About The Podcast

From the producer of Pulse of the Planet and the world’s most widely read astronomer -  a weekly freewheeling exploration of the astonishing world of science.  What’s the most inexplicable object in the cosmos?  When is Doomsday coming?  The heaviest thing in the universe?  Nikola Tesla’s dark secret?  All this and more, each week on Astounding Universe.  

“Jim Metzner isn’t in charge of the universe but he probably knows who is. Metzer has recently debuted his newest project, a podcast called Astounding Universe. It is a doozy.”
