Astronomy News with The Cosmic Companion. This week, we are delighted to be joined by one of the world's most renowned oceanographers, Dr. Sylvia Earle. She's here to talk to us about her new book, National Geographic Ocean | A Global Odyssey. We're going to get an in-depth look at the oceans of our home world.We're also going to take a look up in the sky, as a trio of planets line up with the Moon, and the Geminid meteor shower aims to delight skygazers.
