Black Hole

In 2015, when scientists, for the first time ever, directly detected gravitational waves—ripples in spacetime—from colliding black holes, the result came as a shock to some astronomers. Based on previous studies of black holes using x-rays, many experts expec…

Astronomers used new data to measure the mass of a black hole in the central bright galaxy shown here: It's 40 billion times more massive than our Sun. Matthias Kluge/USM/MPE About 700 million light-years from earth, in the swirling heart of the brightest g…

A team of international scientists spotted a stellar black hole three-and-a-half times greater than anyone thought possible. Researchers previously estimated the mass of an individual black hole in our galaxy at no more than 20 times that of the sun. Jifeng…

The team used China's Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) to find stars orbiting objects that are seemingly invisible -- a technique that had been proposed back in 1783, but hadn't really been possible until recently. They then …

Scientists recently found a black hole so big that theory strains explain it, a new study reports. A Chinese-led team discovered a stellar-mass black hole that appears to be 68 times heftier than Earth's sun — nearly three times bigger than the heaviest …

Humankind caught its first glimpse of a black hole on April 10, 2019. The Event Horizon Telescope (EHT) team, which uses an Earth-spanning network of radio observatories acting in concert, shared images it had captured of an apparent black hole with 6.5 billi…
