160 million suns are colliding with one another in complete darkness. It sounds unbelievable, but there's no other way of describing this pair of supermassive black holes that astronomers discovered in December 2021. The fusion of these two monsters will take place at a record close distance from earth: just 89 million light-years away.

Okay it's not that close, but one day we'll definitely invent faster than light spaceships and then we'll undoubtedly need a star guide map to avoid the most dangerous objects in the universe.
