Spacecraft Drama, Galactic Neighborhoods, and the Push for a Circular Space Economy
- Emergency Return of Shenzhou 20: China's Shenzhou 20 spacecraft is making an uncrewed emergency return to Earth after sustaining damage from a micrometeoroid, which caused a crack in its window. The crew safely returned on a different vessel, marking a significant first for China's space program.
- Galactic Neighborhoods Matter: The Deep Extragalactic Visible Legacy Survey (DEVELS) reveals that a galaxy's local environment significantly influences its evolution. Galaxies in crowded clusters exhibit slower star formation rates compared to isolated ones, providing crucial insights into cosmic evolution.
- Launch Week Extravaganza: This week sees 10 scheduled orbital launches, including five Starlink missions by SpaceX, South Korea's COMSAT 7 satellite launch by Arianespace, and Japan's H3 rocket carrying a critical GPS satellite, highlighting the rapid advancements in the global space industry.
- Ancient Mars Rivers: A new study identifies 16 massive ancient river drainage systems on Mars, suggesting a much wetter past. These findings offer promising locations for searching for signs of past Martian life, utilizing high-resolution data from Mars orbiters.
- Solar Activity Alert: The sun has unleashed a powerful X 1.9 class solar flare, causing radio blackouts and raising concerns about future solar activity. Forecasters are closely monitoring a larger sunspot region that could impact Earth with potential geomagnetic disturbances.
- Sustainable Space Practices: Experts advocate for a circular space economy to combat space debris, emphasizing the importance of designing durable, repairable satellites and creating multi-purpose space stations to ensure sustainable operations in orbit for future generations.

Stellar Breakthroughs: The Discovery of Deuterated Methanol and the First Green Star
Show notes Episode 206 opens with the first results from ALMA's COMPASS survey: the first detection anywhere in interstellar space of fully deuterated methanol, and methanol masers turning up around more than half of a sample of young Sun-like stars. Then the first star that would look green, Magellanic Cloud pulsars recovered from decades-old Parkes data, a supernova caught days old when the universe was 1.2 billion years old, quick hits on Hera, CRS-35 and MMX, and a both-hemispheres skywatch built around the Orionids. Heavy methanol around a newborn star ALMA's COMPASS programme (11 protostars, 100+ hours, seven A&A papers) reports the first interstellar CD3OD around IRAS 4A2 in Perseus (Belloche, MPIfR) and methanol masers in more than half of its low-mass protostars (Jeong, SNU). Deuterium fraction as a formation clock; current models can't reproduce the pattern. The first green star Warwick's Hollands et al. (RASTI) compute white dwarf colours from spectra: WD J1330+6435 comes out chartreuse thanks to accreted sodium; WD J1011+2845 may be the reddest star known. Of 151 white dwarfs within 20 pc, about 1 in 30 is oddly coloured, and the median is white. Pulsars hiding in the Parkes archive Reprocessing Murriyang's Magellanic Cloud surveys finds six pulsars, five in the LMC including a 3.8 s spinner (Sengar et al., preprint); a separate search finds PSR J0103−72, the slowest radio pulsar in the SMC (Wang & Sengar, preprint). A supernova caught days old JWST's NEXUS survey caught AT 2026abck at z = 5.017 roughly 4–10 rest-frame days after explosion — the first robust z ≳ 5 transient in an unlensed field (preprint; no spectrum yet). Quick hits Hera's BRM-1 braking burn (result pending at recording), CRS-35 docks with the last iROSAs, and MMX launches Tuesday morning Japan time. Skywatch First quarter 18 Oct, Orionids peak 21–22 Oct with the Moon down before dawn everywhere, evening Mercury for the south, Venus heading into conjunction, Saturn after dark, Mars and Jupiter closing before dawn.

Martian Mystery: Unveiling the Secrets of Arsia Mons' Elusive Clouds
Show notes A cloud on Mars that forms only if textbook-theoretical physics really happens; Webb maps a hot Jupiter's edge angle by angle; multi-planet systems turn out to come in two families tied to their stars; and the Sagittarius dwarf galaxy's original disc is rebuilt from its own debris. Plus Hera's first braking burn, the station's final solar arrays, NASA ADS hands over to SciX, and a both-hemispheres skywatch. The Cloud That Shouldn't Exist Every morning in Mars's southern spring and summer, the Arsia Mons Elongated Cloud stretches up to 1,800 km from the 20 km volcano and vanishes within the day. A team led by Jorge Hernández-Bernal (LMD/CNRS/Sorbonne Université) could only reproduce it by adding homogeneous nucleation, in which vapour freezes with no dust seed, at supersaturation more than 100,000 times everyday Earth levels. A model result: sufficient, not yet observed directly. Nature Geoscience, 7 October 2026. A Map Around a Hot Jupiter's Edge Using JWST's NIRISS, NIRSpec and MIRI and the transmission strings method, Lili Alderson, Hannah Wakeford and colleagues mapped WASP-17 b's limb in 20° steps: ~860 K at the morning edge, ~1,520 K at the evening edge, the largest limb contrast yet. Data from March 2023. Nature Astronomy, 14 October 2026. Planetary Systems Come in Two Families Diego Turrini (INAF), Camilla Danielski and colleagues find 298 well-measured multi-planet systems split into a calm, compact low-mass family and a heavyweight family around metal-rich stars with about ten times more dynamical excitation. Nature Astronomy, 13 October 2026. Rewinding a Shredded Galaxy Zixi Guo, Xiang-Xiang Xue (NAOC) and colleagues reproduce a vertical metallicity gradient across the Sagittarius streams only if the dwarf began as a disc with an inverted-V metallicity profile, seen in 3 of 217 MaNGA dwarfs. Nature Astronomy, 13 October 2026. Quick hit Hera's 93-minute braking burn (BRM-1); CRS-35 and the ISS's final roll-out solar arrays; NASA ADS closes in November and becomes SciX. Skywatch Mercury and Venus in the southern evening sky; Venus inferior conjunction 24 Oct; crescent Moon in Ophiuchus; Sagittarius and WASP-17 high from Australia; Saturn all night; Mars and Jupiter closing pre-dawn toward 1.2° on 16 Nov; Orionids peak 21–22 Oct.

Cosmic Revelations: Artemis 2's Historic Observations and the Case of Hypernovae
Show notes Six months after Artemis II swung around the far side of the Moon, NASA has published what the crew saw, said and sketched — including five faint impact flashes spotted during a 54-minute eclipse. Plus: two UCL papers that take apart the chemical evidence for hypernovae, Juno finds Jupiter's magnetodisk crumpled into ripples, and IISc simulations suggest magnetised white dwarfs could grow well past the Chandrasekhar limit. Skywatch: the crescent Moon meets Antares, Mercury and Venus favour the south, Mars leaves the Beehive, and Vesta at opposition.
