LOFAR/LOL Survey
Astronomers in Europe compiled the most detailed map of black holes to date.
Their map of the northern sky shows 25,000 white dots, each representing a supermassive black hole.
The image above may look like a fairly normal picture of the night sky, but what you re looking at is a lot more special than just glittering stars. Each of those 25,000 white dots is an active supermassive black hole.
And each of those black holes is devouring material at the heart of a galaxy millions of light-years away that s how they could be pinpointed at all.
In a new study, astronomers created the most detailed map to date of black holes at low radio frequencies, an achievement that took years and a Europe-sized radio telescope to compile.
