Mars Gullies Aren't Made by Water: The Surprising Dry Ice Answer
24 september 2026 · 33 min
Perseverance drove to the edge of an ancient Martian lake expecting a beach and found the inside of a volcano — rock that water has been through at least three separate times. Europe's Jupiter probe comes home on Monday night and crosses Australia in a fully dark sky. Two teams, using two completely different techniques, both find something hiding inside the most famous planetary system we have ever photographed — and an Australian instrument is in the middle of one of them. Plus: heavy water in an interstellar comet, and what it says about the star that made it. In this episode · LEAD — Three floods at the crater's edge. Candice Bedford (Purdue) and colleagues publish in Communications Earth & Environment: the Margin Unit at Jezero is igneous, not sedimentary, and records at least three distinct episodes of water — CO₂-rich groundwater making carbonate ridges, then silica associated with the lake, then a later hot-water event leaving fluorite veins. Habitability context, not a biosignature. · Juice returns. ESA confirms the third Earth gravity assist for 28 September — closest approach 11:45 UTC over the Indian Ocean, bending the trajectory ~20° and adding ~3.5 km/s. The spacecraft crosses Australia north-east to north-west 15–30 minutes earlier, in full darkness. · HR 8799. Two preprints in two weeks point at a fifth, inner planet — one from archival JWST aperture-masking data (~7 au, a few Jupiter masses), one from Gaia astrometry (2–3 au, 10–14 Jupiter masses). They do not obviously describe the same object. Neither is peer-reviewed. · 3I/ATLAS. A modelling paper explains the high deuterium-to-hydrogen ratio measured in March as consistent with formation around a low-metallicity — meaning old — star. · Quick hit: Starship Flight 14 still targeting 28 September; Crew-13 still 'no earlier than early October' on NASA's own page; Albania signs the Artemis Accords as the 73rd country. · Skywatch: the equinox as an instant rather than a date, the Juice pass over Aust… Lees meer

Space Nuts covers three very different space stories in this episode, ranging from planetary science to the consequences of satellite reentry and a controversial military uniform design. Andrew Dunkley and Professor Fred Watson also field listener questions on orbital mechanics, neutrinos, alien communication, and time dilation.
The discussion is broad, but the main thread is clear: how real-world physics shapes everything from Venus’s history to the future of spaceflight and even the look of space-age uniforms.
Key topics
Venus is Earth-like in size, mass, and gravity, but unlike Earth it has no moon, and the episode explores whether it may once have had one.
Fred explains a modeling study led by Stephen Kane suggesting a Venus moon could have spiraled inward, crossed the Roche limit, and been torn apart by tidal forces.
The team discusses what evidence might remain if Venus once consumed a moon, including possible chemical fingerprints in the atmosphere or surface.
Satellite pollution is examined through the lens of reentering spacecraft, especially the growing number of Starlink reentries and their impact on the upper atmosphere.
The European Space Agency’s jet-based chase of two reentering Cluster spacecraft, Tango and Samba, is described as an effort to measure reentry byproducts directly.
The conversation raises concerns about aluminium oxides, atmospheric chemistry, and whether repeated reentries could have broader consequences such as ozone depletion.
The final main story looks at proposed United States Space Force uniforms and why the design drew immediate comparisons to World War II-era fascist aesthetics and Starship Troopers.

Andrew Dunkley and Professor Fred Watson cover four big astronomy stories in this episode, from Fred’s trip to view a sunset eclipse in Spain to the launch of the Nancy Grace Roman Space Telescope. They also unpack a starless dwarf galaxy called Cloud Nine and a new way of thinking about the strange dark material in Venus’s clouds.
Guests and speakers
Andrew Dunkley - Host, frames the news, asks listener questions, and guides the discussion.
Professor Fred Watson - Astronomer at large, explains the eclipse, the Roman telescope, Cloud Nine, and Venus’s clouds.
Key topics
In this episode, Fred recounts the Spanish eclipse expedition
The eclipse was only 9 degrees above the western horizon at totality, making the viewing conditions unusually challenging.
He and Marnie led a 16-person tour through France, Spain, and Switzerland before settling near Santander in northern Spain.
They staked out a viewing site 2 kilometers from the hotel, set up a gazebo, and had to tie it down to a car to keep it from blowing away.
The weather looked threatening, but a hole opened in the cloud just before totality, giving them a clear view of the corona.
Fred described the yellowish corona, pink hydrogen clouds, and the crowd of around 2,000 people.
We discuss the Nancy Grace Roman Space Telescope launch
Andrew watched the launch live after being nudged by his own brain at the right moment.
Fred noted the launch was flawless, with 27 Merlin motors firing.
The telescope is headed for the L2 Lagrange point, about 1.5 million kilometers away.

The Galaxy’s Sugary Center Could Change How Life Began
13 augustus 2026 · 28 min
This episode covers three very different astronomy stories and then moves into a lively Q&A with listener questions. Andrew Dunkley and Professor Fred Watson discuss a possible sugary molecule in the center of the Milky Way, the risk lunar landers may contaminate ice that could preserve clues to life’s origins, and a new way to track lost dogs using satellite connectivity. The second half of the episode answers questions about moons with atmospheres, secret astronomy, hot Jupiters, and black hole mergers.
Key topics
In this episode, Fred Watson explains an update from Peter Verweyen on MOND, now referred to as Aether Scalar Tensor Theory, and how it relates to dark matter and dark energy debates.
We discuss the detection of erythrulose, a sugar molecule found in interstellar gas clouds near the center of the Milky Way, and why this matters for prebiotic chemistry.
Fred describes how molecules like sugar can form in cold molecular clouds before stars and planets exist, making some ingredients for life surprisingly common.
We discuss a new study warning that rocket exhaust from future lunar landings could contaminate ice in permanently shadowed craters at the Moon’s south pole.
The Moon’s polar ice may contain ancient prebiotic molecules delivered by comets, asteroids, and dust, making it a possible time capsule for the chemistry that led to life.
We discuss the practical and ethical problem that landers have to use rocket engines, and those exhaust plumes may spread methane and other organics across the lunar surface very quickly.
Fred shares how satellite-based direct-to-cell or direct-to-mobile systems could help locate lost dogs in remote places without cell coverage.
We discuss how this kind of tracking builds on existing GPS pet trackers, and how it could be useful in wilderness areas, while also noting the limits and concerns in national parks.
