    Repainted Rose, Worlds Colliding, and White Dwarfs of Unusual Size

    This week we look at the weird results in space science. From looking at how wildly different images from different IR telescopes can be colorized, to worlds colliding, to white dwarfs of unusual size ,and even to Earth's crust on the move, the news was surprising and sometimes a tad bit horrifying. And we present all of it here.

    No Good, Very Bad News and Some Planetary Palate Cleansers

    Join us as we bounce between the geology behind the recent landslide in Nepal and Tibet, the joy of Saturn's south pole forming a decagon, the frustration of both US and Russian space programs having launch capacity issues, and the good news of BepiColombo getting ready to enter Mercury's orbit.

    After Hours: Making Moons and Getting Cratered with William K Hartmann

    Across a long career, Dr William Hartmann has done everything from innovating how the Moon was formed to founding the Planetary Science Institute to defining space art for a new generation; a generation that included host Pamela Gay. Tune in to hear about science, art, and how they can mix as individuals both make new discoveries, and the illustrations to accompany them!

    After Hours: Doing Big Science with Light Tools with guest Dr Danny Jacobs

    Science comes from many corners, and there is a need for both 600-m radio telescopes made on a great plain (Like the RATAN-600) and 60cm radio dishes built in a living room. In this After Hours, we talk with ASU professor Danny Jacobs about how he engages students of all kinds in space sciences through educational tools like the cardboard radio telescope (https://astrochart.github.io), and in space telescope operations with the SPARCS small sat (https://sparcs.asu.edu/)

    After Hours: International Moon Day 2026 with guest Jekan Thanga

    On July 20, the world celebrates International Moon Day. This UN designated holiday marks the anniversary of humanity's first landing on the Moon. The Apollo 11 landing in 1969 is now only a distant memory or a date from history for most people, but it is worth thinking about as the world prepares to return humans to the Moon in the coming decade. Joining us to discuss International Moon Day is Dr. Jekan Thanga, the head of the Space TREx Laboratory at the University of Arizona. Come learn how his interdiciplinary team is taking a page from the past as we plan for a Lunar future.

    After Hours: Space Rocks Collected for Science with guest Dr Rhonda Stroud

    Our solar system readily provides us with free samples of other worlds in the form of meteorites. The trick comes in first recognizing them, and then in understanding what science is locked in their minerals. One major center for collecting and studying these space rocks is Arizona State University's Buseck Center for Meteorite Studies which houses the Carleton B Moore Meteorite Collection. Join us as we discuss the collection with Director Rhonda Stroud.

    Tracing the hidden and revealing the past

    In this episode we look at the hidden and unexpected geology that may lurk beneath East Antarctica's ice sheet, evidence of past worlds and lost moons that may once have populated our solar system, and evidence of a past Supernova that today may be showering the Earth with material.

    After Hours: Our shape shifting Universe with author Chanda Prescod-Weinstein

    Join Pamela for an hour that looks at science and society as she talks with author and cosmologist Chanda Prescod-Weinstein. In her new book, "The Edge of Space-Time: Particles, Poetry, & the Cosmic Dream Boogie" Prescod-Weinstein weaves scientific and lyrical understandings of cosmology, bringing together the language of elders with the math of modern computational models. This combination puts our human state in a greater perspective of time and space that looks beyond western textbooks (Oh, and there is a lot of Star Trek referenced in there too!)

    After Hours: Launching the small(er) things with Exolaunch CEO Robert Sproles

    As commercial space becomes a more and more mature industry, we're seeing new needs emerge. Front and the center is the need for someone - or some company - to make it easy for folks in need of a launch to find the right ride share for their satellite, no matter how small. Enter ExoLaunch. In this episode we talk with ExoLaunch CEO Robert Sproles about what their company is accomplishing as the shipping company to the stars (or at least Earth Orbit).
