Walkabout the Galaxy

The astroquarks tell their eclipse stories from the Great American Eclipse. The Sun and every star has weather, spots, oscillations, flares and all sorts of activity. Some of this is revealed during an eclipse to the naked eye. Now, telescopes have enabled us to map the appearance of the red supergiant, Antares. Join Josh, Addie and Jim for this stellar episode of Walkabout the Galaxy.

The weight on that box of breakfast cereal ultimately traces back to "le grand K", a metal sphere in a vault in Paris, a wonderfully archaic standard for how much stuff makes a kilogram. We'll talk about the efforts to update that standard, the next Kuiper Belt Object to be explored by the New Horizons spacecraft, eclipses and occultations, and of course Zombies. Join the astroquarks for the latest astro-news, nerd news, and this episode's trivia about the length of the month!

The Sun doesn't just shine, it rings like a bell, or a drumhead wrapped into a ginormous ball of incandescent plasma. The astroquarks talk about how helioseismology tells us about the interior of the Sun, and new research shows some surprising changes in the Sun's outer layers. And the disappointing news from the realm of cosmology is that dark matter is probably not warm and fuzzy, depriving us of endless opportunities for jokes, not to mention that it would be awesome if we had fuzzy dark matter throughout the universe. Catch up on the latest astronomy, nerd news, and space trivia with the astroquarks on this episode of Walkabout the Galaxy.
