Cosmic Discoveries: Erupting Comets, Boiling Ice Moons, and Mars' Climate Secrets

In this captivating episode of Space Nuts , hosts Andrew Dunkley and Professor Fred Watson delve into the latest astronomical revelations that are reshaping our understanding of the cosmos. From the surprising eruptions of the exo-comet 3I Atlas to the intriguing boiling oceans beneath the icy crusts of moons like Enceladus, this episode is filled with cosmic wonders.

Episode Highlights:

- Eruptions on Comet 3I Atlas: Andrew and Fred explore the recent findings about the interstellar comet 3I Atlas, which appears to be experiencing volcanic eruptions. They discuss the concept of cryovolcanoes and how the comet's interactions with solar radiation may be causing these fascinating phenomena.

- Boiling Oceans of Ice Moons: The hosts examine new research from the University of California, Davis, which suggests that the ice moons of our solar system, including Enceladus, may have boiling oceans beneath their icy crusts. They explain how tidal forces and pressure changes could lead to this unexpected behavior.

- New Evidence of Mars' Climate: Andrew and Fred discuss exciting discoveries made by NASA's Perseverance rover, which has found evidence of a wet, tropical climate on Mars billions of years ago. They delve into the implications of these findings and what they might mean for the potential of past life on the Red Planet.

- Launch Pad Mishap: The episode concludes with a discussion about the recent incident involving the Soyuz launch pad, where a service platform was damaged following a successful launch. The hosts reflect on the challenges faced in human spaceflight and the ongoing cooperation between international space agencies despite geopolitical tensions.

In this episode of SpaceTime , we explore groundbreaking discoveries and intriguing phenomena from Mars to the depths of space.

Lightning Strikes on Mars: A Historic Discovery

NASA's Perseverance Rover has made a remarkable find by detecting lightning in the Martian atmosphere for the first time. Recorded within two dust devils in Jezero Crater, the rover's Supercam microphone captured electromagnetic and acoustic signals indicative of electrical discharges. This discovery not only confirms long-held theories about Martian electrical activity but also reveals significant implications for the planet's atmospheric chemistry and potential hazards for future missions.

NASA's Observations of Interstellar Comet 3I Atlas

Following the European Space Agency's observations, NASA has released stunning images of interstellar comet 3I Atlas. As the comet passed close to Mars, NASA's MAVEN and Mars Reconnaissance Orbiter provided crucial data on its trajectory and chemical composition. These insights are helping astronomers piece together the comet's journey and origins, revealing potential clues about water in other star systems.

Moss in Space: Resilience Against the Void

A new study has shown that moss can survive the harsh conditions of space for up to 15 years. Researchers sent moss spores to the International Space Station, where they thrived despite exposure to the vacuum and extreme temperatures. This remarkable resilience could have implications for understanding life's potential to endure in extreme environments beyond Earth.

Skywatch: December Highlights

As the December solstice approaches, we take a look at the night sky's highlights, including the Geminids meteor shower and the ticking time bomb of Eta Carina. We also discuss the significance of the December solstice and the celestial events that define this time of year.

Threat to the Atacama Desert: Scientists are raising alarms over a massive renewable energy project near Chile’s Atacama Desert, home to the Paranal Observatory. Concerns include potential light pollution, dust interference, and atmospheric heating that could compromise the region's exceptional astronomical conditions. The scientific community is advocating for solutions to minimize these impacts while balancing sustainable energy needs.

Blue Origin's New Innovations: Blue Origin has unveiled exciting new hardware, including the Blue Moon Mark One robotic lander set to fly by 2026, a more powerful version of the New Glenn rocket, and Blue Ring, a space tug designed to support logistics in Earth orbit. These advancements highlight the company's commitment to building a sustainable space infrastructure.

Starquakes and Cosmic Mysteries: NASA's TESS has detected unusual starquakes from a red giant orbiting the black hole Gaia BH2. The star's rapid spin and curious chemical composition suggest it may be the result of a merger between two stars, showcasing the power of astroseismology in uncovering cosmic histories.

Time on Mars: A fascinating revelation indicates that time moves slightly faster on Mars compared to Earth due to its weaker gravity and slower orbit. This difference, while minuscule, poses significant implications for future Martian missions, necessitating a standardized time system for coordinated operations.

Innovative Martian Construction: Researchers propose a groundbreaking method for building on Mars using local resources. By combining Martian soil with Earth bacteria, scientists aim to create bioconcrete for construction, while also producing oxygen, offering a dual solution for habitat creation and life support in the harsh Martian environment.
