This week on Astronomy News with The Cosmic Companion, we welcome Dr. Cathy Olkin from the Southwest Research Institute to the show. We will talk about Lucy – the first mission to explore the Trojan asteroids of Jupiter.  But first, we look in on an unusual radio signal coming from near the center of our galaxy. Next, we journey out to the International Space Station, where a signal from a smoke alarm caused concern prior to a spacewalk. Finally, we explore the Cosmos in the most-detailed virtual universe yet created before welcoming our special guest.  Listen to the podcast version of this episode here, or watch it as a video at: https://youtu.be/0cXJIEymjnc.  Next week: Dillon Dong, graduate student at Caltech, talking about discovering a new type of supernova!  Please subscribe or follow today, and never miss an episode!--- Send in a voice message: https://anchor.fm/the-cosmic-companion/messageSupport this podcast: https://anchor.fm/the-cosmic-companion/support Get full access to The Cosmic Companion at thecosmiccompanion.substack.com/subscribe
