By using a technique called gravitational microlensing, a team of astronomers from the University of California, Berkeley, has discovered a ‘dark’ free-floating black hole in the Milky Way galaxy. This was the first time they found a free-floating black hole by observing the brightening of a more distant star as…

A blazar is a feeding supermassive black hole (SMBH) in the heart of a distant galaxy that produces a high-energy jet viewed face-on from Earth. They are among the most luminous and energetic objects in the Universe and are composed of ionized matter traveling at nearly the speed of light.…

This is an illustration of a close-up look at a black hole drifting through our Milky Way galaxy. ... The black hole distorts the space around it, which warps images of background stars lined up almost directly behind it. FECYT, IAC For the first time ever, astronomers using NASA’s Hubble…

Artist’s illustration of a black hole. Gravitational microlensing turns up black hole candidate, one of 200 million in the galaxy. When massive stars come to the end of their lives and explode in a supernova, they leave behind a black hole. It is estimated that about one in a thousand…

Black holes, by their nature, are invisible unless part of a stellar binary or surrounded by an accretion disk. Most stellar-sized black holes aren't, but astronomers have been searching for them through gravitational microlensing events, where the black hole brightens and distorts light from stars toward the galactic center. A…

Does this black hole seem as if it's expanding toward you? You're not alone. Some 86 percent of participants in a new study had the same experience. "The 'expanding hole' is a highly dynamic illusion: The circular smear or shadow gradient of the central black hole evokes a marked impression…

A team of astronomers led by scientists at the Center for Astrophysics | Harvard & Smithsonian who produced the first direct image of a black hole three years ago have now produced a portrait of a second, this time a much-anticipated glimpse of the supermassive blck hole at the center…
