Ohio State University astronomers have identified about 116,000 new variable stars, according to a new paper. These heavenly bodies were found by The All-Sky Automated Survey for Supernovae (ASAS-SN), a network of 20 telescopes around the world which

Record-breaking black hole discovered; Named 'The Unicorn' Astronomers call it “The Unicorn,” breaking the record for the closest black hole to Earth and one of the smallest on record.

Discoveries made from outside our planet, however, are even harder, especially when these discoveries that are several thousand light years away. With the advancement in technology and...

Newfound black hole may be the closest to Earth Dan Falk © Illustration by Lauren Fanfer and Ohio State University. TK How small can a black hole be? For several decades, astronomers have worked to answer this question by tallying the black holes in our corner of the universe. They’ve found plenty of big and medium-size ones over the years—including a supermassive monster at the heart of our galaxy. But until recently, they’ve seen no signs of small ones, and that’s presented a long-standing mystery in astrophysics. The discovery “implies that there are many more ...

“There appears to be a theoretical maximum to the mass of a neutron star at up to 3 solar masses,” Jayasinghe, who recently led a study published in Astrobiology, told SYFY WIRE. “So the Unicorn is truly one of the smallest black holes possible. Finding these systems will help scientists understand the formation mechanisms of black holes and neutron stars.” The Unicorn is a mass gap compact object some 1,500 light years from Earth. Rare and not well understood, these are cosmic objects that are by no means small to human eyes. The heaviest neutron star that has been found so far is 2...
