Astronomer Dr Grant Christie joins Graeme Hill to talk the latest in Astronomy.

A beautiful image of Saturn’s moon, Enceladus, has been released revealing its fine detailing.

Enceladus famously has ice geysers inside its core which heats the ocean underneath the ice.

The geysers shoot organic material into space through cracks which can be noticed in the photograph taken by Cassini.

“It’s a hot prospect for possible life”.

It has always been assumed that Uranus must have taken a heavy hit for its rotational axis to be rolled on its side.

Dr Christie and Graeme discuss this computer simulation that theorises the collision type.

Plus why did we think there were canals on Mars? Another Chinese space “office” is set to fall out of the sky?

Middleweight Black Holes and how a huge piece of luck led to the discovery of Pluto.
