Instead, it seems to be a gas cloud moving at huge speeds right in the direction of the black hole. But what really rang along bells was the way it had changed shape.
We see that this gas cloud as it moves closer and closer to the black hole, is getting spaghettified like you see it in school books according to the title shear 1 as we see at the title disruption by the black hole.
It's moving quite fast and it's not moving in a straight line but it's a curved line. And that's a very, very bad sign. Because it tells you, well, there are something acting 2 on it. It tells you, well, gravity is pulling on that object. It's pretty much directly head on, moving towards the centre of gravity, the black hole.
The team's observations suggest the object is a gas cloud, around three times the mass of the Earth. It seems they have discovered what is the great Holly 3 Grail for black hole scientists.
It almost goes straight in. Who aims that well we don't know. It's remarkable 4. It's almost straight in. Not quite, but pretty much and that means it will go deep, deep into the centre potential and therefore be sort of a, if you like, test, a test party for us to probe the environment of the black hole.
The gas cloud is advancing its speed of over 2,000 kilometres per second. The team are cautiously optimistic the gas cloud will continue to be shredded 5 by the extreme gravity surrounding the black hole. With every possibility, some of it will eventually be swallowed.
