At the fourth Research Unplugged event of the fall season, Christopher Palma led a discussion on "Galactic Cannibals," explaining to a riveted audience how larger galaxies draw in, tear apart and "swallow" smaller galaxies that come too close to their gravitational pull.

Palma, a Senior Lecturer in the Department of Astronomy & Astrophysics and an Outreach Fellow for the Eberly College of Science, presented images of some of the most famous galactic cannibals, including our own Milky Way galaxy which is almost finished consuming the Sagittarius Dwarf galaxy.

Retracing his research steps, Palma took the audience back in time to the year 2000 when—as a graduate student at the University of Virginia—he made his own "serendipitous" discovery at the Kitt Peak National Observatory: evidence of cannibalistic activity in a galaxy called NGC 4013.

Please join us on Wednesday, November 12th for Maryann Frazier's Research Unplugged presentation, "Vanishing Bees: What is Happening to Bees and Other Pollinators?"
