Walkabout the Galaxy

The astroquarks are wrapped up with the passage of time and the aging of the stars, the universe, and themselves as the first annual year of the astroquark comes to a close. We discuss the red giant star Betelgeuse's mysterious year-end fainting (as in the opposite of brightening), and ss this stellar neighbor nears its explosive end, we take a look at the lives of galaxies and the universe as a whole.

Find out why, and catch up on nerd news, space news, and special Top quark astro-historical-paradoxical trivia on this episode of Walkabout the Galaxy.
