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....

- Dec 13 & 14 Geminids meteor shower peak.

- Dec 14th Solar eclipse in Chile.

- Dec 21 Jupiter/Saturn conjunction.

Paul Hill, Ralph Wilkins and Jenifer Millard host. Damien Phillips and John Wildridge produce.

The Discussion:

We discuss National Geographic’s The Right Stuff series on Disney+, get a little bit rantiferous about the use of jokey, timey-wimey titles in research papers and read out a few of your emails.

The News: Rounding up the astronomy news this month we have:

- An update to the Geysers on Jupiter’s moon Europa.

- Another asteroid flies scarily close to Earth.

- The latest developments in Muskworld.

- China’s ambitious Chang’e-5 mission en-route to the moon.

Main News story: The Hayabusa 2 mission and the imminent return of samples from asteroid Ryugu.

The Sky Guide: This month we’re taking a look at the great winter constellation of Orion with a guide to its history, how to find it, a couple of deep sky objects and a round-up of the solar system views on offer in December.

Guide to the Electromagnetic Spectrum: In November we concluded our look at the electromagnetic spectrum. But as we now have a new method of detecting events beyond the electromagnetic spectrum, this month we explain gravitational wave astronomy.

Bio: Awesome Astronomy is a podcast beamed direct from an underground bunker on Mars to promote science, space and astronomy (and enslave Earth if all goes well).

It’s time for school! The Astro101 series will cover some of the most important questions in astronomy. In today’s lesson, we’ll have: What are the different kinds of stars? Why does classification in astronomy make no sense? How the heck do we define a “star”, anyway? I discuss these questions and more in today’s Ask a Spaceman!
