Arjun Dey, PhD, Astronomer, National Optical Astronomy Observatory, Tucson, Arizona. Dr. Dey is a 2013-14 Research Fellow at the Radcliffe Institute for Advanced Research in Cambridge Massachusetts. He is an expert on galaxy evolution, high redshift galaxies, and large-scale structures in the universe. His many discoveries include one of the earliest galaxies in the universe.

In this discussion Dr. Dey describes how astrophysicists, with advanced techniques and powerful telescopes, penetrate the most remote areas of the universe, to see the early universe and the first galaxies. He describes the discovery by his team of the most remote galaxy on record. He also discusses the forces that drive galaxy formation, especially the type so massive they are hard to imagine. As astrophysicists gain better understanding about the formation of super-sized structures in the cosmos, they anticipate that their discoveries will lead to insights into dark matter and dark energy.
