Today’s show features NASA’s Europa Clipper mission, which launched on October 14th, 2024 on a Falcon Heavy rocket, setting the spacecraft on its 10-year journey to explore Jupiter’s moon Europa.  Europa Clipper carries nine instruments to study this ocean world covered by an ice shell to determine if there are places in the watery depths below the surface that could support life.  The mission’s goals are to study ice shell, the sub-surface ocean, and the moon’s composition and geology.  Our guest is Dr. Bonnie Buratti, a Senior Research Scientist at the Jet Propulsion Laboratory, and Deputy Project Scientist for the Europa Clipper mission.

When people talk about going to the Moon, it is often in terms of establishing a station there, or finding water, or doing science about the Moon such as studying moon rocks.  But we can do interesting science from the Moon that can’t be done on Earth, which is our topic today with guest Dr. Jack Burns, Professor Emeritus in the University of Colorado Department of Astrophysical and Planetary Sciences and Department of Physics.  We talk about doing radio astronomy with instruments on the Moon such as ROLSES, LuSEE-Night, and FarView.

In this fire prone season, we talk with experts about an ancient building technique that might reduce the chance that a building’s going to burn. Unfired, compressed earth blocks are a building material that involves clay, sand and lime.  Our guests are architect-engineer Lisa Morey and one of her clients, Matteo Rabescini, who had such a home built in Superior, Colorado after the 2021 Marshall fire.  You can read more at Colorado Earth/Nova Terra, Heart of A Building, and Lisa Morey’s substack.

Hosts: Esther Frost, Joel Parker

In this episode, we talk with journalist and author Rebecca Boyle about her book Our Moon – How Earth’s Celestial Companion Transformed the Planet, Guided Evolution, and Made Us Who We Are. We discuss how the Moon impacts all aspects of our lives including the creation of life. It is a key component to philosophy and religion, culture and agriculture, art and science, sense of time, and sense of our place in the universe.

This is the third and final episode of a series where we hear about recent research presented at the American Astronomical Society (AAS) January 2024 meeting.

Habitable Worlds Observatory (starts at 5:15) Dr. Megan Ansdell, Program Scientist at NASA Headquarters in the Astrophysics Division and the Planetary Science Division, talks about the Habitable Worlds Observatory, a proposed mission for a large ultraviolet, optical, infrared space telescope.

Impostor Phenomenon (starts at 14:28) Jennifer Bates, a licensed clinical social worker, the Broadening Participation Program manager at the National Radio Astronomy Observatory, and the project lead for the Radio Astronomy Data Imaging and Analysis Lab discusses Imposter Phenomenon and how it affects science researchers.

This is the second episode of a series where we hear about recent research presented at the American Astronomical Society (AAS) January 2024 meeting.

3D Astronomy (starts at 3:08) Dr. Nicole Karnath, Research Scientist, at Space Science Institute, talks about using the Hubble Space Telescope and the airborne SOFIA telescope to explore the wondrous 3D world of protostellar shocks.

AI in Astrophysics (starts at 17:38) Dr. Megan Ansdell, Program Scientist at NASA Headquarters in the Astrophysics Division and the Planetary Science Division, talks about using artificial intelligence and machine learning in astrophysics research, and how AI/ML can be applied to large datasets, and the example of data that will come from the Nancy Grace Roman Space Telescope.

This is the first episode of a series where we hear about recent research presented at the American Astronomical Society (AAS) January 2024 meeting.

Magnetic Braking in Old Stars (starts at 3:13)  Dr. Travis Metcalfe from the White Dwarf Research Corporation talks about studies of one particular star, 51 Peg, that has gone through magnetic braking. He discussed how studying magnetic fields around similarly middle-aged and older stars not oly can help us in our search for life on other planets, but also provide a clue of what might have impacted the evolution of life here on Earth.

Citizen Science with Zooniverse (starts at 13:21) Dr. Laura Trouille from the Adler Planetarium is the Principal Investigator of the Zooniverse project.  She explains how “citizen science” works, which crowd-sources science research in a wide range of projects not only in astronomy, but topics ranging from biology and physics to arts and literature.
