What is 'Oumuamua? Alan Jackson & Steven Desch ASU The Cosmic Companion March 30, 2021

This week, we have a double interview, talking with astronomer Alan Jackson and astrophysicist Steven Desch. We will talk about their new study of 'Oumuamua, an interstellar body which visited our solar system in 2017.  But first, we look at some odd geology on the Red Planet, as researchers learn how spiders on Mars form. We also see new images of the supermassive black hole at the core of the galaxy M87. Finally, we dive into the mammoth oceans of Saturn's moon, Enceladus, learning how currents flow under its icy shell.Listen to the podcast of this episode here, or watch the video version of this episode at: https://youtu.be/T4Vu3n4Z3OENext week: Yuri's Night - celebrating the 60th anniversary of human spaceflight and the 40th anniversary of the Space Shuttle with three-time Shuttle astronaut Dr. Kathryn D.
