S05E158 — “The Crater Makers” · Tuesday 4 August 2026. Four stories on cosmic impacts — and a new map of the X-ray sky — plus a both-hemispheres skywatch. ① A dead Falcon 9 is about to crater the Moon ● A spent SpaceX Falcon 9 upper stage (catalogued 2025-010D) is predicted to strike the Moon near Einstein Crater on 5 Aug 2026 at ~06:35 UTC — the second documented uncontrolled rocket impact on the Moon. ● The stage launched Firefly’s Blue Ghost and ispace’s Resilience landers in Jan 2025, then was stranded in a chaotic Earth orbit for ~18 months. Impact speed ~2.4 km/s (~5,400 mph); expected crater ~17–27 m across. ● Prediction by Bill Gray (Project Pluto). NASA’s LRO can image the site before and after; a ~two-dozen-author campaign is coordinating observers to chase the ejecta plume. ● Governance angle: no international framework governs cislunar debris — a growing hazard as lunar traffic increases (callback to E154’s distant-retrograde-orbit debris study). Sources: Space.com / Forbes / Reuters (Cris Tolomia) — impact preview, 31 Jul–3 Aug 2026 · Project Pluto (Bill Gray) — 2025-010D impact page · ZME Science — impact timing, 3 Aug 2026 ② Neptune’s inner moons: shrapnel of a shattered world ● JWST NIRSpec spectroscopy of Neptune’s inner moons Larissa, Galatea and Proteus (Caltech; lead author Ryleigh Davis, Mike Brown’s group) detected magnesium-rich phyllosilicates — clay minerals that require liquid water and had never been seen beyond Jupiter. ● The clays imply the material came from much larger, water-bearing worlds — evidence that Neptune’s original regular moon system was destroyed when Triton (a captured Kuiper Belt object) arrived. ● Proteus, the largest of the three, lacks the clays — possibly re-heated and reprocessed after re-forming, hiding its history. Sources: Davis et al., Science Advances, 29 July 2026 · Caltech / phys.org press coverage, 29 Jul–3 Aug 2026 · Space.com (Charles Q. Choi), 3 Aug 2026 ③ “Charbroiled within hours”: impact dust and the dinosaurs ● New modelling (Brandon Johnson et al., Purdue) argues ultrafine impact dust from Chicxulub acted as an insulating blanket, raising surface heating ~3.5× above the spherule-only estimate — enough to ignite global wildfires and kill exposed animals within hours. ● The same dust then blocked sunlight for years — so the model adds a ferocious opening act to the established “impact winter,” rather than replacing it. Sheltering underground or underwater aided survival. ● Caveat: the strongest physical wildfire evidence is so far confined to North America (per UCL’s Alfio Chiarenza, not involved in the study); a truly global fire record remains unconfirmed. Sources: Johnson, Johnson, Wakita & Robertson, JGR: Biogeosciences, 2026 · Popular Science / Space.com / ZME Science, 28 Jul–2 Aug 2026 ④ eROSITA DR2 — the X-ray sky doubles ● The eROSITA telescope (SRG mission) released its second data set (DR2) on 31 July 2026: ~1.9 million pointlike and ~64,000 extended X-ray sources from the first three all-sky scans — nearly doubling the previously released eROSITA catalogue. ● For scale: ROSAT catalogued ~130,000 sources in the 1990s and was the benchmark for 30 years. Lead author: Miriam Ramos-Ceja (MPE). ● DR2 delivers the first direct census of cataclysmic-variable binaries sufficient to explain the decades-old Galactic Ridge X-ray Emission. It coincides with SDSS DR20 (Black Hole Mapper), enabling 3D mapping of active black holes. Sources: Ramos-Ceja et al. (eROSITA-DE), arXiv:2607.27772; DR2 release · Max Planck Society press release, 29 July 2026 · phys.org, 31 Jul 2026 Skywatch — both hemispheres ● Falcon 9 impact (5 Aug, ~06:35 UTC): not naked-eye; ejecta plume a long shot for advanced amateurs in the Americas near the western limb (~2:35 a.m. EDT). Sydney: Moon below horizon — watch for LRO after-images. ● Comet 10P/Tempel 2: perihelion 2 Aug, closest to Earth 3 Aug (~0.41 AU); ~mag 8–9 near M30 in Capricornus. Best return of the century; Southern-Hemisphere-favoured; Northern viewers low on the southern horizon. Darkest window ~7–8 Aug. ● This evening: Venus threads between Regulus (Leo) and Spica (Virgo) in the west — both hemispheres, no equipment. Mercury at its best morning showing (greatest western elongation 2 Aug), low in the pre-dawn east. ● Diary — 12 Aug: total solar eclipse (Greenland/Iceland/Spain), moonless Perseid peak, six-planet alignment. Always use certified ISO 12312-2 eclipse glasses / solar filters except during totality.

Astronomy Daily · S05E157 · “The Edge of Everything” · Monday 3 August 2026 In this episode • The largest galaxy, measured at last. Ultra-deep imaging of IC 1101 in the Abell 2029 cluster has traced its outer edge for the first time: an edge radius of ~260 kpc, a diameter near 520 kpc (~1.7 million light-years), and ~3.4 trillion solar masses in stars — about 17× the width of the Milky Way. Faint outer structures aligned with cluster X-ray disturbances show it is still accreting. Source: Marrero-de la Rosa et al., “How large can galaxies be? Ultra-deep imaging of IC 1101”, accepted A&A (arXiv:2607.15340, 16 Jul 2026); phys.org, 31 Jul 2026; The Debrief, 1 Aug 2026. • Hayabusa2's record asteroid flyby. JAXA confirmed (press conference 30 Jul) that its Hayabusa2 probe passed just 400 m from the surface of near-Earth asteroid Torifune on 5 July — 744 m from centre at 18,000 km/h — the closest asteroid flyby by any mission, plus the first-ever laser ranging of an asteroid during a flyby. Torifune proved to be a contact binary. Source: JAXA press conference, 30 Jul 2026; phys.org / Japan Today (AFP), 31 Jul 2026; autoevolution, 1 Aug 2026. • UK's first orbital launch on hold. Rocket Factory Augsburg de-stacked its RFA One at SaxaVord Spaceport (Unst, Shetland) after finding a vehicle issue during hot-fire test prep (announced 28 Jul). The certified launch window opens 10 August; a successful flight would be the first orbital launch from UK soil. Source: RFA statement (X), 28 Jul 2026; Space.com, 1 Aug 2026; Shetland Times, 28 Jul 2026. • Andromeda is winding down. A new Hubble study mapping ~200 million stars across two-thirds of Andromeda's disk finds star formation has declined over ~500 million years (from ~1 to ~0.2 solar masses/year), with the steepest drop in the last 40 million years — possibly linked to an interaction with satellite galaxy M32. Source: Williams et al., The Astrophysical Journal, 27 Jul 2026; NASA/STScI release, 27 Jul 2026. Skywatch — both hemispheres • Comet 10P/Tempel 2 — perihelion 2 Aug; closest approach to Earth tonight (3 Aug). Binoculars/small scope, dark skies. Best pre-dawn from the Southern Hemisphere; ~9:30–10:30 pm local for mid-northern latitudes before moonrise. • Moon near Saturn tonight (3 Aug) — naked-eye pairing, both hemispheres, up into dawn. • Mercury at greatest western elongation (2 Aug) — low eastern horizon ~1 hr before sunrise, toward Gemini; Mars higher. Better placed for northern observers. • Diary (2 days out): Falcon 9 upper stage (2025-010D) lunar impact near Einstein Crater, 5 Aug ~06:35 UTC — ~2:35 am EDT / 11:35 pm PDT (4 Aug); North America best-timed on the dark limb.

S05E155 · Friday 31 July 2026 · Astronomy Daily with Anna & Avery. Four stories and a both-hemispheres skywatch. Australian English. ① Asteroid (44) Nysa — the first three-lobed world, and its hidden moon ● trilobate body — three lobes joined by two narrow necks; a candidate “first” of its kind. ● A new ~1 km moon, S/2026 (44) 1, was found orbiting ≥170 km out — spotted using high-contrast imaging borrowed from exoplanet work, and confirmed moving across two observing runs. ● The moon lets astronomers weigh Nysa (mass → density), which should help decide between a genuine contact-trinary and a single, deeply indented body. ● Nysa is a bright, main-belt E-type (enstatite-rich) asteroid, ~75 km across, known since 1857. ● Source: Lowell Observatory / University of Arizona press release, 29 Jul 2026; study “Unmasking (44) Nysa: Evidence for a Trilobate Structure” (Minker et al.). Coverage: Space.com, Gizmodo, 29–30 Jul 2026. ② Mapping Alien Continents — a NASA concept to image an exoplanet’s surface ● NASA’s 2026 NIAC round funds 18 early-stage “visionary” concepts (~$175k each, 9 months). These are seed studies, not missions. ● Paul Stankus (Brookhaven) proposes “Mapping Alien Continents”: resolve the surface of an Earth-like exoplanet — continents, oceans — in visible light. ● Method: a novel “dynamic hierarchical nulling” interferometer to suppress starlight at 10¹⁰-to-1 contrast, then combine beams from two spacecraft ~100 km apart (optical VLBI-style imaging). ● Source: NASA “2026 Innovative Technology Concepts” release and NIAC selections (posted 21 Jul; consolidated release ~29 Jul 2026); Universe Today feature, 30 Jul 2026. ③ Solar-storm watch — CMEs inbound, minor-storm and aurora potential ● Two faint coronal mass ejections, plus coronal-hole solar wind, are set to give Earth glancing blows; forecasters flag possible G1 (minor) geomagnetic storms and auroras over the coming days. ● G1 means little grid impact but aurora visible at somewhat lower latitudes than usual — see the skywatch for where to look, both hemispheres. ● Source: NOAA SWPC (WSA-ENLIL model); EarthSky / The Sun Today, 30 Jul 2026. ④ ESCAPADE’s family portrait of Earth and the Moon ● NASA’s twin Mars orbiters (“Blue” and “Gold,” built by Rocket Lab) imaged Earth and the Moon as thin crescents in visible and thermal-infrared light from a loiter orbit near Sun–Earth L2. ● In infrared, Earth’s night side glows with its own heat; the Moon’s shadowed half is far colder — a calibration check before Mars. ● ESCAPADE’s science goal (arrival Sept 2027): measure how the solar wind strips Mars’s unshielded atmosphere — the payoff of today’s solar-wind thread. ● Source: NASA (Goddard) image feature, ~25 Jul 2026 (images captured 3 Jul); NAU / phys.org; Universe Today, 29 Jul 2026. Skywatch — both hemispheres ● Bright waning-gibbous Moon (post-Buck-Moon, 29 Jul) washes out faint targets. ● Southern Delta Aquariids + Alpha Capricornids just past peak (SH-favoured; Moon-hampered). Perseids build to a near-moonless peak on the night of 12–13 Aug — prime for North America, low in the north for the SH. ● 12 Aug total solar eclipse: totality across Greenland / Iceland / Spain; partial for parts of northern North America and Europe. ISO 12312-2 eye protection required for any partial phase. ● Pre-dawn planets low in the east (Sydney and North American framing). Aurora watch for high latitudes both hemispheres if the storms land. ● Diary: a spent Falcon 9 upper stage (2025-010D) is predicted to hit the Moon near Einstein Crater on 5 Aug 2026, ~06:35 UTC (~2:34 a.m. ET). North America best-timed; telescope needed, Moon ~56% lit, target the limb dust plume. From Sydney the Moon is down at impact — rely on LRO after-images. Callback to E125/E147.

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. Sources • Yamada, S. et al., “Vigorous turbulence driven by quasar-mode feedback in a cluster core,” Nature Astronomy, 28 July 2026 (DOI 10.1038/s41550-026-02939-x; arXiv 2607.24911). Tohoku University release. • “White Dwarfs Eat More Planetary Debris Than Thought, But Magnetic Fields Hide It,” Universe Today, 29 July 2026 (Pham et al., arXiv 2607.20747). • “NASA’s Psyche Spacecraft Aces Mars Flyby,” NASA JPL / ScienceDaily, 28 July 2026. • “The Risks of Debris Between the Earth and the Moon for Future Exploration,” Universe Today, 29 July 2026 (Chinese Academy of Sciences DRO study). • Double meteor shower peak: American Meteor Society; NASA; Scientific American; CNN; National Geographic, 28–30 July 2026. 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.

ESO’s VLT/SPHERE has captured the clearest direct image yet of Betelgeuse B, the long-suspected companion to the famous red supergiant — ending a roughly century-long search. Published 28 July 2026 in Astronomy & Astrophysics (Montargès, Boccaletti et al.). The companion is more massive than predicted (≈2–3 solar masses), likely paces Betelgeuse’s ~6-year brightness cycle, and may eventually spiral into the supergiant. • Swift catches a wandering black hole. TDE 2025abcr — the most off-centre tidal disruption event ever seen — reveals a ~1-million-solar-mass “wandering” black hole ~30,000 light-years from its galaxy’s core, ~750 million light-years away. First flagged by the Zwicky Transient Facility (Nov 2025) and pinned down with NASA’s Swift; an AI sifted ~500,000 nightly flashes to find it. Published 27 July 2026 in The Astrophysical Journal Letters (Stein et al.; Carney et al.). • Roman is fuelled for launch. NASA’s Nancy Grace Roman Space Telescope completed fuelling on 25 July (≈290 gallons of hydrazine) and holds its mission-preview briefing today — one month from a 30 August launch, roughly eight months ahead of schedule. Roman will survey ~50× as much sky as Hubble in five years, probe dark energy, and is expected to find 100,000+ exoplanets via microlensing. • Swift’s rescue mission is in trouble. Katalyst’s LINK servicing spacecraft — launched 3 July to boost the decaying Swift observatory — began spinning over the weekend; two of three reaction wheels are non-operable, with some cold-gas thruster degradation. LINK remains powered and in contact; the team is using its electric (xenon) thrusters to arrest the spin before deciding, with NASA, whether to proceed. Developing story — details accurate as of recording. • Skywatch. Full Buck Moon tonight (29 July); Jupiter at solar conjunction; Southern Delta Aquariids favour the Southern Hemisphere but are washed out by the Moon this year; Alpha Capricornid fireballs are the pick for both hemispheres; the Perseids peak on the moonless night of 12–13 August alongside a total solar eclipse (Greenland/Iceland/Spain; partial for parts of Europe and North America). Never view the partial phases without ISO 12312-2 eclipse glasses.
