Looking Up

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."

What is a moonbow, and what does it take to get a picture of one? And do rare events in the night sky lose their appeal after you've seen a bunch of them? Dean chats with Jeff Pfaller, astro-photographer and author of "Dark Skies: Rare Phenomena in America’s Public Lands" to learn more.

How do you eat in space? Simple everyday chores like sleeping or going to the bathroom take on all new challenges when you're weightless and floating in mid-air. Dean is joined by Mark Borison, Host of The Jungle Jims Podcast to do a space food taste test.

The universe is enormous and time to observe it is limited. This means planet-hunters have to be extra picky in their search for habitable worlds. Dean chats with Dr. Néstor Espinoza, an astronomer at the Space Telescope Science Institute who has his eye on one specific star system, Trappist-1.

Revisiting a favorite from 2025: Dean chats with Inspiration4 astronaut and artist, Dr. Sian Proctor about seeing Earth from outer space, and her book, "Earthlight, The Power of Earthlight and the Human Perspective."Send us your thoughts at lookingup@wvxu.org or post them on social media using #lookinguppodcastFind Us Online: Twitter: @lookinguppod @deanregas, Instagram: @917wvxu @deanregas, Tiktok: @cincinnatipublicradio @astronomerdean, Episode transcript: www.wvxu.org/podcast/looking-up, More from Dean: www.astrodean.com

Venus is close-by and similar in size to Earth, but until recently, we couldn’t tell much about it. Dr. Rakesh Mogul, Professor of Chemistry and Biochemistry, at Cal Poly Pomona took another look at old Venus data to potentially change what we know about our sister planet. Dean chats with Dr. Mogul to unravel the mystery.

After NASA's recent milestone of over 6000 exoplanets tracked, Dean Regas has one big question. Is anyone living on them? On this episode, Dean chats with Dr. Malena Rice, a planetary astrophysicist and assistant professor in the Yale Department of Astronomy, to find out.

Dr. Konstantin Batygin, professor of Planetary Science at Caltech, made a joke that turned out to be true. In 2014, another Caltech professor, Mike Brown, brought an intriguing research paper to Batygin's attention. The paper described a peculiar planetary alignment in the outer solar system. While developing theoretical models to explain the paper's assertions, Brown and Batygin had a running gag, "We were like, okay, as a joke, let's put a planet in the outer solar system just to see what would happen." In this episode of Looking Up, Dean Regas chats with Dr. Batygin and gets the full story.

"Some people hustle pool, some people hustle cars, but have you ever heard of the man who hustles stars?" From 1976 to 1997, these lines began every episode of Jack Horkheimer: Star Hustler, the astronomy show from WPBT, South Florida PBS. Later on Star Hustler was rebranded to Star Gazers, and hosts Dean Regas and James Albury took over after Horkheimer's passing. In this episode of Looking Up, Dean and James reminisce on production of the show, plus, "buzzkill" astronomy is back!

Science journalist Anne Saker describes the Chandrasekhar Limit as a range of possibility where if a planet has enough stability in its magnetic force and its gravitational force, it can sustain life. This Nobel Prize winning discovery changed the field of fluid dynamics. Though it was named after theoretical physicist Dr. Subrahmanyan Chandrasekhar, he credited his computer, Donna Elbert, "for without her part, there would have been no substance.” Dean Regas chats with Anne Saker to learn more about Donna Elbert's astronomical legacy.
