CK Vul was first observed hundreds of years ago and thought to be a nova. Modern observations have called this into question. In this podcast, Tom Geballe tells us about recent observations with the Gemini International Observatory which deepen the mystery of CK Vul.

Bio: Rob Sparks is in the Communications, Education and Engagement group at NSF’s NOIRLab.

Tom Geballe is retired from the Gemini International Observatory and he is still an active researcher.

Host: Fraser Cain ( @fcain )
Special Guest: We are pleased to once again welcome Casey Dreier from the Planetary Society to the WSH. Casey will update us (as much as possible) about Space Policy changes that may occur once the new American Presidential administration takes office on January 20, 2021.

As Chief Advocate, Casey is the public face of The Planetary Society's efforts to advance planetary exploration, planetary defense, and the search for life. He educates and empowers the organization's members to take political action. He writes, teaches, and speaks to The Society's members, the public, and policymakers to impress upon them the importance, relevancy, and excitement of space exploration.

Casey is committed to demystifying the politics and policy process behind space exploration for all audiences. He is a trusted source for journalists and has been featured in many publications, including The New York Times, The Washington Post, The Atlantic, Scientific American, Vox, and The Verge, to name a few. He also has appeared as an expert on BBC News and both seasons of National Geographic's MARS series as a "MARS Big Thinker".

As Senior Space Policy Adviser Casey helps lead the strategic planning of The Society's policy and advocacy efforts. He works closely with The Society's leadership, its Board of Directors, and other policy experts to craft the organizational positions and goals regarding the future of space exploration. He provides trusted analysis of the budgetary, political, and policy decisions relating to space, pursues original research, and works collaboratively to generate policy ideas and guidance for the U.S. space program.

Casey is a regular contributor to The Planetary Report, co-hosts the monthly Space Policy Edition podcast of Planetary Radio, and regularly publishes space policy analysis and insights on planetary.org.

Be sure to tune in to Planetary Radio: Space Policy Edition (https://www.planetary.org/planetary-r...) to stay up to date with space policy around the world.

Once again, we find that dust is the culprit, this time causing a black hole to cast shadows out from the heart of its galaxy. Plus, a megaflood on ancient Mars, a fossil galaxy in the Milky Way, another minimoon for Earth, newborn jets and more.

– What’s the latest with the James Webb Space Telescope?

Alas the James Webb Space Telescope is becoming a tale of woe. There were high hopes of maintaining its 2018 launch date, up until around September 2017 – when the launch date was shifted to 2019, then it was shifted to 2020.

– Who will make it back to the Moon first?

So, which nation will land a human back on the Moon first? It’s still looking like the US, since they really are building the Space Launch System and the Orion spacecraft.

So the Moon is about to become a very busy place with multiple countries and private companies planning missions in the next few years. It's been decades since the Outer Space Treaty was negotiated. It's time for the Artemis Accords!

Dr. Al Grauer hosts. Dr. Albert D. Grauer ( @Nmcanopus ) is an observational asteroid hunting astronomer. Dr. Grauer retired from the University of Arkansas at Little Rock in 2006. travelersinthenight.org

Today's 2 topics:

- Some months the asteroid hunting community finds more than a half dozen small asteroids that pass closer to the Earth than our Moon.

- A small previously unknown asteroid immediately got my attention. I was observing with the NASA funded, University of Arizona, Catalina Sky Survey, 60 inch telescope, on Mt. Lemmon.

We apologize for the audio quality issues this month. It seems the noise limiting function is introducing more noise than it's limiting!

CONJUNCTION MONTH! If there’s nothing else you do this month, mark your calendar, get your warm clothes set aside, and get ready for a very, very rare conjunction between Jupiter and Saturn on the 21st.  More details to come.  If you do more than that one thing, we also have another meteor shower and some good close encounters between the Moon and the planets.

Host: Fraser Cain ( @fcain )
Special Guest: This week we are joined by Dr. Ingrid Daubar, Planetary Scientist from Brown University studying impact cratering within our solar system. Dr. Daubar is part of a team that has been using a new AI classification tool to identify geologic features on planetary surfaces, such as Mars.

Ingrid has been involved in planetary science for more than two decades. Her research interests include impact craters and other time-varying phenomena on terrestrial planets. She has participated in science and operations on multiple missions including MRO, InSight, Europa Clipper, and Juno.

Dr. Daubar’s research on small, recent impact craters on Mars and the Moon has allowed us to better understand the impact flux in the inner solar system, the chronology of recent events and timescales of geologic processes on these bodies, and the processes involved in modern-day cratering and modification over time of planetary surfaces.

You can learn more about Ingrid by visiting https://vivo.brown.edu/display/idauba....
