This week, we talk to Dr. Lauren Weiss, astronomer at the University of Hawaii. We will be talking about her work discovering the TOI-561 planetary system, and discussing extreme exoplanets!But first, we head out to the TRAPPIST-1 solar system, where we find each of the seven worlds in that system are surprisingly alike. Next, we look at a new study finding that earlier reports of phosphine on Venus may have been in error. Then, we look at a new conceptual idea for a next-generation plasma engine that could bring spacecraft and people to Mars and beyond.Listen to the podcast episode here, or watch it in video: https://youtu.be/r_QFsXew_Vs --- 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
