The speaker in this video is a little hard to understand, but he said something very interesting – that the salt in the water, plus other discoveries they made, mean that there are the right chemicals for possibly creating life. Forget life on other planets – we should be looking for life on other moons!
Ever wondered what a volcano erupting would look like if you could fly over the top of it? This short video was taken from the International Space Station as it passed over the Sarychev Volcano on an island that is part of Russia:
