Fundamentally important for the habitability of a planet is whether or not it can hold onto an atmosphere. A new study by has shown that young stars can rapidly destroy the atmospheres of Earth-like planets, which is a significant additional diff

The drone doesn’t carry any payload other than its own bulk, which means it may be the first practical coun
