Is This How We Get Cylons?

In this show, we’ll go through more than 20 studies and observations ranging from planetary climates to galaxy mergers, and we’ll take a closer look at how Artificial Intelligence is being asked to play a role in every area of this research. And we’ll ask, “Is this how we get Cylons?” (This episode originally aired on television February 18, 2023)

Cosmology: From Particles to Galaxy Clusters

We live at a time when technological advances are allowing us to explore ideas faster than ever before. So today, we bring you lab results on ice that affect how we see the outer solar system, and observations of galaxies that affect our understanding of the universe’s formation. We go from things smaller than a proton – which we just learned is 0.73 femtometers across -- to galaxy clusters 10s of millions of lightyears across. It’s all tied together, and we’ll tell you how.

Mass Extinction, Volcanoes, and Rings Around an Asteroid

In this episode, we discuss one mass extinction, three stories with volcanoes, star formation, galaxy dissolution, and space mission synchronized observing. We also take a closer look at dark energy and dark matter and how giant galaxies in the early universe seem to indicate we may know even less than we thought. And rockets. There are always more rockets thanks to SpaceX. (This episode originally aired on television February 4, 2023)

Space science potpourri and a more hopeful look at climate change

This episode has a little bit of everything as we bring you results from astronomers, geoscientists, climate scientists, imaging scientists, glaciologists, meteorologists, planetary scientists, engineers, and even bioarchaeologists. This diversity of research allows us to better understand our world and beyond. In our first segment, we look at how our ecosystem and past cultures rebounded after prior naturally occurring climate events. It's unclear if this research will help us better recover fr...

JAXA Triggers Flight Termination of Launch

Space is hard, and some days, getting rockets to work doesn’t go as well as expected. An Epsilon rocket launched by JAXA and carrying eight payloads including RAISE 3 was lost when mission control triggered the flight termination system due to an attitude issue. Plus, stars blowing dust rings, stars exploding, asteroids getting hit with spacecraft, and Europa’s geysers may not come from the subsurface ocean.

Dinosaurs Washed Away in Largest Wave to Wrap Earth

As if getting set on fire and tossed into space wasn’t enough, new research finds evidence that after the Chicxulub impact, dinosaurs were also the victims of a massive global tsunami and worldwide earthquakes. Plus, the Milky Way’s stellar graveyard, a new timeline for the Moon’s formation, and this week in space history, we look back at the Meteosat program.

Observed: It’s a Star-Eat-Star Universe

While astronomers have observed white dwarfs consuming companion stars on numerous occasions, for the first time, they have now observed the consumption of the companion’s helium and not just hydrogen. Plus, galactic alignment, rocket launches including Crew 5, a new Europa image, and a review of the video game “Tinykin”.

Globular Clusters: Already Old Nine Billion Years Ago

The quest to understand the formation mechanisms of globular clusters was limited by the Hubble Space Telescope’s ability to peer back in time. Now, JWST’s larger mirror has allowed astronomers to find gravitationally lensed galaxies that have globular clusters almost nine billion years old. Plus, two new super-mercury exoplanets, This Week in Space History, and an interview with Eric Palmer about the DART mission.

DART Mission Successfully Boops Dimorphos

After ten months of space travel, NASA’s DART spacecraft arrived at the asteroid Didymos, targeted the moonlet Dimorphos, and successfully flung itself at the surface. Multiple observations confirm that the system brightened and even managed to resolve a cloud of debris. Plus, rocket launches, an update on the SLS, some broken physics, and International Observe the Moon Night.
