Mar. 9, 2017 — NASA's Hubble Space Telescope has found that the black hole at the center of our Milky Way galaxy ate its last big meal about 6 million years ago, when it consumed a large clump of infalling ... read more

Mar. 8, 2017 — A team of astronomers has doubled the number of known young, compact radio galaxies -- galaxies powered by newly energized black holes. The improved tally will help astronomers understand the ... read more

Mar. 1, 2017 — Scientists have made the most detailed observation yet of a black hole outflow, from the active galaxy IRAS 13224-3809. The outflow's temperature changed on time scales of less than an hour -- ... read more

Feb. 28, 2017 — When the universe was young, a supermassive black hole heaved out a jet of particle-infused energy that raced through space at nearly the speed of light. Billions of years later, scientists has ... read more

Feb. 27, 2017 — Astronomers have found evidence demonstrating that stars are ripped apart by supermassive black holes 100 times more often than previously ... read more

Brightest Neutron Star Yet Has a Multipolar Magnetic Field

Feb. 21, 2017 — Scientists have identified a neutron star that is consuming material so fast it emits more x-rays than any other. Its extreme brightness can only be explained if the star has a complex multipolar ... read more

Feb. 14, 2017 — Astronomers have discovered a surprising connection between a supermassive black hole and the galaxy where it resides. Powerful radio jets from the black hole - which normally suppress star formation ... read more

Feb. 8, 2017 — All known black holes fall into two categories: small, stellar-mass black holes weighing a few suns, and supermassive black holes weighing millions or billions of suns. Astronomers expect that ... read more

Feb. 6, 2017 — A giant black hole ripped apart a nearby star and then continued to feed off its remains for close to a decade, according to research. This black hole meal is more than 10 times longer than any other ... read more

Feb. 2, 2017 — By analyzing the gas motion of an extraordinarily fast-moving cosmic cloud in a corner of the Milky Way, astronomers found hints of a wandering black hole hidden in the cloud. This result marks the ... read more

Jan. 30, 2017 — NASA's Fermi Gamma-ray Space Telescope has identified the farthest gamma-ray blazars, a type of galaxy whose intense emissions are powered by supersized black holes. Light from the most distant ... read more

Jan. 13, 2017 — The beautiful spiral galaxy visible in the center of the image is known as RX J1140.1+0307, a galaxy in the Virgo constellation imaged by the NASA/ESA Hubble Space Telescope, and it presents an ... read more

Jan. 12, 2017 — Galaxies are merging all the time, even our own galaxy, the Milky Way. But how these mergers occur isn't entirely clear. An American astrophysicist will use a National Science Foundation grant ... read more

Jan. 11, 2017 — Every few thousand years, an unlucky star wanders too close to the black hole at the center of the Milky Way. The black hole's powerful gravity rips the star apart, sending a long streamer of ... read more

Jan. 8, 2017 — A black hole under investigation is so hidden that it requires highly sensitive observations in the highest energy X-rays to classify it as obscured. But they give themselves away when material they ... read more

Jan. 6, 2017 — Astronomers have discovered a cosmic one-two punch never seen before. By combining data from some of the best X-ray, optical and radio telescopes in the world, researchers have found out what happens ... read more

Jan. 5, 2017 — An unparalleled image from NASA's Chandra X-ray Observatory is giving astronomers the best look yet at the growth of black holes over billions of years beginning soon after the Big Bang. This is ... read more

Dec. 22, 2016 — An improved method for simulating collisionless accretion disk around the supermassive Sagittarius A* at center of the Milky Way has been described in a new ... read more

Number of Known Black Holes Expected to Double in Two Years With New Detection Method

Dec. 15, 2016 — A method that will detect roughly 10 black holes per year has now been developed, doubling the number currently known within two years, say scientists. They add that it will likely unlock the history ... read more

Dec. 15, 2016 — The brightest flash of light in the cosmos could be a rare event involving a star and a supermassive black ... read more
