Astronomy Daily S05E154 — “The Reach of a Giant.” Thursday, 30 July 2026. Hosted by Anna and Avery. In this episode • A supermassive black hole caught heating and stirring an entire galaxy cluster — turbulence reaching ~300,000 light-years, about 100× more energetic than expected (XRISM / quasar H1821+643). • Why some “clean” white dwarfs are secretly feasting: magnetic fields funnel shredded planetary debris to the poles, aurora-style, hiding the meal. • NASA’s Psyche used its Mars flyby as a dress rehearsal — spotting Phobos and Deimos from afar to practise for its 2029 moonlet hunt at asteroid 16 Psyche. • A new study on keeping the road to the Moon clear: modelling how debris disperses in Distant Retrograde Orbits as cislunar traffic climbs. • Skywatch: tonight’s double meteor shower — the Southern Delta Aquariids and Alpha Capricornids — with both-hemispheres viewing details and local times.

Correction / caveat desk • Skywatch numbers assume the ~98% waning Buck Moon (full 29 Jul). Faint Delta Aquariids will be washed out; the Alpha Capricornid fireballs are the reliable catch tonight.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.
