The water you're drinking could be older than the Sun! New ALMA observations show that water molecules carry the same chemical fingerprint all the way from star-forming clouds to planet-forming discs and comets, meaning these molecules have remained unaltered since they first formed. What is this chemical signature and how do astronomers use it to trace the history of water? Find out:

Black holes don’t suck, they get fed! The belief that black holes simply suck in anything that comes near them is wrong. Material can only fall into a black hole when it’s slowed down somehow.
