We also ask whether the young Sun swallowed a super-Earth, find out why a quiet Sun is bad news at thirty-five thousand feet, and watch JWST run the most sensitive exomoon search ever attempted. Plus a Crew-13 update and a skywatch with a live aurora alert for both hemispheres. In this episode · Two thousand, eight hundred and eighty-four Type Ia supernovae, rebuilt from Pantheon+ and the Dark Energy Survey's full five-year sample into a single internally consistent catalogue by Ryan Camilleri and Professor Tamara Davis at the University of Queensland, with ANU, Swinburne and international colleagues. · On their own the supernovae give a matter density of 0.310 for flat ΛCDM. Combined with the CMB and baryon acoustic oscillations, a tension appears under constant dark energy — and eases when dark energy is allowed to evolve. Preference: 2.5–3.1 sigma. · Why that is interesting but not a discovery, and why a second independent line of evidence pointing the same way as DESI changes the shape of the argument. · Professor Mutlu Yildiz (Ege University) on whether the young Sun engulfed a planet of 5–10 Earth masses — and whether that single event explains both the solar sound-speed discrepancy and the Sun's missing lithium. · Yaniv, Yair and Price on six balloon flights to 35 km: cosmic radiation at cruising altitude runs 40–60% higher at solar minimum, with an anticorrelation of r = −0.71 against solar activity. · David Kipping stacks twelve JWST transits of LP 890-9c and excludes moons down to 0.1 Earth radii across the entire Hill region — the most sensitive exomoon search on record. · Crew-13 now…","meta_description":"An Australian-led team has rebuilt thirty years of supernova observations into one consistent catalogue — and it adds fresh weight to the idea that dark e…","key_points":[],"chapters":[],"topics":[],"duration_seconds":1794,"processing_state":"not_requested","actions":[{"name":"request_transcript","method":"POST","url":"https://stenobird.com/v1/public/podcasts/astronomy-daily-space-news-updates-5658676/episodes/the-evolving-enigma-of-dark-energy-and-the-sun-s-mysterious-past/transcription-requests","description":"Idempotently request low-priority transcript generation for this episode."},{"name":"read_markdown","method":"GET","url":"https://stenobird.com/podcast/astronomy-daily-space-news-updates-5658676/the-evolving-enigma-of-dark-energy-and-the-sun-s-mysterious-past.md","description":"Read the agent-friendly Markdown representation of this episode resource."}]}}
