Looking Up

By some counts as much as 96% of everything in the universe comes from dark matter and dark energy. And, up to now, both are completely invisible. Few in the field question this theory, but could there be alternatives? Dean chats with Professor Stacy McGaugh from the Department of Astronomy at Case Western Reserve University to learn more.

What happens when 3000 astronomers gather in one place? The annual American Astronomical Society meeting puts this question to the test. In this episode, Dean Regas shares what makes a gathering like this so special, reflecting on conversations he had with like-minded astronomers at his first AAS meeting. Special thanks this episode to Diana Hannikainen, Christina Williams, Kevin Legore, Aaron Yung, Allyn Smith and Alex Thomas.

With Artemis II's recent launch, we are revisiting this conversation. Dean gets to the root of this question with guest Oliver Morton, Senior Editor for The Economist and author of the book The Moon: A History for the Future. They discuss Musk's likelihood for a Mars landing, and what the future of private space travel could mean for present Earthlings.

With the recent release of the "Project Hail Mary" film adaptation, we are revisiting a favorite episode of "Looking Up." Dean chats with science fiction novelist Andy Weir about what it takes to solve problems in the cosmos or as a stay-at-home dad. The acclaimed author of "The Martian" (which itself became an acclaimed film) also updates listeners on the eagerly anticipated film adaptation of another of Andy's books: "Project Hail Mary."

Last fall, NASA announced that it found something incredible in a rock on Mars. A core sample obtained by the Mars Perseverance rover discovered a potential biosignature. In other words, a potential sign of ancient life on Mars. Dean Regas chats with Kathryn Stack Morgan, Perseverance project scientist at the Jet Propulsion Laboratory, about this chemical "fingerprint."
