Yesterday, NASA reported that they have the first solid evidence for ice (from water) on the moon. Now we know there is water on both Mars and the moon, soon I think we will hear there are little bacteria-life things living there too. DNA can survive space and be transported from a planet to another through asteroids, so why not - life on other planets than Earth is quite likely I think. The first life on Earth wasn't living in an oxygen-rich atmosphere, it survived in what we think are hellish environments - boiling acid mudpots, deep-sea hot vents, methane gas filled environments, and other places of what we now think are extreme environments because we are used to the extreme oxygen-rich environment we live in. But it appears that early life on Earth at least was dependent on water. This is all very exciting - congratulations NASA!The stamp of the day are ice crystals (snow flakes) on Swedish stamps.
