The Star Spot

Feature Guest: Jan Cami

Did you know that buckyballs, complex soccer-ball shaped molecules formed from 60 carbon atoms, were recently discovered deep in interstellar space. Atoms and molecules may be small, but they can tell us lot about the very large, from the temperature of stars to the evolution of galaxies to the startling locations where life might be found. For more on the chemistry of the universe, today I’m joined at the start spot by Jan Kami

Feature Guest: Pauline Barmby

Just like the cities of our world, galaxies are the busy and over-crowded population centres where so much of the action takes place in our universe. The study of globular clusters and starburst galaxies are providing new insights into the how these cities of the cosmos were built. To share with us new discoveries from the Spitzer space telescope, including gossip about the weird behaviour of our next door metropolis, the Andromeda Galaxy, today I’m joined at the star spot by Pauline Barmby.
