  The Starless Galaxy That Shouldn’t Exist - But Does 03.09.2026 38min

  Space Nuts: Spanish Eclipse, Nancy Grace Roman Launch, Cloud Nine, and Venus's Mysterious CloudsAndrew 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 speakersAndrew 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 topicsIn this episode, Fred recounts the Spanish eclipse expeditionThe 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 launchAndrew 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.Roman is a 2.4-meter Hubble-class telescope but with 100 times the field of view.Its wide-angle infrared design should enable major surveys of dark matter, dark energy, and exoplanets via its coronagraph.Fred explains why Cloud Nine mattersCloud Nine is described as a starless dwarf galaxy about 14 million light years away.It lies near Messier 94 and was studied using the Gran Telescopio Canarias and its Hypercam instrument.The deep exposure was 2.36 hours, yet the team found no convincing stellar population.Fred says theory suggests the gas may be too hot to cool and collapse into stars because of the ultraviolet background radiation after reionization.He says Cloud Nine may be the first strong example of a galaxy predicted by standard cosmology but never before clearly identified.Venus’s clouds are still puzzling astronomersFred explains that Venus appears yellowish because we see the top of its cloud layer, especially in visible light.In ultraviolet, Venus shows dramatic global cloud patterns caused by an as-yet unidentified absorber.The new study uses radiative transfer modeling to constrain what the unknown absorber could be.The team compares Venus’s cloud droplets to cigarette smoke, tiny particles that look light-colored when dispersed but could become dark sludge in bulk.The result suggests the absorber must be very efficient, very concentrated, or both, but it is not being claimed as evidence of life.Become a supporter of this podcast: https://www.spreaker.com/podcast/space-nuts-astronomy-insights-cosmic-discoveries--2631155/support.

  The Galaxy’s Sugary Center Could Change How Life Began 13.08.2026 27min

  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 topicsIn 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.Timestamps(00:00) Start of the episode and what’s coming up(03:12) MOND update and the new AEST name(07:10) A sugary molecule in the center of our galaxy(09:51) Why sugar can form in deep space before stars exist(12:24) Why lunar landings could contaminate the Moon’s ice(14:54) The Moon as a time capsule for prebiotic molecules(16:24) Methane exhaust and rapid contamination risk(18:37) Should the Moon be protected like a national park?(20:28) Satellite tracking for lost dogs in remote areas(24:52) Direct-to-mobile satellite technology explained(25:44) The Judas goat program and invasive species controlBecome a supporter of this podcast: https://www.spreaker.com/podcast/space-nuts-astronomy-insights-cosmic-discoveries--2631155/support.
