  • Crazy Spinners in the Asteroid Belt and S8 Tension

    Crazy Spinners in the Asteroid Belt and S8 Tension
    Jan 14 2026

    The amazing discoveries from the Vera C. Rubin Observatory have already started, and the astroquarks take a look at some close to home. Asteroids bigger than a city block spinning in fewer than 5 minutes are just the beginning, and will change our understanding of the collisional evolution of the asteroid belt. The astroquarks muse on the biggest questions in astronomy today, and one of those, the so-called "S8 Tension" has a possible solution with the help of dark matter and neutrinos. Join us for all that, space news, trivia, and more.
