A supermassive black hole with 200,000 solar masses is located in the middle of the dwarf galaxy Markarian 462 (Mrk 462), according to new research led by Dartmouth College astrophysicists. This graphic shows X-rays that NASA’s Chandra X-ray Observatory detected from the dwarf galaxy Mrk 462. This X-ray emission (inset)…

Hickox; Optical/IR: Pan-STARRS The discovery of a supermassive black hole in a relatively small galaxy could help astronomers unravel the mystery surrounding how the very biggest black holes grow. Researchers used NASA's Chandra X-ray Observatory to identify a black hole containing about 200,000…

Astronomers captured a stunning image of a black hole eruption in the galaxy Centaurus A. When seen from Earth, the ejection from Centaurus A presently expands eight degrees across the sky—the length of 16 full Moons laid next to each other. It was captured using the Murchison Widefield Array (MWA)…

Google Saturday's Google Doodle pays homage to the late Stephen Hawking, perhaps the most famous scientist of his time, who sought to explain the universe to millions. The renowned British theoretical physicist and cosmologist's work focused on increasing our understanding of black holes -- dying stars that've collapsed on themselves,…

Today's Google Doodle features a short animated version of Stephen Hawking's life story. Google Today’s Google Doodle honors the late physicist Stephen Hawking on his 80th birthday. Hawking was a renowned cosmologist, and he spent his career theorizing about the origins of the universe, the underlying structure of reality, and…

In 1997, cosmologists Stephen Hawking, Kip Thorne and John Preskill made a famous bet as to whether information that enters a black hole ceases to exist. Hawking and Thorne bet that information that enters a black hole is destroyed, while Preskill took the opposite view. Hawking’s research suggested that the…
