(CNN) - Scientists have discovered a “monster black hole," but they said it’s so big that it shouldn’t actually exist.
It’s a stellar black hole, which is the kind that forms following the death or explosion of a massive star.
Before this discovery, researchers thought the size limit for stellar black holes was less than 20 times the mass of the sun, but this black hole, known as LB-1, appears to debunk that theory.
Its mass is 70 times larger than the sun, according to the Chinese Academy of Sciences.
No worries, though: This monster is 15,000 light years away from Earth.
While LB-1 is large for a stellar black hole, there are several types of black holes out there. Supermassive black holes, which are theorized to form when stellar black holes merge, are much larger.
The findings were published in Wednesday’s edition of the journal Nature.
