This week we're meeting at Betelgeuse, hopping across to catch up with some cosmic twins, and then looking up to ask the Moon how it got there.

If you're having trouble finding anything we're talking about this week, we recommend listening to previous episodes of the Audio Guide.

If you'd like to try a Late Heavy Bombardment of your own, we recommend the part-game, part-simulator Universe Sandbox - you can get it at www.universesandbox.com.

When should I listen to this? : 7:30pm, any night between May 1st and May 8th.

Where should I be when listening? : Outside in your backyard or local park. Bring a jumper - it's getting chilly outside.

Music this week was featured Stellardrone, one of our Planetarium regulars - specifically, the tracks Red Giant, Cepheid, and In Time, used under a CC-BY license. You can find more at https://stellardrone.bandcamp.com/
