In this episode we tackle two more questions from our lovely listeners. The first is about what determines the rotation of planets and the second one focuses on the matter at hand: are we really made from stardust? 

In this episode, we answer two listeners' questions one about Flat-Earthers and one about astrology. Surprisingly, it is not as ranty as you might expect, at least not from Alfredo. No more spoilers, have a listen and get in touch if you have more questions. 

Almost 111 years after the Tunguska Event we answer our first (unexpectedly nepotistic) crowdsourced question about the risk of an asteroid impact, and we try to wrap our heads around just how devastating such events could be!

In this episode we investigate the Goldilocks Zone, the area around a star where planets might have the right conditions for habitability, and we travel through the solar system to look for life outside Earth.

The Milky Way is on a collision course with the closest major galaxy, Andromeda. What's going to happen to our solar system when the two objects finally collide? Find out in this episode of The Astroholic Explains!

Where do alien-leprechauns hide their gold? Alfredo explores the colour spectrum, and tells us what rainbows on other worlds could look like.

Chris has a burning question about mass and why the universe doesn't just collapse onto itself. Alfredo gives us the low down on what's up with gravity!
