What is black hole

BLACK holes could be a portal to another universe and our cosmos could have been born from one, a scientist has sensationally claimed.

Explore one of the great mysteries of the universe with this space science worksheet on black holes.

The very first image of the black hole at the centre of the Milky Way Galaxy a.k.a Sagittarius A*! As a physics undergraduate who not only hopes to do a PhD in Astrophysics but also study supermassive black holes like this one, this is absolutely amazing! (I may or may not have stared at this image for a good 20 minutes with my jaw on the floor.) So what are black holes? Why is this ‘orange blob’ so significant? And what does all of it mean?

A black hole’s spin is its event horizon’s rate of rotation, and astronomers measure it by studying X-rays from gas near the black hole.
