Moon, Mars, Trappist 1 and Dinosaurs Reclassified

Guests galore as Andrew tries to fill the void left by Malcolm. Luke Jerram tells us about his stunning artwork Museum of the Moon, Emeline Bolmont tells us about the tidal effects on and of the Trappist 1 planets and Andrew is joined in the studio by Maddy Nichols and Steve Bullock to discuss all that and much more.

Dinosaurs are reclassified, the waters on Mars are Tsunamis in one report and not the cause of streaks in another.

This handy graphic from the BBC explains the Dinosaur reclassification we talk about.
