Scientists have uncovered the strongest evidence yet for the existence of elusive intermediate-mass black holes (IMBHs), long thought to be the missing link between stellar-mass and supermassive black holes.

We all know that black holes can devour stars, rip them apart and consume their remnants. But that only happens if a star passes too close to a black hole. What if a star gets close enough to a star to experience strong tidal effects,

The black hole at the heart of galaxy SDSS1335+0728, located 300 million light-years away, was quiet for decades as it consumed little matter and was in a dormant state. But recently it suddenly lit up and began spewing out X-rays as it woke up and started feeding.
