Astronomers Just Found an Absolutely Gargantuan Black Hole The Mass of 40 Billion Suns

Astronomers Just Found an Absolutely Gargantuan Black Hole The Mass of 40 Billion Suns Black holes can get pretty big, but there's a special class that is the biggest of the big, absolute yawning monster black holes. And astronomers seem to have found an absolute specimen, clocking in at 40 billion times the mass of the Sun. It's at the centre of a galaxy called Holmberg 15A, a supergiant elliptical galaxy around 700 million light-years away, which in turn sits at the centre of the Abell 85 galaxy cluster. The object is one of the biggest black holes ever found, and the biggest found by tracking the movement of the stars around it.

Astronomers have discovered a 13-billion-year-old galaxy cluster that is the earliest ever observed, according to a paper released Friday, a finding that may hold clues about how the universe developed.

Such an early-stage cluster -- called a protocluster -- is "not easy to find", Yuichi Harikane, a researcher at the National Astronomical Observatory of Japan who led the international team, said in a press release.

"A protocluster is a rare and special system with an extremely high density," Harikane said, adding that the researchers used the wide viewing field of the Subaru telescope in Hawaii to "map a large area of the sky" in their search.

Scientists stunned after spotting record-shattering supernova

Scientists stunned after spotting record-shattering supernova Scientists have a pretty good handle on the life cycle of various stars. They know the types of stars that are likely to die in fiery supernova blasts, and they know that not all supernova are created equal. Still, space has many untold secrets, and a new study published in The Astrophysical Journal reveals that scientists had their understanding of supernova thrown into question after observing an explosion so massive that they initially thought their instruments had broken.

The discovery of the protocluster, a collection of 12 galaxies, suggests that large cosmic structures were present in the very early stages of the universe, which scientists believe was born 13.8 billion years ago.

One of the 12 galaxies is known as Himiko, a giant gas cloud found in 2009 by using the same telescope.

"It is reasonable to find a protocluster near a massive object, such as Himiko. However, we're surprised to see that Himiko was located... on the edge 500 million light-years away from the center," the paper's co-author Masami Ouchi said.

"It is still not understood why Himiko is not located in the centre," he said.

"These results will be key for understanding the relationship between clusters and massive galaxies."

The team included scientists from Imperial College London and the study is published in Friday's Astrophysical Journal.

Astronomers just discovered an invisible galaxy from the dawn of the universe .
It took 12.5 billion years for the signal from this nearly mythical galaxy to reach us.The University of Arizona on Tuesday dropped some colorful words to describe the galaxy: monster, beast, ghostly. "Like a cosmic Yeti, the scientific community generally regarded these galaxies as folklore, given the lack of evidence of their existence," the university said in a statement.
