The Moon in Five Hours

For fifty years the story has been that the Moon assembled slowly out of a disc of debris. New simulations from Southwest Research Institute add one thing everybody left out — the strength of rock — and get an intact Moon in about five hours. Plus eight black holes that outgrew their galaxies, two massive stars that fell past each other and got caught, Dragonfly's Titan landing site gets a name, and today's daylight occultation of Jupiter.Links & sources Southwest Research Institute — SwRI-led modeling identifies new scenarios for Moon formation — https://www.swri.org/newsroom/press-releases/swri-led-modeling-identifies-new-scenarios-moon-formation Denton, Canup, Asphaug et al. — The Astrophysical Journal Letters (DOI) — https://doi.org/10.3847/2041-8213/ae91e9 Space.com — Earth's moon could have formed in just 5 hours after giant impact — https://www.space.com/astronomy/moon/earths-moon-could-have-formed-in-just-5-hours-after-giant-impact Buchner et al. — A large population of overmassive black hole quasars at z=0.3–0.8 revealed by eROSITA, A&A 713, A11 — https://www.aanda.org/articles/aa/full_html/2026/09/aa59356-26/aa59356-26.html Astronomy & Astrophysics — 2026 press releases — https://www.aanda.org/2026-press-releases Zhang, Garay et al. — An eccentric massive protobinary assembled via a core-merger parabolic encounter, Nature Astronomy — https://www.nature.com/natastron/articles?year=2026 Universidad de Chile coverage of the IRAS 07299-1651 result — https://www.radiofestival.cl/la-danza-nupcial-de-estrellas-masivas-astronomo-de-la-universidad-de-chile-participa-de-historico-hallazgo/ NASA / APL — Dragonfly Gets Wired Up While Titan Landing Area Is Named — https://science.nasa.gov/blogs/dragonfly/2026/09/02/nasas-dragonfly-gets-wired-up-while-titan-landing-area-is-named/ Sky & Telescope — Tuesday's daytime Jupiter occultation, a warm-up for the 'big one' — https://skyandtelescope.org/astronomy-news/tuesdays-daytime-jupiter-occultation-a-warm-up-for-the-big-one/ Universe Today — September's lunar occultations: circumstances and visibility — https://www.universetoday.com/articles/penultimate-lunar-occultations-inbound-for-jupiter-venus-and-more-in-september NASA — What's Up: September 2026 skywatching tips — https://science.nasa.gov/solar-system/skywatching/whats-up-september-2026-skywatching-tips-from-nasa/ EarthSky — Visible planets and night sky guide for September — https://earthsky.org/astronomy-essentials/visible-planets-tonight-mars-jupiter-venus-saturn-mercury/Become a supporter of this podcast: https://www.spreaker.com/podcast/astronomy-daily-latest-space-news--5648921/support.Sponsor Details:Ensure your online privacy by using NordVPN.
