Supermassive black holes put a brake on stellar births

Black holes with masses equivalent to millions of suns do put a brake on the birth of new stars, say astronomers. Using machine learning and three state-of-the-art simulations to back up results from a large sky survey, researchers ...

New detection method for quasars in the early universe

Astronomers from Leiden Observatory have developed a new method to find distant quasars and better distinguish them from other objects that look like them, using machine learning techniques. The research result has been accepted ...

Extraordinary black hole found in neighboring galaxy

Astronomers have discovered a black hole unlike any other. At one hundred thousand solar masses, it is smaller than the black holes we have found at the centers of galaxies, but bigger than the black holes that are born when ...

Black holes and dark matter—are they one and the same?

Primordial black holes created in the first instants after the Big Bang—tiny ones smaller than the head of a pin and supermassive ones covering billions of miles—may account for all of the dark matter in the universe.

Image: Hubble snaps a stunning spiral's side

This astronomical portrait from the NASA/ESA Hubble Space Telescope showcases an edge-on view of the majestic spiral galaxy UGC 11537. The infrared and visible light capabilities of Hubble's Wide Field Camera 3 have captured ...
