Feature Guest: Jorge Zuluaga

Astronomers have yet to confirm a single detection of an exomoon, that is a moon orbiting a planet outside our solar system. Now it turns out at least part of the explanation is that we may have been looking in the wrong place all this time. Introducing ploonets. No, I did not just mispronounce the word planet. Today we’re joined here at The Star Spot by Jorge Zuluaga, whose team coined the name to describe a moon that has gone rogue, and while it may sound exotic, a speculative theory posits that ploonets could have played a key role in the evolution of our very own planet.    


Current in Space

Tony is back with an exciting discovery made in fresh snow in Antarctica: an isotope that can only have been manufactured in one place – the infernal heart of a supernova. Then Joseph and Tony once again ask the cosmic question: what are fast radio bursts, or FRBs, as eight more repeating FRBs have been detected in deep space, and we just may be on the cusp of solving the mystery. Finally, Amelia and Tony talk about a glitch. A software glitch? No. A neutron star glitch!
