NASA shares photo of 2 supermassive black holes. See pic

India TV News  

The National Aeronautics and Space Administration recently shared images of two supermassive black holes in Galaxy NGC 6240 which are in the process of merging. The supermassive black holes are in such proximity as they are spiraling toward each other — a process that began about 30 million years ago. "Seen as the bright dots near the center of this image, the black holes are just 3,000 light years apart," NASA said. The Chandra X-ray Observatory is a telescope specially designed to detect X-ray emissions from very hot regions of the universe such as exploded stars, clusters of galaxies, and matter around black holes.

The Mystery of How Supermassive Black Holes Merge

Wired  

The original version of this story appeared in Quanta Magazine. When galaxies merge, the supermassive black holes that sit in their centers must eventually merge, too, forming an even more gargantuan black hole. For decades, though, a question has vexed astrophysicists: How can supermassive black holes get close enough to spiral together and coalesce? These gravitational waves most likely come …

Webb telescope uncovers merger of two massive black holes from early universe

Associated Press  

CAPE CANAVERAL, Fla. — The Webb Space Telescope has discovered the earliest known merger of black holes. These two gigantic black holes and their galaxies consolidated just 740 million years after the universe-forming Big Bang. The latest findings, published in the Monthly Notices of the Royal Astronomical Society, suggest mergers are how black holes can grow so rapidly — “even …

Astronomers find signs for black holes merging over time forming larger black holes

Firstpost  

Astronomers have found evidence for a large number of double supermassive black holes, the likely precursors of gigantic black hole merging events. When supermassive binary black holes orbit, it causes the jet emanating from the nucleus of a galaxy to periodically change its direction. Astronomers studied the direction that these jets are emitted in, and variances in these directions; they …
