Black holes aren't stationary in space; in fact, they can be quite active in their movements. But because they are completely dark and can't be observed directly, they're not easy to study. Scientists have finally figured out the precise timing of a complicated dance between two enormous black holes, revealing…

Usually, a brush with a black hole marks the end of an object’s journey – after all, even light itself can’t escape the intense gravity. But in the galaxy GSN 069, a star has managed to survive a close encounter with a black hole, ending up in orbit around it.…
