   Space Nuts: The M87 Black Hole, a Vanishing Exoplanet and Dragonfly’s Journey to Titan
   

   In this episode of Space Nuts , Andrew Dunkley and Professor Fred Watson revisit the Event Horizon Telescope’s landmark image of the black hole in galaxy M87 — and explain how a CSIRO team has now independently confirmed it using artificial intelligence. They then investigate an exoplanet that stopped transiting its star, apparently because the gravity of another planet has tilted its orbit out of view. Finally, Andrew and Fred Watson look ahead to NASA’s Dragonfly mission to Titan, where a flying rotorcraft will explore a moon with methane and ethane lakes. You can even send your name along for the ride. Join Andrew and Fred Watson for black holes, shifting planetary orbits and an extraordinary mission to Saturn’s largest moon.
   

   Key topics
   

   - How a CSIRO team used AI to independently validate the M87 black hole image.
   

   - Why independent confirmation is an essential part of the scientific process.
   

   - How gravitational interactions may have tilted exoplanet TOI 2535b’s orbit, making its transits disappear.
   

   - Whether the planet may return to view, and if its unseen neighbour could transit its star.
   

   - NASA’s Dragonfly mission, its planned exploration of Titan and how to send your name.
   

   - Titan’s thick atmosphere, icy surface and lakes of liquid methane and ethane.
   

   - How AI is helping scientists make new discoveries.

   A hot Jupiter called TOI-2535 b has become the first planet around a single star seen to stop transiting, tipped out of line by an unseen neighbour. Plus: why Uranus and Neptune have scrambled magnetic fields, MeerKAT measuring how cosmic hydrogen clusters, Euclid's first big data release, ESCAPADE heading for Mars, Starship Flight 15's double-catch attempt, the 2026 ozone hole, and a both-hemispheres sky with Mars and Jupiter 1.2 degrees apart. The planet that stopped transiting. TOI-2535 b, an 8.24-day hot Jupiter ~1,000 light-years away, ran up to ~6 hours early or late and its transits shortened and faded over seven years of TESS data until they vanished in 2026. A hidden companion of at least Saturn mass, likely in resonance on a tilted orbit, is making both orbits precess. Transits should return in 30–50 years. Yee, Petigura et al., The Astrophysical Journal Letters, 9 Nov 2026. Ice giants' scrambled magnetic fields. Dynamo models with electrical conductivity rising with depth reproduce Uranus- and Neptune-like fields, and suggest their tilt could shift by tens of degrees within decades. Aurora observations could test for change since Voyager 2. Yan et al., Communications Physics. MeerKLASS hears the cosmic web. Running MeerKAT's 64 dishes as independent telescopes, the MeerKLASS collaboration detected the 21-cm hydrogen power spectrum on cosmological scales at z = 0.42 over ~236 square degrees, signal-to-noise 6.2. MNRAS. Euclid DR1-Foundation. ~1,900 square degrees (about 1,400 in the southern sky), ~1.8 PB of images, catalogues and spectra. Weak-lensing and clustering products follow in mid-2027. Quick hits.

   Space Nuts: Vanishing Stars, White Holes, Earth’s Mass and Neutrinos
   

   In this listener Q&A episode of Space Nuts , Andrew Dunkley and Professor Fred Watson tackle four cosmic questions that stretch from distant stars to the nature of space-time. They explain why a star billions of light-years away would still appear in our sky long after it had gone out, and why looking across the universe means looking back through time. Next, they consider whether white holes are the opposite of black holes, then investigate whether dark matter could affect our measurements of Earth’s mass and gravity. Finally, they explore how neutrinos interact with gravity, whether black holes can capture them, and why space-time itself is not something a black hole can consume. Join Andrew and Fred Watson Watson for big ideas, listener curiosity and the occasional detour into the value of the Earth in dollars.
   

   Key topics
   

   - How light-travel time means we see distant stars as they were in the past.
   

   - White holes as theoretical solutions to relativity, and how they differ from black holes.
   

   - Whether dark matter contributes to Earth’s measured gravity and mass.
   

   - The mass of the Earth and how astronomers determine it.
   

   - Neutrinos, gravity, black holes and whether space-time can be consumed.

    Light from newborn stars may have blown the fog out of the early universe. A new study by Shyam Menon (Flatiron Institute, ANU PhD) and Aaron Smith (UT Dallas) finds that Lyman-alpha radiation — ultraviolet light that bounces from hydrogen atom to hydrogen atom — can clear diffuse gas and dust out of young galaxies while leaving their dense star clusters free to keep forming stars, helping explain why JWST sees so many bright galaxies so early. Also: LOFAR's sharpest and deepest low-frequency radio image yet (almost 63,000 sources, 200 hours of observing); Blue Origin's new GS3 third stage and Northstar engine; and Sandia simulations showing that an asteroid's shape and orientation can change a nuclear stand-off deflection by up to five times. Quick hits: the space station's final roll-out solar array is installed, sunspot region AR4566 fires an M3 flare as October's sunspot number falls, and Earth picks up a tiny temporary mini-moon, 2026 QQ8. Skywatch for both hemispheres: ESCAPADE's powered flybys over southern Australia, the Moon with Venus and Spica, New Moon on the 9th, globular cluster M30 for southern observers, and Mars closing on Jupiter before dawn.

    Space Nuts: A New Dwarf Planet, 3I/ATLAS, and Neptune’s Hidden Trojans

    In this episode of Space Nuts , Andrew Dunkley and Professor Fred Watson explore three discoveries from across the Solar System and beyond. They begin with the Vera C. Rubin Observatory’s discovery of a distant, potentially large dwarf planet, and discuss what its unusual orbit could tell us about the hunt for the elusive Planet Nine. Next, they examine new James Webb Space Telescope observations of interstellar comet 3I/ATLAS, whose unusual chemistry may preserve clues to its origins in a very cold environment billions of years ago. Finally, the hosts turn to Neptune’s long-sought Trojan asteroids, discovered in data from the Rubin Observatory by a team in Belfast. Join Andrew and Fred Watson for distant worlds, ancient cosmic ice and asteroids hiding in the dark.

    Key topics

    - The Vera C. Rubin Observatory’s discovery of dwarf planet candidate 2026 ED138.

    - What makes an object a dwarf planet, and how its orbit could inform the Planet Nine debate.

    - 3I/ATLAS’s unusual isotope ratios, methane and possible origins in an ancient, cold environment.

    - The discovery of Neptune’s Trojan asteroids and why they have been so difficult to observe.

    ESCAPADE's double slingshot over Australia NASA's twin ESCAPADE spacecraft, Blue and Gold, will each fly a powered Earth flyby on their way to Mars: the first around 5 a.m. EST on Saturday 7 November, the second around 6 a.m. EST on Monday 9 November. Each fires its engine for about nine minutes at closest approach, a manoeuvre NASA says no Mars-bound spacecraft has flown successfully before. The burns happen over southern Australia, starting 8:51 p.m. AEDT on the 7th and 9:51 p.m. AEDT on the 9th, and the spacecraft may be visible there through telescopes. Western US observers get their best chance between midnight and 2 a.m. PST. Arrival at Mars: 7 and 9 September 2027. Where did the oxygen go? Hubble's GLOW project (McQuinn et al., The Astrophysical Journal, published 2 November; preprint since August) measured oxygen in 37 nearby dwarf galaxies and found they keep only 4–25% (about 11% on average) of the oxygen their stars made, nearly all of it in gas. Simulations predict several times more. Supernova-driven winds are the likely culprit; where the oxygen ended up is still unknown. Gas data included CSIRO's Australia Telescope Compact Array. CHAPEA 2: a year on a pretend Mars NASA's second CHAPEA crew, Ross Elder, Ellen Ellis, Matthew Montgomery and James Spicer, left the 3D-printed Mars Dune Alpha habitat at Johnson Space Center on 31 October after 378 days, including communication delays of up to 22 minutes. An integrated HERA-plus-CHAPEA study is planned for 2027. Can a black hole split in two? A theory paper in Physical Review D (Cacciapaglia, Del Piano, Sannino & Vellucci, 22 October; preprint June) finds a split is thermodynamically allowed only, possibly, for black holes spinning near the maximum rate. The splitting process itself remains unknown, and no split has been observed. Quick hits Swift's final re-entry (see episode for status at recording); Starship Flight 15 targeted 12 November on an FAA planning slide, no SpaceX date yet; BepiColombo Mercury orbit capture 21 November; Voyager 1 one light-day from Earth around 18 November. Skywatch ESCAPADE telescope challenge over Australia (Sat 8:51 p.m. and Mon 9:51 p.m. AEDT); New Moon 9 Nov; Taurid fireballs; Mars and Jupiter closing to about 1.2° on 16 Nov (UT); thin crescent Moon under 1° from Venus around 10:45 UT on 7 Nov, best from eastern North America; Venus about 1.2° from Spica on the mornings of 9–10 Nov; Mercury at greatest western elongation 20 Nov.

    Show notes Swift's Last Orbit: NASA's burst hunter falls home, a gamma-ray burst that is two explosions in one, and 3I/ATLAS's dusty ice. Swift's Last Orbit NASA's Neil Gehrels Swift Observatory is expected to re-enter Earth's atmosphere on Wednesday 4 November; the US Space Force prediction is about 03:30 EST (08:30 UTC, 19:30 AEDT), plus or minus 11 hours. Surviving fragments are confined between 20.6°N and 20.6°S, a band that includes northern Australia; NASA puts the risk of harm to anyone at about 1 in 2,100. We look back at 22 years of science from a two-year mission: more than 2,000 gamma-ray bursts, the first short-burst afterglow in 2005, the BOAT in 2022, and about 7,000 papers. Two Bursts, Two Births GRB 160425A, caught by Swift in April 2016, is a 1.7-second short spike, four minutes of silence, then a 51-second long burst from the same place. A Nature Astronomy paper (Li, Wang, Zhang, Cai et al., 23 October; preprint March) argues the first is merger-like and the second collapsar-like. One event, no confirmed supernova or kilonova. 3I/ATLAS's Dusty Ice Webb's NIRSpec found the interstellar comet's ice grains are about a micron across and mixed with lots of dust, resembling some trans-Neptunian objects more than familiar comets (Protopapa et al., ApJL, 26 October; preprint September). Quick Hits Starship Flight 15 targeted NET 12 November per the FAA (unconfirmed by SpaceX); BepiColombo's Mercury orbit insertion on 21 November; Voyager 1 reaches one light-day around 18 November. Skywatch Venus near Spica before dawn, joined by a 5%-lit crescent Moon on Saturday 7 November; Mars and Jupiter closing to 1.2° by 16 November (high from the north); Saturn high in southern evening skies; New Moon 9 November; Leonids 17–18 November.

    Two black holes caught feeding side by side just 1.3 billion years after the Big Bang. JWST and ALMA confirm LID-1166, the first close dual AGN found beyond the nearby universe. Plus: Swift's final days and NASA's call for ideas to save Hubble, Rubin finds Neptune's missing trailing Trojans as Lucy enters Jupiter's, TRACERS' first look at where the solar wind gets in, and a both-hemispheres skywatch built around the Mars-Jupiter meeting on 16 November. Two Hearts in One Galaxy (LID-1166) JWST/NIRSpec integral-field spectroscopy resolves two feeding black holes ~1.5 kpc (~4,900 ly) apart at z~4.5; ALMA [CII] finds matching cold gas around each. Both appear super-Eddington yet already sit on the local black hole-host mass relation. One system, projected separation; preprint posted July, published in Nature Astronomy this week. Living on Borrowed Altitude Swift ended operations on 20 October and is expected to re-enter in early November. NASA's 29 October Request for Information asks industry about boosting, servicing or safely de-orbiting Hubble, likely to re-enter in 2033-34. Not a commitment; responses due 30 November. Trojan Week Rubin early data confirms 2025 MH348 and 2025 NN80 as long-lived trailing Neptune Trojans, plus candidate 2025 MD138 (Schwamb et al., ApJL). Lucy becomes the first spacecraft to enter the Jupiter Trojan region; Eurybates flyby 11 August 2027. TRACERS: Where the Solar Wind Gets In First results (JGR: Space Physics) suggest cusp reconnection is largely spatial rather than temporal. Mission extended to spring 2027. Quick hits BepiColombo Mercury orbit insertion 21 November; Starship Flight 15 targeted November with a double catch attempt; Voyager 1 one light-day from Earth around 18 November. Skywatch Mars and Jupiter 1.2 degrees apart before dawn on 16 November; Venus, a thin Moon and Spica low at dawn 7-10 November; Saturn high in southern evenings; zodiacal light around New Moon (9 Nov); Leonids 17-18 November; supermoon 24 November. ISO 12312-2 solar safety reminder.

    Space Nuts: The Great Attractor, What Makes a Moon, and Life Beneath the Rings

    In this listener Q&A episode of Space Nuts , Andrew Dunkley and Professor Fred Watson tackle a curious collection of cosmic questions. They explain why a crescent Moon can appear alongside the Sun in the morning sky, then explore the Great Attractor: the enormous concentration of galaxy clusters influencing the motion of our Local Group. The conversation turns to a lingering classification puzzle — what exactly makes a moon a moon, and should it have to clear its orbit? Finally, they imagine the view from a rocky world with rings, considering how the rings might look through the seasons, how sunlight would filter through them and what spectacular shadows or eclipses might occur. Join Andrew and Fred Watson for astronomy, imagination and the occasional tractor joke.

    Key topics

    - Why the Sun and a crescent Moon can be visible together in the morning sky.

    - The Great Attractor, the Zone of Avoidance and the Laniakea Supercluster.

    - Whether moons need to be spherical or clear their orbits, and the case of Pluto and Charon.

    - What a ringed planet might look like from its surface, including seasonal changes, shadows and eclipses.

    Electrons made on the wrong side of Earth's 'impenetrable barrier', a gamma-ray burst that only looked weak, the week that was, and a Halloween that is astronomically a week early. The Wall That Broke In 2014 NASA's Van Allen Probes revealed a sharp inner edge to Earth's outer radiation belt: electrons at the very highest energies never got closer than about 2.8 Earth radii. During the May 2024 superstorm — the biggest since the 2003 Halloween storms — Japan's Arase satellite saw electrons of about 3 MeV rise deep inside that 'impenetrable barrier'. A new paper led by Yoshizumi Miyoshi (Nagoya University ISEE) shows a peak in electron phase space density growing in place at L* ≈ 3, about 12,000 km up — evidence the electrons were accelerated there rather than carried in. Intense chorus waves, operating in a region emptied by a crushed plasmasphere and a negative ionospheric storm, are the likely engine. Caveats: one storm; 'consistent with' chorus acceleration; the breach itself had been reported before — the new part is the mechanism. Not Faint, Just Side-On GRB 260310A, caught by Fermi on 10 March 2026, had a feeble gamma-ray flash but one of the brightest afterglows ever seen. Yu-Han Yang (Tor Vergata) and colleagues argue we viewed a two-component jet from the side. Preprint from May; published in ApJL this month; competing models exist. The Week That Was E214 GRB 160425A, one burst with two births · E215 θ¹ Ori C, the star born twice · E216 Rubin's first dwarf-planet candidate 2026 ED138 · E217 Betelgeuse pulled out of round by Siwarha · E218 Teghaza 001, one of the oldest pieces of Mars. Plus Swift's re-entry watch, Voyager 1 at one light-day on 18 Nov, and Starship Flight 15 targeted for November. Skywatch Halloween is astronomically a week early (true cross-quarter 7 Nov). Mars, Jupiter and Regulus line up before dawn, Mars–Jupiter just over 1° apart on 16 Nov. Moon near Mars and Jupiter on the mornings of 2–3 Nov. Saturn rules the evening, best from the south. US clocks fall back 1 Nov. Solar viewing only with ISO 12312-2 certified filters.

    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.

    Space Nuts: Mars’ Moons, Martian Quakes, and the Search for ET

    In this engaging episode of Space Nuts , Andrew Dunkley and Professor Fred Watson explore two mysteries from Mars, along with a new effort to listen for signs of life beyond Earth. First, they unpack Japan’s Martian Moons eXploration (MMX) mission, which will study Phobos and Deimos, attempt a landing on Phobos and bring samples back to Earth. The discussion turns to a Marsquake traced to the immense Valles Marineris canyon, offering fresh clues that the Red Planet may still be geologically active. Finally, Andrew and Fred Watson examine Saudi Arabia’s plans for a major astronomical observatory, including a site for Laser SETI detectors searching for brief flashes of possible extraterrestrial communication. Join them for a cosmic tour filled with planetary puzzles, ambitious missions and a little speculation about how aliens might get in touch.

    Key topics

    - Japan’s MMX mission to investigate Mars’ moons and return samples from Phobos.

    - The possible origins of Phobos and Deimos, and the challenges of landing on a world with almost no gravity.

    - A Marsquake linked to Valles Marineris and what it suggests about the planet’s geological activity.

    - Saudi Arabia’s planned observatory and the use of optical Laser SETI detectors in the search for extraterrestrial signals.

    Astronomy Daily S05E216 — A New World in the Crowd (Thursday 29 October 2026). Hosts Anna and Avery. Lead: the Vera C. Rubin Observatory has found its first dwarf-planet candidate. 2026 ED138 lies beyond Pluto, about 46 au from the Sun. Matthew Holman (CfA) found it on 13 October with a search code built with Kevin Napier, and it was announced on 27 October at the DPS meeting in Spokane (MPEC 2026-U85). Rubin caught it 30 times on 20 nights between March and July, and Dark Energy Camera precoveries extend the orbit back to 2016. Only nine known trans-Neptunian objects are intrinsically brighter. Its size is estimated at 600–1,500 km, depending on reflectivity, so it remains a candidate until infrared or occultation measurements pin it down. It hid near the plane of the Milky Way, about 43° south of the celestial equator. Also: JWST's 37-hour phase curve shows the lava world TOI-561 b reflecting about three-quarters of its starlight, possibly through silicate clouds, with University of Sydney co-authors. ESA's Hera resolves Didymos and Dimorphos separately for the first time, with detailed Dimorphos images due 25 November. NASA's Swift is in its final weeks before re-entry, and UVEX passes a key review. Skywatch for Sydney, Los Angeles, New York and London: Mars and Jupiter closing in the pre-dawn sky (1.2° on 16 November), Saturn in the evening, Mercury's last call from the south, the waning Moon through Taurus to Gemini, and the US clock change on 1 November.

    Astronomy Daily S05E215 — The Star That Was Born Twice (Tuesday 27 October 2026). Hosts Anna and Avery. Lead: the Orion Nebula's age paradox. Its planet-forming discs and its expanding gas shell both look far younger than its million-year-old stars. Wilhelm, Trani and Portegies Zwart (Leiden / Universidad de Concepción) propose that the nebula's most massive star, θ1 Orionis C1, formed a few hundred thousand years ago when two stars merged, driven by their companion's gravity, suddenly switching on harsher radiation. We cover the caveats and the clean test that could falsify it. Also: WD J1328−1450, a white dwarf with two nested rings of gas that point to two hidden planetary bodies; China's AIMS telescope reads a solar flare's magnetic field directly in the mid-infrared; and a Yale study arguing giant impacts can help rocky planets keep hydrogen atmospheres. Quick hits: NASA's new Competition Model 2.0, Swift's mission formally ended ahead of re-entry, Hera's second braking burn, and the DPS meeting in Spokane. Skywatch: finding the Orion Nebula from Sydney, Los Angeles, New York and London; Saturn in the evening; Mercury's last call in the south; Mars and Jupiter converging before dawn.
