Just a short 25 years ago, if you had asked astronomers and astrophysicists whether there were planets around other stars, the answer would have been, “probably, but we don’t know for sure.” Thanks to
So far, however, warped spacetime is keeping the events a secret. Image: black hole artist's conception/Wikimedia Black holes aren’t eternal. Like everything else in the cosmos, they have a lifespan: life,

A black hole has woken up... and it's hungry. The European Space Agency says V404 Cygni, a binary system of a black hole and a star, has gone from practically invisible to one of the brightest objects
