There has been quite a lot of excitement recently in the planetary sciences. If you haven’t already heard (if not, where have you been!?), it has now been confirmed that liquid water flows on the surface of Mars – this is almost old news now with the speed things travel on the internet!
This discovery is so new and exciting as they believe water is actually liquid and flowing on the surface of the planet, right now. We’ve known for a while that water exists on Mars, frozen in its ice caps, and we’ve also known that water once flowed but has since evaporated, but flowing water today is new.
