First detection of light from behind a black hole

Watching X-rays flung out into the universe by the supermassive black hole at the center of a galaxy 800 million light-years away, Stanford University astrophysicist Dan Wilkins noticed an intriguing pattern. He observed ...

Finding the source of the impactor that wiped out the dinosaurs

The impactor believed to have wiped out the dinosaurs and other life forms on Earth some 66 million years ago likely came from the outer half of the main asteroid belt, a region previously thought to produce few impactors. ...

First test of Europe's new space brain

ESA has successfully operated a spacecraft with Europe's next-generation mission control system for the first time. The powerful software, named the "European Ground System—Common Core' (EGS-CC), will be the 'brain' of ...

On the hunt for 'hierarchical' black holes

Black holes, detected by their gravitational wave signal as they collide with other black holes, could be the product of much earlier parent collisions. Such an event has only been hinted at so far, but scientists at the ...

Three dwarf spheroidal galaxies found to rotate

An international team of astrophysicists from the Instituto de Astrofísica de Canarias (IAC), the University of La Laguna (ULL) and the Space Telescope Science Institute (STScI, U.S.) has discovered the presence of transverse ...

Global project observes rare meteor showers and meteorite falls

As billionaires battle it out in a space race that only a handful of the world's richest persons can play, a highly inclusive international project is looking in the other direction–what's flying towards Earth–and all ...

Fermi spots a supernova's 'fizzled' gamma-ray burst

On Aug. 26, 2020, NASA's Fermi Gamma-ray Space Telescope detected a pulse of high-energy radiation that had been racing toward Earth for nearly half the present age of the universe. Lasting only about a second, it turned ...

Astronomers seek evidence of tech built by aliens

An international team of scientists led by a prominent Harvard astronomer announced a new initiative Monday to look for evidence of technology built by extraterrestrial civilizations.

Astronomers uncover briefest supernova-powered gamma-ray burst

Astronomers have discovered the shortest-ever gamma-ray burst (GRB) caused by the implosion of a massive star. Using the international Gemini Observatory, a program of NSF's NOIRLab, astronomers identified the cause of this ...
