Space 2 August 2021 By Leah Crane Black holes follow the no-hair theorem Bransgrove A., et al./American Physical Society Black holes with “hair” will quickly go bald. A key theoretical prediction about black holes called the no-hair theorem states that an isolated black hole can be described by just three…

In a short span of time, astronomers have taken us closer to black holes than ever with unprecedented images of the cosmic giants. Now, for the first time, scientists have seen the phenomena that takes place behind them. As part of the breakthrough, researchers witnessed and captured the light from…

Seen nearly edgewise, the turbulent disk of gas churning around a black hole takes on a crazy double-humped appearance. The black hole’s extreme gravity alters the paths of light coming from different parts of the disk, producing the warped image. The black hole’s extreme gravitational field redirects and distorts light…

A researcher at Saint Mary’s University in Halifax was part of a team of scientists that observed light coming from behind a black hole for the very first time, confirming a prediction from famous physicist Albert Einstein’s theory of general relativity. While scientists have seen X-ray emissions around black holes…

If you know what a black hole is, you're probably aware that it can contain as much mass as billions of stars, compressed into a much smaller space, and have such a powerful gravitational pull that even light can't escape its grasp. But even though it's not possible to see…

Using ESA’s XMM-Newton and NASA’s NuSTAR space telescopes, astronomers have observed X-ray flares emitted from around the supermassive black hole in a nearby galaxy called I Zwicky 1 (I Zw 1); further analysis of the flares has revealed short flashes of photons consistent with the re-emergence of emission from behind…

Stanford astrophysicist Dan Wilkins and his colleagues were studying a supermassive black hole when something caught their attention—​​ a series of bright flares of X-rays. The emission of such high-energy photons from a black hole was intriguing, but not necessarily unprecedented. Yet it was interesting enough for Wilkins to take…

Scientists have finally seen the backside of a black hole and in doing so, they've proved that a 1915 theory posited by Albert Einstein was correct. Einstein's 1915 Theory of General Relativity predicted that the gravitational pull of black holes is so large that black holes warp the fabric of…
