Spacebook - Look Up! November 2016

Royal Observatory Astronomers Radmila and Dhara take you through what to see in the night sky during the month of November in our family friendly Look Up! podcast.

This month they talk about the recent discovery that there may be ten times more galaxies in the Universe than originally thought, bringing the estimated number to 2 trillion. Plus they explain why the number density of galaxies had dropped over billions of years.
