Dr. Mercedes Richards is a professor of astronomy and astrophysics at the Penn State University.

She is noted for studying close pairs of stars, called interacting binaries, which are pairs of stars that areĀ formed at the same time, like twins, but in which each star matures at different rates and affects the evolution of its companion.

In this brief clip, Dr. Richards talks about other habitable planets that humans can possibly live on.
