5 Amazing Facts About Black Holes By NASA
According To NASA, Black holes are among the most mysterious cosmic objects, much studied but not fully understood. These objects aren’t really holes. They’re huge concentrations of matter packed into very tiny spaces. A black hole is so dense that gravity just beneath its surface, the event horizon, is strong enough that nothing – not even light – can escape.

Rare crash of two mismatched black holes detected for the first time ever
In a major discovery, scientists have succeeded in detecting rare crash of two mismatched black holes for the first time ever. On April 12, 2019, a signal of space-time ripples was picked up by gravitational wave detectors. These ripples were caused by colliding black holes. The scientists then studied the detection closely and found that the detection did not match the signals seen by them so far.
