A group-analysis of 30 exoplanets orbiting distant stars suggests that size, not mass, is a key factor in whether a planet’s atmosphere can be detected.
The mining of resources contained in asteroids, for use as propellant, building materials or in life-support systems, has the potential to revolutionise exploration of our Solar System.
