Using telescopes from the European Southern Observatory (ESO) and other organisations around the world, astronomers have spotted a rare blast of light from a star being ripped apart by a supermassive black hole. The phenomenon, known as a tidal disruption event, is the closest such flare recorded to date at just over 215 million light-years from Earth, and has been studied in unprecedented detail. The research is published today in Monthly Notices of the Royal Astronomical Society.
“The idea of a black hole ‘sucking in’ a nearby star sounds like science fiction. But this is exactly what happens in a tidal disruption event,” says Matt Nicholl, a lecturer and Royal Astronomical Society research fellow at the University of Birmingham, UK, and the lead author of the new study. But these tidal disruption events, where a star experiences what’s known as spaghettification as it’s sucked in by a black hole,
A rare blast of light, emitted by a star as it is sucked in by a supermassive black hole, has been spotted by scientists using telescopes from around the world.
The phenomenon, known as a tidal disruption event, is the closest flare of its kind yet recorded, occurring just 215 million light-years from Earth. It is caused when a star passes too close to a black hole and the extreme gravitational pull from the black hole shreds the star into thin streams of material — a process called ‘spaghettification’. During this process some of the material falls into the black hole, releasing a bright flare of energy which astronomers can detect.
Tidal disruption events are rare and not always easy to study because they are usually obscured by a curtain of dust and debris. An international team of scientists led by the University of Birmingham were able to study this
New body camera footage obtained by Vice News purportedly shows what happened on March 13 in the moments after Louisville Metro Police officers raided the home of Breonna Taylor, who was shot and killed.
One video shows an officer, which Vice News says appears to be former Detective Brett Hankison, entering Taylor’s apartment after the shootings and ask about shell casings that are on the floor. He’s soon told by another unidentified officer that he should “back out” until LMPD’s Public Integrity

Warhammer 40,000: Dawn of War 2

Year: 2009 Developer: Relic
The first Dawn of War let me play with armies bigger than I could ever afford when I played Warhammer 40,000 on a ping-pong table with styrofoam hills on it. Every click-and-drag put battalions of troops and entire tank platoons under my command.
Then Dawn of War 2 came along. On most maps, it gives you four small squads—one of which is just your commander. It takes some getting used to. Thing is, each of those squads is like a character in an RPG. They level up and collect gear and unlock abilities. In most engagements the scouts begin in hiding, decloaking before the heavy weapons focus fire or the assault squad jetpacks over the top or the tactical squad taunts. What
