Astronomers have discovered the fastest known star in our galaxy, the Milky Way, orbiting the black hole at its center.

Well, astronomers have now spotted one of those stars that can only be seen with special high-tech telescopes travelling around a giant black hole at an incredible speed.

The researchers propose that this dot is a black hole star — an enormous, hypothetical ball of dense gas that surrounds and is superheated by a giant black hole.
