The new NASA simulation shows with unprecedented details how a black hole is formed. From the image you can see a celestial body in the shade, surrounded by a disc of very hot gas material.
Thanks to the very intense gravitational field, a black hole can attract everything to itself. The celestial body absorbs matter while around it forms a ring of gaseous material expelled due to the galaxy's rotation around its center. Gravity, which sucks everything, bends the light and creates a luminous ring of photons that apparently outlines the border of a black hole.
On April 10, an international team with complex radio telescopes took the first photo of a celestial body called M87, 56 million light-years away.
