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. Current in Space 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. About Our Guest Marco Delbo is an Astronomer with the Observatory of Cote d'Azur and with France’s National Institute for Earth Sciences and Astronomy, located at the University of Nice-Sophia.
