      There are some good astrophysics questions today 🙂

      Saturn is described as being a ‘gas giant’. This is because the outside of it that we see is mainly made up of different gases (like hydrogen and helium). There may be a solid core in the centre made from rock, like the Earth (I don’t know if scientists know that or not yet).

      Jupiter, Uranus and Neptune are also gas giants.

      I think I’ve seen a few questions on space from you – is space one of your favourite science subjects?

      Thanks, Emma. I always knew that the rings of Saturn are basically gas, but hadn’t realised that the whole planet was actually made up mainly of gas.
