Star Discovered in Closest Known Orbit Around Likely Black Hole Astronomers have found evidence for a star that whips around a black hole about twice an hour. This may be the tightest orbital dance ever witnessed for a likely black hole and a companion star. This discovery was made using NASA’s Chandra X-ray Observatory as well as NASA’s NuSTAR and CSIRO’s Australia Telescope Compact Array (ATCA). The close-in stellar couple – known as a binary…"Closest Orbit Around Black Hole"
Are aliens trying to tell us something?

Nobody knows what causes these powerful bursts, but some have even speculated that the signals could be transmitted by distant alien civilisations. In fact, astronomers are so perplexed by the phenomenon that it is…"Aliens trying to tell us something?"
