A 20-year-old transient man in Idaho set a wildfire and then fatally shot two firefighters and wounded another after they asked him to move his vehicle, leading to a lengthy shootout and his subsequent suicide; the motive remains unknown.
Astronomers have discovered a supermassive black hole, known as J221951, that suddenly "switched on" and became one of the most dramatic bursts of brightness ever seen. The black hole was found using various telescopes and instruments, including NASA's Swift Observatory and the Hubble Space Telescope. The observations revealed that J221951 is located about 10 billion light-years away and is not associated with a previously-detected gravitational wave event. The researchers believe that the black hole consumed surrounding material rapidly, causing a huge release of energy. This discovery adds to our understanding of the active role supermassive black holes play in a galaxy's star formation.
Astronomers have discovered an extremely bright and long-lived transient object, named "Scary Barbie," which is believed to be a supermassive black hole consuming a massive star through tidal disruption. The object is the most energetic phenomenon ever encountered and has lasted for over 800 days, much longer than usual transients. The discovery was made using big data analysis and AI engine, REFITT, which combs through millions of alerts from telescopes around the world. The discovery highlights that there are still mysteries to uncover in the universe.
