Feature Guest: Arjun Berera

Many of you are familiar with the idea of panspermia, the theory that life spreads itself throughout the galaxy by travelling from one world to another. We often think of big objects like asteroids, comets or spacecraft. But a new idea has emerged, and it’s must smaller: dust. Astronomer Arjun Berera joins me here at The Star Spot to discuss his new study, which considers whether alien life can hitchhike between planets on streams of space dust and if life on Earth might have just such an origin.
