A new theory could change our understanding of the moons in our solar system – and the genesis of life itself.
If you’re looking for life, you’d do well to look for some moons.

Pluto's moon Charon seems to have had a violent past, with icy volcanoes leaving huge fractures.
Space scientists have a busy decade ahead with plans to visit Jupiter, Mars, Mercury and other interplanetary bodies all on the cards.
What secrets will space reveal?
Why the Breakthrough Listen project is a step in the right direction in our hunt for life beyond Earth.
