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.
