This week, join us for a special live episode from the 2024 IAU General Assembly in Cape Town, South Africa, featuring black hole simulations expert Dr. Nicole Thomas and winner of the 2011 Nobel Prize for Physics Prof. Brian Schmidt.

Cape Town born Dr. Nicole Thomas returns to The Cosmic Savannah four years after previously featuring in episodes 9 and 14 as a PhD student. She shares with us the story of her illustrious academic career around the world since then, including a postdoctoral research position in the UK at the Institute of Computational Cosmology, University of Durham and now a prestigious Jim Buckee Fellowship at the International Centre for Radio Astronomy Research, University of Western Australia.

Nicole explains to us her latest research on using state-of-the-art supercomputer simulations to understanding the havoc that supermassive black holes wreak on galaxies. She does this by trying to model how the Universe works using our current understanding of physics and comparing her results to images of the real Universe taken with South Africa's MeerKAT telescope. She hints that she looks forward to applying these simulations to the findings of the upcoming SKA telescope!

Next, Nobel Laureate Prof Brian Schmidt, a Distinguished Professor at the Australian National University joins the team on stage. Brian takes us back to the night of the 4th of October 2011 when he received a call from Sweden telling him he had won the Nobel Prize. Brian received the prize, alongside two other people, for having discovered the accelerating expansion of the Universe. He discusses what life has been like after such a monumental achievement, including his experiences as Vice-Chancellor of the Australian National University. Finally, he tells us about his plans to get back to doing research and reveals what he thinks the next big astrophysical breakthroughs will be using the SKA telescope under construction in South Africa and Australia.

A luminous black hole already classified as an active galactic nucleus brightened suddenly in recent ground and space observations, and the cause may be due to a sudden flip in the magnetic poles. Plus, community science, rockets, Ingenuity, and an interview with Dr. Cathy Weitz from Planetary Science Institute.

Streamed live on Nov 8, 2025.

With the arrival of the comet 3I/Atlas (Asteroid Terrestrial-impact Last Alert System), the world is getting a crash course in comets, their behavior, and of course their tails. Today we're going to talk about comets and their tails, why they exist, how they grow, why they can be different colors and how they can be sometimes point AT the Sun.

Comets are one of the most animated and ephemeral targets for astronomy. From night to night they can change in shape and color, and every nuance tells us something. In this episode, we decode blue tails, green cores, forward-facing plumes, and other weird and awesome details observed with these icy visitors.

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

From August 2025.

Today's 2 topics:

- The Trappist-1 planetary system located about 40 light years away in the constellation of Aquarius consists of a small red dwarf star and 7 Earth sized planets. By carefully studying changes in the planet's transit timings and the shape of the dip in the host star's brightness as each planet transits across it, astronomers have been able to measure the orbital period, radius, and approximate mass for each of the 7 planets.

- Recently my Catalina Sky Survey teammate Richard Kowalski discovered 2017 MB1, a 0.4 mile diameter asteroid with the Catalina Sky Survey Schmidt telescope on Mt. Bigelow, AZ. Two hours and 11 minutes later it came into a set images I obtained with the 60 inch telescope on Mt. Lemmon, AZ. After I reported it, the new object was tracked by telescopes in Arizona, New Zealand, Slovenia, Kansas, Australia, Hungary, France, and Brazil.
