As the two galaxies smash together, billions of stars are born, mostly in groups and clusters of stars. The brightest and most compact of these are called super star clusters.

At the American Astronomers Society (AAS) meeting in January 2010 Julie Comerford from the University of California, Berkely presented her work on dancing black holes. By looking at their constant movements more information about the relationship between the black holes is revealed. Julie writes about it her self in Cosmic Matters. But, this is good, Astrocast.TV's Carolyn Collins Peterson includes a great interview with the black holes experts in her The Astronomer's Universe program from the AAS meeting. You can hear and see for yourself in the video (14:31 min) below.
