The Star Spot

Feature Guest: Scott Bolton

It’s our cosmic backyard, and yet our own solar system is still full of surprises. Now it turns out we were “totally wrong” when it comes to just about everything we thought we knew about Jupiter. That’s not me speaking, it’s Scott Bolton, principal investigator for the NASA Juno mission to Jupiter. From its magnetic field and atmosphere down to its very core, Jupiter is being rediscovered and transformed. Today we’re joined here at The Star Spot by Dr. Bolton to discuss the rewriting of our textbook on the solar system’s biggest world.

Feature Guest: Jason Hessels

The one thing we thought we knew about fast radio blasts was that these mysterious one-off phenomena must be associated with some of the most cataclysmic events in the universe. Then everything changed with last month’s announcement of the first ever detection of a source of repeating fast radio bursts. Today we’re joined at The Star Spot by co-discover Jason Hessels to rule on an important question: are scientists back to the drawing board or did they just achieve a breakthrough in our efforts to unlock this puzzle.

Europa is a tantalizing destination for exploration, but Dave worries that if we visit we might quickly find ourselves on thin ice. Then Maya reports on a windy conundrum surrounding hot Jupiters. And Tony brings new insights into the most powerful explosions in our Universe. Care to make your very own gamma ray burst?
