The Star Spot

Feature Guest: Marco Delbo

The main belt asteroids are among the most ancient of all bodies in the solar system. This summer astronomers announced the discovery of what’s being called a primordial asteroid family. These asteroids are so old that their formation predates the migration of Jupiter, which may have passed through the asteroid belt while travelling to its current location in the solar system. Today the discovery team leader Marco Delbo joins us here at The Star Spot to explain how we can learn about the biggest objects in the solar system by studying some of the smallest.

Tony goes a little apocalyptic when he discovers that a barrage of comets are heading toward the inner solar system… in a little over a million years. Then Maya reports on the exotic and diverse names now officially assigned to Pluto’s recently discovered surface features. Here’s a hint: the underworld is a popular destination on this little world.

Feature Guest: Ravi Desai

It was recently reported that Saturn’s moon Titan harbours complex chemistry the likes of which we’ve never before seen in our solar system. On today’s episode of The Star Spot, the leader of the discovery Ravi Desai explains the implication of discovering these building blocks of life on a world that many are now calling the most habitable location beyond Earth.

Good news from Tony. The ocean worlds of Europa and Enceladus will be prime targets for the James Webb Space Telescope. Then Dave tells us how we finally mapped the surface of a second star - only to learn how little we know about our own sun’s fate. And finally Maya with the weather report: it’s raining diamonds in the outer solar system!
