To find out more visit squarespace.com/spacetime (https://squarespace.com/spacetime) SpaceTime with Stuart Gary Gary - Series 29 Episode 23 In this episode of SpaceTime, we investigate the discovery of a nearly invisible galaxy dominated by dark matter, the latest delays in the Artemis 2 mission to the Moon, and the anticipated launch of Australia's new hypersonic scramjet. A Dark Matter Galaxy Unveiled Astronomers have identified an almost invisible galaxy, catalogued as CDG2, located in the Perseus galaxy cluster approximately 300 million light years away. This galaxy is believed to be composed of about 99% dark matter, making it one of the most dark matter-dominated galaxies ever detected. The findings, published in Astrophysical Research Letters, reveal that dark matter constitutes roughly 80% of the universe's total matter, and CDG2's faint presence was confirmed through observations of its globular clusters using NASA's Hubble Space Telescope and the European Space Agency's Euclid Space Observatory. Artemis 2 Mission Delayed Again NASA has announced another delay for the Artemis 2 mission, which aims to return humans to lunar orbit for the first time in over 50 years. A helium leak discovered in the Space Launch System (SLS) rocket's upper stage has prompted the agency to roll back the launch vehicle to the vehicle assembly building for repairs. This setback eliminates the potential for a March launch, with the next available windows opening in early April. The Artemis 2 mission will carry a crew of four on a 10-day journey to the Moon, including critical system tests and satellite deployments. Australia's Hypersonic Scramjet Launch Imminent An Australian company is set to test its new hypersonic scramjet-powered aircraft, the Dart AE, before the end of the month. This innovative vehicle will utilize a 3D printed Spartan Scramjet engine, designed to operate at speeds exceeding Mach 5 with liquid hydrogen fuel. The mission, codenamed Cassowary Vex, will launch aboard a Rocket Lab electron rocket and aims to validate the scramjet propulsion system under real hypersonic flight conditions while producing zero carbon emissions. www.spacetimewithstuartgary.com (https://www.spacetimewithstuartgary.com/) ✍️ Episode References Astrophysical Research Letters Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-with-stuart-gary--2458531/support (https://www.spreaker.com/podcast/spacetime-with-stuart-gary--2458531/support?utm_source=rss&utm_medium=rss&utm_campaign=rss) .

Primordial Black Holes and Saturn’s Ring Origins: Unveiling Cosmic Mysteries

SpaceTime with Stuart Gary Gary - Series 29 Episode 22 In this episode of SpaceTime , we delve into the formation of the universe's most enigmatic objects, explore the origins of Saturn's iconic rings, and get updates on NASA's Artemis 2 mission. Black Holes and Exotic Cosmic Structures A groundbreaking study suggests that some of the universe's most exotic entities, including black holes and cannibal stars, may have formed just seconds after the Big Bang. Researchers from the International School of Advanced Studies propose that subatomic particles condensed into halos of matter, which then collapsed to create these fascinating cosmic structures. Their findings, published in Physical Review D, indicate that even in the earliest moments of the universe, complex physical phenomena were already taking shape, paving the way for our understanding of cosmic evolution. The Formation of Saturn's Rings New research proposes that Saturn's largest moon, Titan, may have formed from the collision of two older moons, potentially linking this event to the creation of Saturn's spectacular ring system. The study, reported in the Planetary Science Journal, utilizes computer simulations to explore the dynamics of Saturn's moons and their interactions, suggesting that Titan's merger could explain its unique orbit and the age of the rings, estimated to be around 100 million years. NASA's Artemis 2 Mission Update Following the recent scrubbing of the Artemis 2 launch due to hydrogen leaks, NASA has made significant repairs and is preparing for another attempt. Engineers have replaced seals in the mobile launcher's umbilical area and are conducting further testing to ensure the rocket's readiness. With multiple launch windows available in March, the Artemis 2 mission aims to test key systems aboard the Orion spacecraft, setting the stage for future lunar exploration and the eventual return of humans to the Moon. www.spacetimewithstuartgary.com (https://www.spacetimewithstuartgary.com/) ✍️ Episode References Physical Review D, Planetary Science Journal Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-with-stuart-gary--2458531/support (https://www.spreaker.com/podcast/spacetime-with-stuart-gary--2458531/support?utm_source=rss&utm_medium=rss&utm_campaign=rss) .

Exploring Life’s Potential on the Red Planet and Saturn’s Tiny Moon

SpaceTime with Stuart Gary Gary - Series 29 Episode 21 In this episode of SpaceTime , we explore intriguing revelations about the search for life on Mars, the surprising effects of Saturn's moon Enceladus on its planet, and the monumental volcanic events that reshaped Earth's tectonic landscape. Life on Mars: A New Perspective Recent findings suggest that non-biological processes cannot fully explain the organic compounds found in Martian regolith samples collected by NASA's Curiosity rover. Published in the journal Astrobiology, the study indicates that life may have contributed to some of these compounds, challenging previous assumptions. The research involved evaluating potential non-biological sources and concluded that the abundance of organics on Mars could hint at past life, sparking renewed interest in the Red Planet's potential habitability. Enceladus' Electromagnetic Influence A fascinating study reveals that Saturn's icy moon Enceladus trails a wake of electromagnetic ripples extending over half a million kilometers, significantly influencing its giant host planet. Data from NASA's Cassini mission demonstrated how Enceladus' geysers contribute to energy and momentum circulation within Saturn's magnetic environment, marking a crucial discovery about the moon's role in the Saturnian system. Earth's Volcanic History New research highlights how Earth's largest volcanic event, associated with the Ontong Java Plateau, dramatically altered a major tectonic plate. The findings suggest that extensive volcanic activity led to significant physiochemical modifications within the oceanic plate, enhancing our understanding of plate formation processes and the environmental impacts of such massive eruptions. www.spacetimewithstuartgary.com (https://www.spacetimewithstuartgary.com/) ✍️ Episode References Astrobiology, Geophysical Research Space Physics, Geophysical Research Letters Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-with-stuart-gary--2458531/support (https://www.spreaker.com/podcast/spacetime-with-stuart-gary--2458531/support?utm_source=rss&utm_medium=rss&utm_campaign=rss) .

Moon Hides Mercury Tonight, Artemis II Tests Tomorrow, Saturn Ring Origin Revealed

Episode: S05E42 — Wednesday, February 18, 2026 Hosts: Anna & Avery Network: Bitesz.com Podcast Network In today's episode of Astronomy Daily, Anna and Avery cover six unmissable stories from across the cosmos. Here's what we're talking about in S05E42: 1. Artemis II Wet Dress Rehearsal Round Two NASA begins fuelling the SLS moon rocket tomorrow (Feb 19) for a second critical practice countdown. Engineers have replaced two seals and a filter after hydrogen leaks forced the February launch window to be abandoned. A clean test is required before NASA will commit to a launch date — currently no earlier than March 6. The four-person crew includes Victor Glover, Christina Koch, and Jeremy Hansen, each of whom will make history on the flight. 2. Moon Occults Mercury Tonight — Plus a Ganymede Transit Tonight, February 18, a thin crescent Moon passes so close to Mercury that observers in Arizona, New Mexico, Texas, Louisiana, Mississippi, and Georgia will see the Moon hide Mercury in a rare occultation. For everyone else, a stunning close conjunction is visible in the western sky just after sunset. Simultaneously, Jupiter's moon Ganymede transits the gas giant's face through the night. Two events, one evening. 3. Ariane 6 Launches Amazon Kuiper Satellites Europe's most powerful Ariane 6 configuration successfully launched 32 satellites for Amazon's Project Kuiper broadband constellation today — a direct competitor to SpaceX's Starlink. The launch highlights both the commercial ambitions of Amazon's internet satellite programme and the ongoing resurgence of European launch capability. 4. 3I/ATLAS Update: JUICE Data Downlinking Now ESA's JUICE spacecraft is currently transmitting data it collected on interstellar comet 3I/ATLAS back to Earth — the downlink window runs February 18–20. If successful, this would be the closest-ever spacecraft observations of an interstellar object. Meanwhile, 3I/ATLAS heads toward a close Jupiter flyby in March that may trigger fresh outbursts. 5. How Titan Formed — And Why Saturn Has Rings New research from the SETI Institute proposes a single ancient catastrophe that explains multiple Saturn mysteries at once: a moon called proto-Hyperion collided with proto-Titan about 400 million years ago. The merger debris re-accreted into Saturn's inner moons and left behind the iconic ring system. The hypothesis also explains Saturn's unusual axial tilt, Iapetus's orbital inclination, and the surprising youth of Titan's surface. 6. Russia's 30-Day Mars Engine Rosatom's Troitsk Institute is ground-testing a nuclear-powered magnetoplasma engine that its developers claim could reach Mars in 30 days — compared to 8 months for chemical rockets. With a plasma exhaust velocity of 100 km/s, the system is part of a global race toward deep-space plasma propulsion also being pursued by NASA's VASIMR programme and Chinese researchers. A flight prototype is targeted for 2030.
