Three of a Kind
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.

The Reach of a Giant | A Black Hole Story
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).

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.

Betelgeuse Is Not Alone!
Astronomy Daily · S05E153 · Wednesday 29 July 2026. Four stories from the frontier of space and astronomy, plus a both-hemispheres look at the sky — and news of our brand-new website. In this episode • Betelgeuse is not alone. 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. Sources • ESO release eso2611 & Astronomy & Astrophysics, Montargès, Boccaletti et al., “VLT/SPHERE imaging of the candidate companion of Betelgeuse” (28 Jul 2026). • NASA Swift / The Astrophysical Journal Letters — TDE 2025abcr wandering-black-hole discovery (27 Jul 2026); UNC-Chapel Hill release. • NASA — Nancy Grace Roman Space Telescope fuelling & launch-preview updates (25–29 Jul 2026). • NASA Swift blog — “Commissioning Update for Spacecraft to Boost NASA’s Swift” (28 Jul 2026); Katalyst Space Technologies. • EarthSky, NASA, American Meteor Society, timeanddate — meteor showers, Buck Moon, Jupiter conjunction, 12 Aug eclipse.

Reading Io’s Hidden Heat: Juno’s First Subsurface Reading | Today’s Space News
Astronomy Daily S05E152 — “Reading the Heat” · Tuesday 28 July 2026. Hosts Anna & Avery. NASA’s Juno spacecraft has taken the first-ever temperature reading beneath the surface of Io, Jupiter’s volcanic moon — and the technique behind it could reshape how we study icy ocean moons and even volcanoes on Earth. We also look at why JWST’s “Little Red Dots” might be globular clusters being born, the first SETI search built from archived ALMA data (and its six-million-star surprise), and a live burst of space weather feeding into a meteor-filled — if Moon-washed — skywatch. In this episode ● Juno reads Io’s subsurface temperature for the first time — >20°C rise within a few metres, heat flow up to ~30× Earth’s average, and a remarkably smooth, low-density surface. ● Why the method matters: a multi-depth microwave thermometer that works from orbit — promising for Europa, Enceladus, and terrestrial volcanology. ● JWST’s “Little Red Dots” may be globular clusters in formation, powered by a short-lived supermassive star — linking two long-standing mysteries. ● The first SETI survey of archived ALMA data opens the millimetre band — and reveals “stellar bycatch” of 6.1 million background stars. ● Live space weather: an M3.2 flare from region AR4494 and a glancing CME, with G1–G2 storms and possible aurorae, north and south. ● Skywatch: meteor week under the full Buck Moon (29 July), the Alpha Capricornid fireball tip, evening Venus, pre-dawn Saturn/Mars/Mercury — and Jupiter vanishing behind the Sun. Sources ● NASA/JPL — “NASA’s Juno Takes Temperature of Jupiter’s Fiery Moon Io” (22 July 2026); Brown et al., J. Geophys. Res.: Planets, DOI 10.1029/2025JE009622. ● Chisholm et al., “Little Red Dots as Globular Clusters in Formation,” Astrophysical Journal Letters (press cycle 20 July 2026; UT Austin / McDonald Observatory). ● L. Mason (University of Manchester), first ALMA-archive SETI survey, RAS National Astronomy Meeting 2026. ● Space-weather status: EarthSky Sun news / NOAA SWPC (M3.2 flare AR4494, 26 July; 24 July CME; G1–G2 outlook, 27–28 July). ● Skywatch data: EarthSky, Star Walk, American Meteor Society, NASA — Southern Delta Aquariids (peak ~30 July), Alpha Capricornids (30–31 July), full Buck Moon 29 July, Jupiter solar conjunction 29 July.

Pluto's Big Night & a Sharper Look at M87's Black Hole | Today's Space News
Astronomy Daily · S05E151 · “The Faint Little World Has Its Day” · Monday 27 July 2026 · Hosts Anna & Avery. Pluto has its brightest night of the year — so we go deep on the world nobody can agree how to label. Then a crew comes home after 241 days, the galaxy’s most common planet turns out to maybe hide oceans of molten rock, and the first black hole ever photographed gets a sharper, two-colour read. In this episode LEAD — PLUTO AT OPPOSITION • Tonight Pluto sits opposite the Sun in Capricornus, near its closest point to Earth (~34.5 AU) and at its brightest for the year — yet still only magnitude ~15. • The full arc: Percival Lowell’s “Planet X,” Clyde Tombaugh’s 1930 discovery by blink comparator, and the name suggested by 11-year-old Venetia Burney. • The 2006 IAU reclassification to “dwarf planet” (the “clearing the neighbourhood” rule) — and the still-live debate between dynamical and geophysical definitions of a planet. • What New Horizons found in 2015: the nitrogen-ice plain of Sputnik Planitia, the famous “heart,” water-ice mountains, a hazy atmosphere, and a possible subsurface ocean. STORY 2 — HOME AFTER 241 DAYS • Soyuz MS-28 lands in Kazakhstan with NASA’s Chris Williams and cosmonauts Kud-Sverchkov and Mikaev; ~3,856 orbits, 102M+ miles; Expedition 74→75 handover to Jessica Meir. STORY 3 — SUB-NEPTUNES • New ASU modelling: deep clouds of vaporised rock and salt can act as a thermal blanket, potentially sustaining a hidden magma ocean and reshaping how we read JWST spectra. STORY 4 — M87 IN TWO COLOURS • A Shanghai Astronomical Observatory-led team builds the first spatially-resolved dual-frequency spectral map of M87* (1.3 mm + 3.5 mm, EHT + GMVA), linking the famous ring to the real physics of plasma at the event horizon. SKYWATCH — BOTH HEMISPHERES • South: Southern Delta Aquariids peaking (ZHR ~25) + Comet 10P/Tempel improving into August. North: Mu Cephei, Herschel’s Garnet Star, high in Cepheus. Both: Pluto at opposition, Saturn after midnight in Pisces. Caveat: a ~95% Moon washes out faint targets this week. Sources • NASA — “Astronaut Chris Williams, Crewmates Return from Space Station.” • ASU News / The Astrophysical Journal Letters — Mukherjee et al., clouds and the interiors of sub-Neptunes. • The Astrophysical Journal Letters — Zhao et al., “Spatially Resolved Spectral Properties of M87* on Event Horizon Scales” (DOI 10.3847/2041-8213/ae84ca). • Explore Scientific / Star Walk / astronomy.com — July 2026 observing notes (Pluto opposition, Southern Delta Aquariids, Comet 10P/Tempel, Mu Cephei).Become a supporter of this podcast: https://www.spreaker.com/podcast/astronomy-daily-the-latest-space-news--5648921/support.Sponsor Details:Ensure your online privacy by using NordVPN.

The Moon That Isn't | Today's Space News
Astronomers have confirmed the first moon-like object beyond our solar system — and immediately discovered our vocabulary cannot handle it. A Jupiter-mass world orbits a brown dwarf, which orbits a red dwarf, seventy light-years away. Is it a moon? A planet? Something we have not named yet? Also on today’s show: the Milky Way’s most powerful particle accelerator is confirmed in the direction of Altair, out-punching the Large Hadron Collider by a factor of a hundred. Chandra catches a black hole starving a galaxy it does not even live in. China flies the world’s largest solid rocket from the open ocean for the first time. Starship Flight 13 gets another window.

Far Side | Today's Space News
Astronomy Daily S05E148 — "Far Side" Thursday 23 July 2026 Starship gets a second shot at Flight 13 — with a schedule caveat worth knowing about. The first far-side lunar samples reveal that Earth has been quietly shielding the side of the Moon that faces us. Astronomers debate whether the lunar far side should be closed to industry. The Milky Way's only helium nova finally steps out from behind twenty-five years of dust. And the case that our entire galaxy once turned over. Plus a skywatch closer with a straightforward piece of advice about the Delta Aquariids: do not wait for the peak.In this episode Starship Flight 13 ● Window opens 6:45pm EDT / 2245 GMT Thursday 23 July — 8:45am AEST and 10:45am NZST Friday 24 July. ● Schedule is not locked: Starbase road and beach closure notices point to further Pad 2 testing. ● The 16 July attempt aborted at T-0 when four of 33 Raptors missed start parameters; the limit is three. ● Two Raptors were removed and replaced before this attempt. ● First-ever Starship deployment of V3 Starlink satellites — 20 of them. ● Super Heavy splashes down in the Gulf at ~7 minutes; Ship targets the Indian Ocean off Western Australia at ~65 minutes. No catch attempts. Chang'e-6 and the solar wind ● Published in Nature Geoscience by a team at the Chinese Academy of Sciences' Institute of Geology and Geophysics. ● Based on 1,935 grams of regolith returned from the South Pole–Aitken basin on the lunar far side. ● First direct laboratory comparison of solar wind implantation between the near and far sides. ● Far-side soil records faster, deeper-penetrating particles; the neon isotope ratio sits below every near-side sample measured. ● About a quarter of the solar wind exposure at the Chang'e-5 near-side site involved wind decelerated by Earth's magnetosphere. The far-side site shows none. ● Opens the possibility of using lunar noble gases as a fossil record of Earth's magnetic field over deep time. The far side debate — NAM 2026 ● Held Tuesday 21 July at the RAS National Astronomy Meeting, University of Birmingham. Convened by Prof Martin Ward. ● For the motion: Prof Joe Silk (Johns Hopkins) and Dr Jonathan McDowell (Durham Space Research Centre). ● Against: Dr Nikita Chiu (Durham) and Dr Manuel Salvoldi (aerospace engineer and educator). ● For: the far side is the only radio-quiet site near Earth — critical for detecting the cosmic dark ages, and an exceptional platform for gravitational wave detection. ● Against: commercial investment is what makes lunar exploration sustainable, and governance can let science and industry coexist. ● Audience support for the motion rose from 68% to 76% across the debate. V445 Puppis ● Presented at NAM 2026 by John Mills, University of Warwick. ● The only confirmed helium nova in the Milky Way. Erupted in late 2000, then vanished behind its own dust for over twenty years. ● Now confirmed as a white dwarf accreting from a rare stripped helium star — only a few thousand such stars are thought to exist in the entire galaxy. ● Orbital period of 3.7 days, roughly double previous estimates. Mass transfer has resumed. ● Unexplained high-speed "bullets" of possibly oxygen-rich gas travelling up to 20 million mph (~9,000 km/s) — never seen in any other nova. ● Data from ESO's Very Large Telescope, Hubble, the Southern African Large Telescope and TESS. ● Helium novae may be one pathway to Type Ia supernovae, the standard candles used to measure cosmic expansion. The Milky Way disc flip ● Presented at NAM 2026 by Kirill Batrakov, Durham University. ● Based on 25 Milky Way-like galaxies in the Auriga simulation suite, followed across roughly 11 billion years. ● Galaxies with the most slowly rotating stellar haloes shared a major head-on merger and a disc reorientation greater than 90 degrees. ● Our stellar halo rotates at only 10–20 km/s; the disc moves at around 220 km/s. ● The Gaia-Sausage-Enceladus collision roughly 10 billion years ago is the candidate trigger. ● Batrakov describes a disc flip as likely rather than confirmed, and is looking for independent signatures. ● Separate 2026 work led by Ling Zhu, using 600,000+ giant stars from Gaia and LAMOST, found the outer dark matter halo oriented almost vertically to the stellar disc — consistent with the disc having tilted. Skywatch ● Southern Delta Aquariids are active now, running into late August, with maximum around 30 July. ● Full Moon on 29 July means peak night is close to 98% illuminated — the worst conditions of the run. ● Best window: the pre-dawn mornings from now until roughly 27 July, after moonset. ● Radiant near Skat in Aquarius.
