Embark on an interplanetary journey with SpaceTime Series 27 Episode 59, where we unravel the enigmatic atmosphere of Venus and its waterless environment. Discover the startling new study that suggests Venus lost its water reserves to space, leaving it with a mere fraction of Earth's water despite their similar origins. The episode dives into the complex chemical reactions in Venus's atmosphere that may have turned a once Earth-like planet into a scorching, inhospitable world. Next, we explore the innovative ideas NASA is considering for future lunar logistics, including a magnetic railroad system designed to transport materials across the Moon's surface. This system could revolutionize the way we build and sustain lunar bases, pushing the boundaries of off-world construction and resource utilization. The episode then shifts to the launch of a cutting-edge satellite from the International Space Station. This new eye in the sky aims to provide early warnings of volcanic eruptions by detecting trace gases, a game-changer for disaster preparedness and environmental monitoring. Join us as we delve into these cosmic developments and more, including the implications of AI biases and the latest in tech from Apple.

Join us for SpaceTime Series 27 Episode 69, where we uncover the latest cosmic revelations and scientific advancements. First, we delve into a groundbreaking discovery by the Webb Space Telescope, which has identified the most distant galaxy ever observed. Located a staggering 290 million years after the Big Bang, this galaxy offers unprecedented insights into the universe's infancy and the formation of its earliest stars and galaxies. We explore the methods and implications of this discovery, including the galaxy's surprising brightness and the presence of dust and ionized gas. Next, we discuss the announcement of a massive new collection of exoplanet discoveries. NASA's Transiting Exoplanet Survey Satellite (TESS) has confirmed 120 new exoplanets and identified six new candidates, bringing the total number of known exoplanets to over 6000. These findings offer a rich database for studying planetary properties and environments, particularly those that may harbor life. Finally, we highlight new X-ray observations from NASA's Chandra X-ray Telescope, revealing dramatic changes in two famous supernova remnants: the Crab Nebula and Cassiopeia A. These observations provide stunning visualizations and valuable data on the dynamic processes occurring in these remnants.

Show notes A rose-coloured rock picked up in the Sahara in 2022 turns out to be one of the oldest pieces of Mars ever found. Teghaza 001 formed at least 4.1 billion years ago, and two independent radiometric clocks agree. We explain how it was dated, what it says about early Mars losing its water, and why its source is still a shortlist of 13 craters in the southern highlands. Also: Voyager 1 goes silent for two days and recovers on its own as it nears one light-day from Earth on 18 November; Hubble finally sees the 'Cat's Tail' of Beta Pictoris, the wreckage of a collision between two Pluto-sized worlds; two Halloween ghosts in the Carina Nebula; and quick hits on the 100th US spacewalk from the ISS, Reid Wiseman's move to JPL, Swift and Starship. Skywatch: US clocks go back on 1 November, Saturn in the evening, Venus returns to the morning sky, Mars and Jupiter close in, the Moon passes Pollux, Mars, Jupiter and Regulus, the Southern Taurids, and Carina for southern observers.

Episode summary Betelgeuse is being haunted. New VLA and ALMA radio observations show the red supergiant's atmosphere stretches and relaxes in step with the orbit of its hidden companion, Siwarha — a companion too faint to see in radio, caught by the ripples it leaves behind. Also: lithium-fluoride crystals that rode around the Moon on Artemis I, why comets almost certainly didn't deliver life's ingredients to Earth (but did better on Mars), and Virgin Galactic's new spaceship, Apeiron. Plus Swift's final days, Hubble helping Roman, Starship Flight 15, and where to find Betelgeuse tonight from both hemispheres. Show notes The Ghost in Betelgeuse · Matthews (MIT Haystack), Dupree (CfA), Richards (Manchester) and Dent (ESO/ALMA) imaged Betelgeuse at seven frequencies, 22–485 GHz, with the VLA and ALMA between 2021 and 2026. · The outer atmosphere has recovered from the 2019–20 Great Dimming (~3,500 K at 22 GHz); a temperature minimum of ~2,220 K sits at ~1.2 stellar radii, matching the infrared 'MOLsphere'. · The star's ellipticity tracks the orbital phase of its companion Siwarha: more stretched near greatest elongation (~10% in Oct 2024), rounder near transit and eclipse (2% in Apr 2026). · Caveats: small effect, ~9 epochs, frequency-dependent orientation puzzle, Siwarha's nature contested; preprint posted August 2026. · Next: Siwarha re-emerges on the far side of Betelgeuse in late 2027. Crystals That Went Around the Moon · Bilski et al. (IFJ PAN, DLR), Radiation Measurements: LiF fluorescent nuclear track detectors from the MARE phantoms on Artemis I reconstructed the cosmic-ray energy-deposition spectrum without destroying the detector. · Matched plastic track detectors at intermediate energies; ~30% overestimate for the heaviest ions, attributed to neutron knock-on of lithium nuclei; lithium-7 crystals reduce it. · Near the Moon, dose was higher than in low Earth orbit but less than intuition suggests, and more evenly spread through the body. Comets Probably Didn't Seed Life on Earth · Anslow et al. (Cambridge), Scientific Reports: rapid decline of the bombardment, comet break-up, atmospheric filtering, impact heating and crater-lake dilution make HCN delivery to early Earth 'exceedingly rare'. · Delivery to Mars is about five times more effective (lower impact speeds, thinner atmosphere). · Caveat: modelling, focused on HCN; doesn't exclude delivery in tightly packed exoplanet systems. Virgin Galactic's Apeiron Comes Home · First Delta-class spaceplane named Apeiron ('boundless') on 28 Oct and flown under mothership Eve from Mesa, Arizona to Spaceport America. · Flight tests next; customer flights targeted mid-2027; second ship late 2027; target twice-weekly flights and 500+ missions per vehicle. Quick Hits · Swift ended operations 20 Oct; NASA expects re-entry within weeks. · Hubble lens image DESI J194.5345+03.5358 released to help calibrate Roman's ~160,000 expected strong lenses (image release, no new paper). · Starship Flight 15 targeted for November with a two-stage catch attempt; no official date. Skywatch · Betelgeuse rises ~22:33 Sydney, 21:48 LA, 21:46 NY, 20:39 London (Fri 30 Oct); highest before dawn: 49° Sydney, 63° LA, 57° NY, 46° London. US clocks fall back Sun 1 Nov. · Saturn at dusk; Mercury's last evening appearance favours the south (~11° at sunset from Sydney). · Pre-dawn Mars–Jupiter closing: 6.5° (this weekend), ~4° (5 Nov), ~1.2° (16 Nov). Last quarter Moon 1 Nov 20:28 UTC; Moon past Mars, Jupiter and Regulus 2–3 Nov. · Zodiacal light: evening west from the south, pre-dawn east from the north. Solar viewing only with ISO 12312-2 filters.
