We’re back to a themeless questions show. We’re right across the Universe this time. Why are the planets lined up in a nice flat plane? Why are there no greenstars? And is the Oort Cloud contaminating our understanding of the cosmic microwave background radiation? If you’ve got a question for the Astronomy Cast team, please email it in to [email protected] and we’ll try to tackle it for a future show. Please include your location and a way to pronounce your name.
