Betelgeuse smaller and closer than previously thought… what?

All of Betelguese’s strange behavior for the last year had everyone looking at the star, which the latest research shows is smaller and closer than previously calculated. Plus, InSight’s mole is finally all the way underground, new measurements of atomic hydrogen in distant galaxies, and two planets have been discovered around a red dwarf star.

Death by Spaghettification!

Join us for a look at today’s top story: ESO telescopes captured the last moments of a star being destroyed by a black hole in a tidal disruption event. Plus scientists are studying Bennu’s surface to get ready for next week’s touch and go sample collection, and NOIRLab begins the process of restarting telescope operations at several observatories around the world.

Mission updates: Arecibo suffers damage, OSIRIS-Rex performs final rehearsal, TESS completes primary mission, plus guest Kynan Hughson talks Ceres

Join us today as we share some mission updates, good and bad. The bad: Arecibo Observatory suffered damage from a snapped cable. The good: OSIRIS-Rex performed a final dress rehearsal for taking a sample of Bennu and NASA’s TESS finished its primary mission. Plus, we’re joined by postdoc Kynan Hughson to talk about this week’s Ceres news!

Solar clock; Hubble constant; Universality of Free Fall; Neutron lifetime measurement; Interstellar parallax; Backyard astronomy exoplanet

Join us today as we look at six different astronomy stories. We start with a new clock of solar activity, then talk about three articles on updates to fundamental theories. We follow up with interstellar parallax observations and an exoplanet discovered through backyard astronomy.
