A feast of galaxies

Air Date: March 1, 2010

Our Milky Way has had a pretty lax policy when it comes to allowing globular clusters in. Our galaxy has been consuming other glalaxies and they have been bringing their globular clusters to the feast. Way back in 1979 voyager was launched and is now almost heading out of our solar system, but believe it or not we are still in contact with the space craft. We receive regular reports from the craft about the region out where it is — 10 billion miles away from the sun.
