discovered cloud of hydrogen and helium plunging toward the galactic center represents the shredded…
Documented in three new studies, data from NASA’s Wide-field Infrared Survey Explorer mission was used to discover millions of newfound supermassive black holes and extreme…
A newly published study describes the X-ray signal, called a quasi-periodic oscillation or QPO, that was observed the days following the last years discovery of…
Using radio telescopes, a team of scientists at Keio University has discovered several intermediate-mass black hole candidates, which are considered to be the “seeds” that…
Using three telescopes (Atacama Pathfinder Experiment (APEX) in Chile, Submillimeter Array (SMA) in Hawaii, and the Submillimeter Telescope (SMT) in Arizona) to create an interferometer,…
Using interferometric measurements to achieve extremely high angular resolutions, the RadioAstron mission will enable astronomers to study scientific topics like particle acceleration near supermassive black…
Scientists have been monitoring radio signals from the galaxy Arp 220, located 250 million light years from Earth, and now believe the radio emissions may…
While monitoring the movement of stars around the supermassive black hole at the center of our galaxy, astronomers discovered an ionized gas cloud with a…
A new study challenges prevailing ideas about how supermassive black holes grow in the centers of galaxies, finding that two supermassive black holes and their…
