We could be exploring the oceans of Jupiter's and Saturn's icy moons in a couple of decades. Here's what we need to work out.

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.
Why the Breakthrough Listen project is a step in the right direction in our hunt for life beyond Earth.
