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.
