  • Snowball Earth Evidence, Blue Origin's Parachute Mishap, and the Moon's Horizon Illusion: S28E23

    Snowball Earth Evidence, Blue Origin's Parachute Mishap, and the Moon's Horizon Illusion: S28E23
    Feb 21 2025
    SpaceTime Series 28 Episode 23
    The Astronomy, Space and Science News Podcast
    Snowball Earth Evidence, Blue Origin's Parachute Failure, and the Moon Illusion Explained
    In this episode of SpaceTime, we dive into groundbreaking geological research that provides compelling evidence for the Snowball Earth hypothesis, suggesting that glaciers may have covered the planet from pole to pole hundreds of millions of years ago. This research reveals insights into Earth's climatic history and the emergence of multicellular life following this extreme glaciation event.
    Blue Origin's Lunar Gravity Mission
    We also discuss the recent Blue Origin mission, where the New Shepard spacecraft experienced a parachute failure during a lunar gravity simulation flight. Despite the malfunction, mission managers confirm that the capsule was designed to land safely with two parachutes, and investigations are underway to understand the issue.
    The Moon Illusion: Why Does It Appear Larger on the Horizon?
    Additionally, we explore the fascinating phenomenon known as the Moon illusion, which causes the Moon to appear larger when it is near the horizon compared to when it is high in the sky. We delve into the psychological and perceptual factors that contribute to this optical illusion, despite the Moon's actual size remaining constant.

  • Van Allen's New Belts, Alien Oceans and Life, and Massive Black Hole Jets Uncovered: S28E22

    Van Allen's New Belts, Alien Oceans and Life, and Massive Black Hole Jets Uncovered: S28E22
    Feb 19 2025
    SpaceTime Series 28 Episode 22
    The Astronomy, Space and Science News Podcast
    New Van Allen Radiation Belts, Alien Oceans and Signs of Life, and the Largest Black Hole Radio Jet Ever Detected
    In this episode of SpaceTime, we uncover the discovery of two new temporary Van Allen radiation belts created by a massive solar storm that struck Earth in May 2024. This event not only produced stunning auroras but also highlighted the importance of understanding the dynamics of radiation belts for the safety of satellites and astronauts. The findings, reported by NASA's Colorado Inner Radiation Belt Experiment, reveal that these belts can last significantly longer than previously thought, with implications for future solar storms and spaceflight safety.
    Searching for Life in Alien Oceans
    We also explore the challenges of detecting signs of extraterrestrial life in the subsurface oceans of icy moons like Saturn's Enceladus. A new study suggests that the unique physics of these oceans could hinder the movement of biological signatures from deep waters to the surface, complicating the search for life beyond Earth. This research emphasizes the need to understand ocean dynamics in the search for life in our solar system.
    The Largest Black Hole Radio Jet in the Early Universe
    Additionally, astronomers have identified the largest radio jet ever seen in the early universe, spanning an astonishing 200,000 light years. This discovery sheds light on the formation of massive jets and quasars, providing crucial insights into the evolution of galaxies in the early cosmos. The quasar, which formed when the universe was just 9% of its current age, challenges previous assumptions about the conditions needed for such powerful jets to form.

    The Astronomy, Space and Science News Podcast
    Shifting Dynamics of Earth's Inner Core, China's Lunar South Pole Mission, and Insights into Hot Jupiter Exoplanets
    In this episode of SpaceTime, we explore groundbreaking research revealing that Earth's inner core may be less solid than previously believed. A new study indicates that the near surface of the inner core is undergoing structural transformations, influenced by interactions with the turbulent outer core. This discovery provides fresh insights into the dynamics of Earth's core and its impact on the planet's magnetic field and rotation.
    China's Chang'e 7 Mission: A Quest for Lunar Water Ice
    We also discuss China's upcoming Chang'e 7 mission, set to launch next year, which aims to search for water ice at the lunar south pole. This mission will employ advanced technologies to locate and analyze water ice deposits, crucial for supporting future manned missions to the Moon and beyond. The Chang'e 7 mission will include an orbiter, lander, rover, and a mobile hopper designed for traversing shadowed craters.
    Hot Jupiter Progenitor: New Discoveries in Exoplanet Research
    Additionally, we delve into the fascinating discovery of a hot Jupiter exoplanet with an eccentric orbit, shedding light on the formation processes of these gas giants. The research indicates that this planet has likely been influenced by a binary star system, providing new evidence for the mechanisms behind hot Jupiter migration and evolution.
