A flare-up in a jet of matter blasting from a monster black hole is giving astronomers an incredible light show. The outburst is coming from a blob of matter, called HST-1, embedded in the jet, a ...

A 3,000-light-year-long jet of plasma (superheated gas) shooting out from galaxy M87's supermassive black hole. The M87 galaxy is monstrous. NASA calls this jet "blowtorch-like," and it seems to be ...

High-speed gas shooting from the galaxy M87 is causing stars to go nova, a study suggests, and no one knows how. Alec Lessing, an undergraduate student at Stanford University, Michael Shara, an ...

A galaxy named Messier 87 (M87) has a monster at its heart that became famous when it was captured in the first-ever image of a black hole. Now, astronomers have revisited M87 and mapped out the ...

Using Event Horizon Telescope observations of M87's black hole from 2017, 2018 and 2021, "astronomers have found some changes ...

In a surprise finding, astronomers using NASA's Hubble Space Telescope have discovered that the blowtorch-like jet from a supermassive black hole at the core of a huge galaxy seems to cause stars to ...

A photo of the huge elliptical galaxy M87 [left] is compared to its three-dimensional shape as gleaned from meticulous observations made with the Hubble and Keck telescopes [right]. Because the galaxy ...

Seen from Earth, the giant elliptical galaxy M87 is just a two-dimensional blob, though one that appears perfectly symmetrical and thus a favored target of amateur astronomers. Yet, a new, highly ...

A massive international collaboration of researchers has released the first-ever direct image of the hellish environment surrounding a supermassive black hole. As part of the Event Horizon Telescope ...

This is an artist's concept looking down into the core of the giant elliptical galaxy M87. A supermassive black hole ejects a 3,000-light-year-long jet of plasma, traveling at nearly the speed of ...

From Earth, giant elliptical galaxies resemble highly symmetric blobs, but what's their real 3D structure? Astronomers have assembled one of the first 3D views of a giant elliptical galaxy, M87, whose ...
