Black hole shreds distant 'super sun,' unleashing a spectacular event known as the Whippet
Credit: CC0 Public Domain A black hole has shredded a massive star like it was "preparing a snack for lunch," according to a team of scientists at the American Astronomical Society's annual meeting (5–8 January). The cosmic mismatch was witnessed by astronomers around the world and reported at the AAS conference in Phoenix, Arizona, where the unfortunate star was described as "torn up" and devoured bit by bit by the huge gravity of the black hole.
Extremely stripped supernova reveals a silicon and sulfur formation site

Abstract Stars are initially powered by the fusion of hydrogen to helium. These ashes serve as fuel in a series of stages1,2,3, transforming massive stars into a structure of shells. These are composed of natal hydrogen on the outside and consecutively heavier compositions inside, predicted to be dominated by He, C/O, O/Ne/Mg and O/Si/S (refs. 4,5). Silicon and sulfur are fused into iron, leading to the collapse of the core and either a supernova explosion or the formation of a black hole6,7,8,9.

We Think We’ve Spotted the Mysterious Birth of a Black Hole

In the past few years, we have finally captured actual photos of these fearsome creatures and measured the gravitational waves – ripples in spacetime – that they create when colliding. But there’s still a lot we don’t know about black holes. One of the biggest enigmas is exactly how they form in the first place.

It’s long been a mystery how black holes form, now astronomers are on the verge of cracking it.
