Space around the Earth is full of junk and one of our listeners asks "what are we doing about that?"  To answer's this question we bring in an expert, Joshua Lurie and dive deep into ways to clean up after ourselves in space.  

Can we send a probe inside a black hole? And why are we so obsessed with the Milky Way? This and more in this episode of The Astroholic Explains!

In this episode we talk about globular clusters and how they help us work out the age of stars, and then return to our neighbourhood to investigate the rumour of an undiscovered planet in the Solar System.

This time we answer two questions from the same person. Laurie asks if other solar systems are likely to be similar to ours, and about the risk of pregnancy in space. 

In this episode we answer two different but equally important questions. What would the headlights on a spaceship moving at the speed of light look like, and are there actually aliens out there? 

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!
