Today's episode — S05E168, Saturday August 15, 2026, our "Weekend Wrap":**Main story: a magnetar confirms 90-year-old vacuum birefringence prediction.** A team led by Rachael Stewart (George Washington University), using NASA's IXPE spacecraft, found the strongest evidence yet that extreme magnetic fields polarize light passing through empty space — confirming a 1936 prediction by Werner Heisenberg and Hans Euler. The team studied magnetar 1E 1547-5408 and found X-rays nearly 3x more polarized than expected, in a direction matching the star's magnetic field. Published August 5 in *Nature*.**The week in review:**- **Starship:** Ship 40 (Flight 13, splashed down July 24) remains adrift in the Indian Ocean after recovery efforts stalled in rough seas; Elon Musk said August 7 that recovery is "not looking good right now." Still unresolved as of this weekend — roughly 18% recovery odds per prediction markets. SpaceX has moved on to Flight 14 prep (Ship 41, targeting ~August 20).- **Eclipse:** The August 12 total solar eclipse swept a 182-mile shadow from the Arctic through Greenland, Iceland (2m18s max totality at Látrabjarg) and northern Spain. Next Spanish total eclipse: August 2, 2027.- **Black hole star:** JWST's "Mirage or Miracle" survey identified MoM-BH*-1, a gas-shrouded black hole glowing from just 660 million years after the Big Bang — a candidate explanation for how supermassive black holes grow so fast.- **Virgin Galactic:** Commercial flights delayed again, from Q4 2026 to February 2027; Q2 earnings (revenue $1.54M, net loss ~$55.9M) sent shares down further, with heavy cash burn guided for Q3/Q4 and a new shelf filing for capital flexibility.**Links & sources:**- [Space.com — Is empty space really empty?

Anna and Avery break down JWST's discovery of MoM-BH*-1, the earliest known "black hole star" — a black hole shrouded in dense gas, glowing from just 660 million years after the Big Bang, that might explain how supermassive black holes grow so fast. Plus: the Perseid meteor shower's spectacular overnight peak, a new satellite built to watch other satellites in geostationary orbit, and veteran NASA astronaut Mike Fincke's retirement after 30 years and four spacecraft.**Full show notes:**Today's episode — S05E167, Friday August 14, 2026:**Main story: JWST finds the earliest known "black hole star."** Astronomers led by Rohan Naidu (University of Hawai'i) and Jorryt Matthee (ISTA) identified MoM-BH*-1 — a young black hole wrapped in a dense gas envelope so thick it radiates almost like a star, appearing over 100,000 times the Sun's radius. Light from the object left it roughly 13 billion years ago, just 660 million years after the Big Bang. The discovery, from the "Mirage or Miracle" JWST survey, may explain how supermassive black holes grow fast enough to match observations of the early universe, and may be linked to the population of mysterious "little red dots" Webb has found since 2024.**The Perseid meteor shower's spectacular peak.** The Perseids peaked overnight on August 12–13, just hours after this week's total solar eclipse, with dark, moonless skies delivering hundreds of visible meteors per hour at the best sites. Debris from comet 109P/Swift-Tuttle remains active through roughly August 24.**Astranis unveils Perceptor.** A new satellite line built to monitor activity in geostationary orbit, using electric propulsion for repeated multi-angle flybys of other spacecraft. Astranis CEO John Gedmark cited past close approaches by Russian and Chinese spacecraft near U.S. satellites as motivation. No launch date announced yet.**Astronaut Mike Fincke retires after 30 years.** Fincke flew four missions across four spacecraft types — Soyuz (twice), Space Shuttle Endeavour, and SpaceX Crew Dragon Endeavour — commanded the ISS twice, and capped his career with Crew-11, a mission cut short in January after a frightening in-orbit medical incident.**Links & sources:** - [EurekAlert — Mirage or miracle?

Anna and Avery break down yesterday's total solar eclipse — a 182-mile-wide shadow that swept from the Arctic through Greenland and Iceland to northern Spain, giving millions of people up to 2 minutes 18 seconds of totality. Plus: astronomers find three supermassive black holes sharing one distant galaxy (two are about to merge), Virgin Galactic pushes commercial spaceflight back to February 2027, and Rocket Lab signs a new launch customer for Neutron even as the rocket's debut slips further.**Full show notes:**Today's episode — S05E166, Thursday August 13, 2026:**Main story: The August 12 total solar eclipse.** The Moon's shadow crossed the Arctic Ocean, eastern Greenland, western Iceland, northern Spain, the Balearic Islands and out into the Mediterranean. Longest totality on land: 2 minutes 18 seconds at Látrabjarg, Iceland. Millions gathered across northern Spain, with the path also crossing A Coruña, Bilbao, Zaragoza, Valencia and Palma (Madrid and Barcelona were just outside the path). Observers reported seeing the solar corona, a prominence, and Jupiter, Mercury and Venus during totality. Spain gets another total eclipse on August 2, 2027.**Three supermassive black holes, one galaxy.** Astronomers led by Hannah Übler (Max Planck Institute for Extraterrestrial Physics) used JWST to confirm three actively feeding supermassive black holes in galaxy J0148-4214, 12.5 billion light-years away — the first such triple system ever confirmed. Two of the three are on course to merge.**Virgin Galactic delays commercial flights to 2027.** The company's upgraded Delta-class spaceplane will now begin commercial service in February 2027, pushed back from Q4 2026, to complete avionics and systems installation.

In this episode • Shadow Day: the only total solar eclipse of 2026 crosses Arctic Russia, Greenland, western Iceland and northern Spain today — the first total eclipse over western mainland Europe since 1999 (Spain’s first since 1905, Iceland’s since 1954). Max totality ~2 min 18 s. Reykjavík ~17:48 UT; northern Spain ~18:27–18:33 UT (Sun very low, ~4–10° up). Live via NASA, timeanddate and the Exploratorium. • Where you are: North America gets an afternoon partial (Nova Scotia ~33%, N. Maine ~28%, Montreal ~18%, Boston ~16%, NYC ~9–10%, Toronto ~8%, DC ~10%; Fairbanks ~37% in the morning) — no totality anywhere on the continent, glasses on throughout. Europe outside the path sees a deep evening partial (London ~91%). Australia/SH: not visible directly — watch the streams (~1:30–6:00 am AEST Thu). • Chasing the shadow: NASA’s WB-57 jet flies the path at ~50,000 ft (~740 km/h), extending totality to nearly 3 minutes with four visible/IR cameras (SCIFI) to probe coronal heating, prominences and the solar wind (PI Amir Caspi, SwRI). The Nationwide Eclipse Ballooning Project (A. Des Jardins, Montana State) launches ~86 balloons from Iceland and Spain to measure atmospheric changes. • A star-building magnetic field: ALMA captures the first direct high-resolution image of a twisted, toroidal magnetic field wrapped around a protostellar jet in NGC 1333 IRAS 4A (~960 ly, Perseus cloud), confirming a decades-old prediction of how young stars launch jets and shed spin — the same physics that scales up to black-hole jets (Ching et al., Nature Communications 2026; NSF NRAO/ALMA). • Why worlds turn hellish: UC Riverside’s Stephen Kane argues planetary rotation is an overlooked driver of climate and habitability — slow spin may help tip a world into a Venus-style runaway greenhouse. Measuring true spin is hard because winds can masquerade as rotation; ESA’s PLATO (launch March 2027) could test the idea across hundreds of Venus-like planets (Astronomical Journal, accepted). • Skywatch — both hemispheres: the Perseids peak overnight 12–13 Aug under a genuinely moonless sky (best midnight–dawn; NH-favoured). Southern Hemisphere: evening Venus (mag −4.4, just past dichotomy), the pre-dawn planet line-up, and Comet 10P/Tempel 2. ISO 12312-2 eye-safety line included.

Astronomy Daily · S05E164 “Eclipse Eve” · Tuesday 11 August 2026. Sources are primary/agency where possible; aggregator dates were checked against originals. In this episode • LEAD — The 12 August total solar eclipse: the only total eclipse of 2026 and the first over mainland Europe since 1999. Totality arcs from Siberia over the North Pole to eastern Greenland, western Iceland, northern Spain and a sliver of Portugal; maximum totality ~2 min 18 s. Partial for much of North America near sunset; not visible from Australia. ESA livestreams from the Javalambre Observatory, Spain. • MIDDLE 1 — A state CASC Long March 7A exploded ~85 seconds after lifting off from Wenchang on 10 August, a total loss (payload reported as the Zhongxing-4B communications satellite). Separately, Landspace’s private Zhuque-3 was on the same-night manifest from Jiuquan for its second propulsive landing-legs recovery attempt — outcome unconfirmed at recording. China’s first orbital-booster landing (net-capture, Long March 10B) already succeeded on 10 July. • MIDDLE 2 — The Perseids peak overnight 12–13 August under a New Moon — the darkest conditions in roughly two decades. Parent comet 109P/Swift-Tuttle. Realistic ~30–50 meteors/hr from dark sites (nominal ~100), with a slim chance of a dust-trail boost; the next confidently forecast outburst is 2028. • MIDDLE 3 — Japan’s H3 launched Michibiki No. 7 (QZS-7) from Tanegashima, bringing the Quasi-Zenith Satellite System up to the strength Japan needs to run it as a standalone service — a regional navigation layer that keeps a satellite near the zenith over Japan/Asia-Pacific, reinforcing GPS and building navigation resilience. The satellite also hosts a US Space Force space-surveillance sensor (SACHI). • CLOSER — Both-hemispheres skywatch: eclipse viewing times (totality window ~16:58–18:34 UT, greatest ~17:46 UT) and the ISO 12312-2 eye-safety rule; Perseid how-to for the North (best 2 a.m.–dawn); and Southern-Hemisphere content — pre-dawn planets, evening Venus, Comet 10P/Tempel 2. Eye safety • A partial eclipse is never safe to view with the naked eye. Use ISO 12312-2 certified eclipse glasses/viewers, or indirect projection (pinhole). Direct viewing is only safe during true totality, and only inside the path (Greenland, Iceland, Spain).

Astronomy Daily · S05E163 · “The Long Way Home” · Monday 10 August 2026. Sources verified against primary / institutional outlets. Starship “lost at sea” (Flight 13) • Flight 13 launched 24 July 2026 from Starbase, South Texas; the upper stage (“Ship,” Ship 40, ~52 m) made the softest Starship water landing yet in the Indian Ocean off Western Australia — and, in a program first, survived intact and afloat. • SpaceX had not planned to recover it. Musk confirmed the salvage attempt on 28 July (“We’re sending a ship out to recover Starship”); recovery ship Go Australis was joined by Norwegian tugs Normand Ranger and Skimmer Tide, with a tow line to the nose. • On 7 August, Musk said recovery is “not looking good right now” in rough seas — but the team had already obtained close-up photos of critical heat-shield and engine regions for future upgrades. A saltwater-soaked Ship was never going to be reflown. • Heat shield: on SpaceX’s first quarterly earnings call (4 August) Musk said he’d “consider the heat-shield problem solved,” long the biggest hurdle to full reuse. • The flight also deployed 20 next-gen Starlink V3 satellites; the Super Heavy booster had engine trouble and was lost in the Gulf of Mexico. Stacked, Starship stands ~124 m. Flight 14 is targeted for late August — its first attempt at operational orbit with production Starlink. • Sources: SpaceX / @elonmusk on X (7 Aug); Space.com (Mike Wall, 7 Aug); CNN (3 Aug). Landspace Zhuque-3, second landing attempt • Landspace (private, Beijing, founded 2015) targets liftoff ~7:45 p.m. EDT Mon 10 Aug (23:45 UTC / ≈9:45 a.m. AEST Tue 11 Aug) from Jiuquan, aiming for a propulsive first-stage recovery on legs (Falcon 9-style), landing downrange in Gansu. • The methalox, stainless-steel Zhuque-3 (~66 m) is broadly a Falcon 9 rival. Its Dec 2025 maiden flight reached orbit but the first stage failed its landing burn and crashed. • Accuracy note: this is China’s fourth orbital-class recovery attempt. A Long March 10B already landed via net-capture on 10 July (China became the 2nd nation to land an orbital booster) — so tonight would make Landspace the first Chinese company to attempt a propulsive/landing-legs recovery, not “China’s first.” • Sources: Space.com (7 Aug); Yahoo/Space (7 Aug); launch trackers (NOTAM-based). Uranus’s “breathing” bow shock • New multifluid-MHD modelling shows Uranus’s bow shock expands and contracts over a single ~17-hour Uranian day — driven by the planet’s own extreme rotation and tilted, offset magnetic field, not by changes in the solar wind. • The model is constrained by Voyager 2’s 1986 flyby — still the only direct measurements ever taken inside the Uranian system (a nice callback to E159’s Voyager 2 “Big Bang” lead). • Implications for future ice-giant missions and for the many ice-giant exoplanets now being found. Cao et al., AGU Advances; surfaced via an Eos research spotlight this week. (Framed as newly-spotlighted rather than newly-published.) • Sources: AGU Advances (Cao et al.); Eos research spotlight; phys.org (7 Aug). Total solar eclipse — 12 August 2026 • The only total solar eclipse of 2026. Unusual over-the-pole path: Arctic Siberia → eastern Greenland → western Iceland → northern Spain (clipping NE Portugal) → the Balearics at sunset. • Greatest eclipse ≈17:46 UTC; max totality 2 min 18 s just off Iceland’s west coast, with the Sun only ~26° high. Iceland’s first total eclipse since 1954 (Reykjavik’s first in 593 years); Spain’s first since 1905. • North America sees a partial across the northern tier (Alaska to North Carolina) and most of Canada — deepest in the far north, a shallow bite (<10%) from the US Northeast, late morning to early afternoon local. NASA livestream from 1:15 p.m. EDT at nasa.gov/live. • Not visible from the Southern Hemisphere. Sources: NASA eclipse pages; national eclipse guides. Skywatch — both hemispheres • Perseids peak the night of 12–13 August...

Astronomy Daily · S05E161 · “The Colour of Empty Space” · Friday 7 August 2026. Hosts: Anna & Avery. astronomydaily.io · @AstroDailyPod ① Vacuum birefringence: reading a magnetar ● NASA’s IXPE, with NICER and the Parkes/Murriyang radio telescope (NSW), measured the polarised X-rays of magnetar 1E 1547.0−5408. ● Result: soft X-ray polarisation ~65% at 2 keV, rising to nearly 80% at some rotation phases — the strongest signal yet of vacuum birefringence, a QED effect predicted by Heisenberg in 1936. ● The team calls it the “most definitive signal to date,” not a confirmed detection; an April 2026 analysis disputes it under different geometry. Co-leads: Rachael Stewart; Hoa Dinh Thi (Rice); with Marcus Lower (Swinburne). ● Source: Stewart et al., Nature, 5 Aug 2026 (DOI 10.1038/s41586-026-10859-z); NASA IXPE release. ② Gateway HALO hardware → Lunar Infrastructure Demos ● NASA and Northrop Grumman are repurposing the HALO module’s power, data and avionics into three surface missions — LID-1, LID-2, LID-3. ● Goal: “survive-the-night” power and thermal tech for the lunar South Pole, where night lasts ~14 Earth days and temperatures plunge below −200 °C. ● Part of a wider Moon-base update in which four commercial landers reached final qualification testing at once. ● Source: NASA & Northrop Grumman releases, 4 Aug 2026; Spaceflight Now. ③ New Glenn: the cause is a valve ● Blue Origin traced the 28 May New Glenn booster explosion (during a pad hot-fire at Cape Canaveral) to the main oxygen valve on one of the seven BE-4 engines. ● Fix: small, retrofittable valve modifications; return to flight still targeted by year’s end. The BE-4 also powers ULA’s Vulcan. ● Source: Blue Origin CEO Dave Limp, 5 Aug 2026; SpaceNews. ④ LINK’s de-spin: the fight to save Swift ● Katalyst Space’s LINK robot — tasked with boosting NASA’s ageing Swift observatory before re-entry — hit a multi-axis tumble when two of three reaction wheels failed. ● Using gimballed electric-propulsion thrusters, the team cut the spin from ~9°/s to ~1.47°/s on under 100 g of propellant. A flight-software update is next; rendezvous slips to ~end of August. ● Source: NASA Swift blog, 6 Aug 2026; Katalyst mission updates. ⑤ Skywatch: eclipse + Perseids ● 12 Aug total solar eclipse — totality across Greenland, Iceland, northern Spain; afternoon partial for eastern Canada and the NE United States (>10% only NE of the NYC–Rochester line; ~50% in Atlantic Canada). NASA live from 1:15 pm EDT. ● Perseid peak the night of 12–13 Aug under a New Moon — up to ~100/hr from dark rural sites. ● Southern Hemisphere: eclipse not visible; Perseids barely clear the horizon. Sydney: pre-dawn planet line-up + Venus + winter Milky Way. ● EYE SAFETY: use only ISO 12312-2 eclipse glasses for every partial phase; never combine them with a camera, telescope or binoculars.

Astronomy Daily · S05E160 · 6 August 2026. In this episode: a Falcon 9 upper stage confirmed to have struck the Moon; a live ISS spacewalk; supernova SN 2026gzf caught at first light; SpaceX Crew-13 previewed; and a both-hemispheres guide to the 12 August eclipse and Perseids. FALCON 9 LUNAR IMPACT (LEAD) ● Spent upper stage 2025-010D struck near Einstein Crater (~19.4°N, 93.3°W) at ~06:35 UTC, 5 Aug 2026 — matching Bill Gray / Project Pluto predictions. ● ESO’s Very Large Telescope (Paranal) detected sodium and lithium in the impact plume for ~5–10 minutes — sodium from lunar soil, lithium likely from the rocket. ● NASA’s Lunar Reconnaissance Orbiter holds a pre-impact baseline and will image the fresh crater, giving a rare before-and-after dataset to validate hollow-body impact models for future landers. ● Origin: Falcon 9 launched 15 Jan 2025 with Firefly Blue Ghost 1 and ispace Resilience; the stage was left adrift and returned unplanned via solar activity and gravity. ● Sources: NASA; ESO / VLT; CNN; Project Pluto (projectpluto.com); Fernando et al., arXiv:2607.14625. ISS SPACEWALK — U.S. EVA 96 ● NASA’s Jessica Meir (Expedition 75 commander) and Anil Menon; ~6.5 h EVA beginning ~08:35 EDT, 6 Aug; live on NASA+. ● Task: reconfigure the 3B power channel to accept a seventh roll-out solar array later in 2026 — part of station upkeep ahead of the planned 2030 deorbit. ● Menon’s first spacewalk; two further EVAs scheduled 13 and 25 Aug. ● Sources: NASA / NASA+ ; NASA ISS blog. SUPERNOVA SN 2026GZF ● X-ray “shock breakout” (EP260321a) detected by China’s Einstein Probe on 21 Mar 2026 from a galaxy ~500 million light-years away; follow-up revealed a broad-lined Type Ic supernova. ● Unusually, no gamma-ray burst and no lasting relativistic jet — and the faintest shock breakout yet linked to this class; a possible missing link between ordinary and GRB-producing supernovae. ● Follow-up used NSF NOIRLab facilities including DECam and the Vera C. Rubin Observatory. Two teams: O’Connor et al. (CMU) and Rastinejad et al. (UMD), in ApJL. ● Sources: NSF NOIRLab; Carnegie Mellon University; The Astrophysical Journal Letters. SPACEX CREW-13 ● Targeting NET 12 Sep 2026 aboard Crew Dragon Grace from SLC-40, Cape Canaveral. ● Crew: Jessica Watkins (NASA, cmdr — first NASA astronaut to fly Dragon twice), Luke Delaney (NASA, pilot), Joshua Kutryk (CSA), Sergey Teteryatnikov (Roscosmos). 180-day stay; moved up from November. ● Sources: NASA; SpaceX; Houston Public Media. SKYWATCH — 12 AUGUST & BEYOND ● Total solar eclipse 12 Aug: totality across E Greenland, W Iceland, N Spain and NE Portugal (max 2m18s). Partial across northern US (Alaska–N Carolina), most of Canada, much of Europe and NW Africa. NASA livestream from 1:15 pm EDT. ● US partial highlights: Presque Isle ME ~29% (contiguous-US max); NYC ~9% from ~1:07 pm EDT; Boston ~16%; Toronto ~8%; Montreal ~18%; St John’s ~53%. ● Perseids peak 12–13 Aug under a new Moon (northern-favoured, up to ~100/hr from dark northern sites). ● Southern Hemisphere: pre-dawn planet parade (Saturn best, near opposition; Mars, Mercury, Uranus, Neptune), brilliant Venus in the evening west, and the winter Milky Way high overhead. ● Look-ahead: deep partial lunar eclipse 28 Aug (96% umbral), favouring the Americas. ● SAFETY: use only ISO 12312-2 certified eclipse glasses / solar filters during any partial phase. ● Sources: NASA; ESA; Sky & Telescope; BBC Sky at Night; EarthSky; timeanddate.com; The Planetary Society.Become a supporter of this podcast: https://www.spreaker.com/podcast/astronomy-daily-latest-space-news--5648921/support.<br...

Astronomy Daily S05E159 — Wednesday, 5 August 2026. In this episode: a power-saving “Big Bang” keeps Voyager 2 doing science, direct-to-phone satellites reach orbit, Curiosity finds a vast honeycomb field on its 14th Martian anniversary, and NASA’s Aspera prepares to hunt the universe’s missing gas. ① Voyager 2’s “Big Bang” power save • JPL engineers freed up power by simultaneously switching off certain devices and substituting lower-power alternatives, while keeping the spacecraft warm enough to operate. • The Voyagers run on radioisotope thermoelectric generators (RTGs) and lose ~4 watts per year as their plutonium decays; after nearly 50 years, power margins are razor-thin. • The move keeps three instruments — magnetometer, plasma wave subsystem and cosmic ray subsystem — running at least a year longer; the same swap is planned for Voyager 1. • Voyager 2 crossed the heliopause in Nov 2018 and is now >13 billion miles (21 billion km) from Earth; its southerly path means it is commanded via the Canberra Deep Space Network dish.

Source: AST SpaceMobile / Space.com, Aug 2026 · confirm deployment before publish ③ Curiosity’s “sea of polygons” + 14 years • Curiosity found its largest-ever field of honeycomb-like polygonal fractures (each ~4–8 cm across) in a valley nicknamed “Valle Grande” on Mount Sharp. • The 360° panorama was captured on 19–20 June from 340 images; the polygons wrap around a ~6 m butte nicknamed “Miraflores.” • Such patterns point to ancient water — drying mud, wet–dry cycles, or compaction — consistent with lakes and streams once present on Mount Sharp’s foothills. • Today, 5 August, is Curiosity’s 14th landing anniversary (landed 5 Aug 2012). Source: NASA/JPL, announced ~29 Jul 2026 · jpl.nasa.gov ④ NASA’s Aspera (mission preview) • Aspera is a shoebox-sized NASA Pioneers smallsat launching NET 15 Aug on a Rocket Lab Electron from Mahia, New Zealand. • It is the first NASA astrophysics mission to map the circumgalactic medium — hot gas around galaxies — in ultraviolet light, tracing the “missing baryons.” • Led by Carlos Vargas at the University of Arizona, one of the youngest principal investigators in NASA history.
