Scientists have discovered a black hole, that really shouldn't exist.
The black hole is described as a stellar black hole.
A stellar black hole is a black hole formed by the gravitational collapse of a star.
This black hole is located roughly 15,000 light-years away and has a mass 70 times greater than the sun.
Chinese researchers published their findings in the journal "Nature".
The black hole is twice the size of what they believed was possible in our galaxy.
