This episode, it's Jen and a special guest exploring the inexplicable Big Ring, the first proof connecting supernovae to black holes and neutron stars, cyclones on a far-away world, dazzling images of Io, and the true colour of Neptune. We also take a deep dive into humanity's efforts to explore the Moon – the failing Peregrine lander and Artemis pushbacks. There's also a sky guide for the second half of January, and our discussion topic this time involves a most impossible restaurant.

Produced by Paul, Jen, Dustin, John & Damien.
