An analysis of the craters on Bennu’s surface provides evidence that the rubble pile asteroid is protected from smaller impacts by the boulders scattered on the surface. Plus, the SLS Wet Dress Rehearsal, dwarf galaxies around M81, and this week in rocket history, we look back at the X-15 hypersonic plane.
Despite being shut down a decade ago, the Collider Detector at Fermilab provided enormous amounts of data, some of which have recently been re-analyzed, leading to the discovery that the W boson is actually more massive than calculations and predictions expected. Plus, another JWST update, the newest most distant galaxy, gravitational waves, and an interview with Dr. Kelsi Singer about cryovolcanoes on Pluto.
Researchers pouring through high-resolution Hubble images of galaxy clusters have found the gravitationally magnified light of a star that was shining just four billion years after the Big Bang, making this bright star the new record holder for the farthest ever spotted. Plus, some launches, ice volcanoes on Pluto, melting Arctic ice, and this week in rocket history, we look back at INSAT.
Dr. Pamela and Beth each picked their three favorite stories from 2021, including news from Mars and Pluto and about distant comets and undead white dwarf stars. Plus, we interview Dr. Jackie Faherty from the American Museum of Natural History about citizen science, exoplanets, and JWST.
New models of sublimating nitrogen show that the process creates enough heat to drive the formation and texture of the polygons in Sputnik Planitia. Plus, black holes, star formation, and an interview with Dr. Jonathan McDowell, orbital police.
Scientists analyzed the results of a stellar occultation when Pluto passed in front of a distant star and found that Pluto’s atmosphere is freezing to the surface as the planet moves away from the Sun. Plus, an interview with Dr. Kat Volk regarding Transneptunian space and the possibility of Planet 9.
