  • Celestial Discoveries: The Oldest Comet, Pulsar Insights, and Axiom Space's Successful Splashdown

    Celestial Discoveries: The Oldest Comet, Pulsar Insights, and Axiom Space's Successful Splashdown
    Jul 25 2025
    In this episode of SpaceTime, we explore the latest cosmic revelations, including the astonishing discovery of an ancient interstellar comet, the intricate workings of a rare pulsar, and the safe return of the Axiom 4 crew from their mission.
    Ancient Interstellar Comet 3I/Atlas
    Astronomers have unveiled that the newly discovered interstellar object, 3I/Atlas, could be the oldest comet ever observed, potentially predating our solar system by over 3 billion years. This water-rich visitor, detected by NASA's ATLAS survey, is only the third known object from beyond our solar system to reach us. A study by Matthew Hopkins from Oxford University suggests that 3I/Atlas may be more than 7 billion years old, offering a glimpse into a part of the Milky Way previously unseen. As it approaches the sun, its activity is expected to increase, revealing more about its composition and the role ancient comets play in star and planetary formation.
    Unraveling the Mysteries of a Rare Pulsar
    In another exciting development, astronomers have made significant strides in understanding a unique pulsar system, PSRJ 1023 0038. This transitional millisecond pulsar, which interacts with a lower mass stellar companion, has been studied using data from NASA's Imaging X-Ray Polarimetry Explorer (IXPE). The findings suggest that the X-ray emissions originate from the pulsar wind rather than the accretion disk, challenging existing models and providing new insights into neutron star behavior and particle acceleration.
    Axiom Space AX4 Crew Returns
    The Axiom Space AX4 crew has successfully splashed down in the North Pacific Ocean after nearly three weeks aboard the International Space Station. This mission, part of NASA's efforts to promote commercial activities in space, included a diverse crew and numerous scientific experiments. With the return of the AX4 crew, preparations are underway for NASA's upcoming Crew 11 mission, further expanding humanity's presence in low Earth orbit.

    In this episode of SpaceTime, we delve into groundbreaking discoveries that reveal the impact of human activity on Earth, explore a new celestial body beyond Pluto, and prepare for Japan's upcoming Martian moon mission.
    Human Development and Earth's Polar Shift
    A recent study published in Geophysical Research Letters has confirmed that human development has caused a significant shift in Earth's spin axis. By constructing nearly 7,000 dams between 1835 and 2011, humans have redistributed the planet's mass, resulting in a total pole shift of about 1.13 meters. Lead author Natasha Valencic explains how this shift not only affects Earth's rotation but also contributes to a global drop in sea levels. The findings underscore the importance of considering water impoundment in future sea level rise calculations.
    Discovery of a World Beyond Pluto
    Astronomers have identified a small celestial object, designated 2023 KQ14, located beyond Pluto, potentially challenging the existence of the elusive Planet Nine. This discovery, detailed in Nature Astronomy, suggests that the outer solar system is more diverse than previously thought. With a stable orbit for over 4.5 billion years, 2023 KQ14's peculiar trajectory raises questions about the formation and evolution of distant solar system bodies, as well as the dynamics of gravitational influences in this remote region.
    Japan's Martian Moon Sample Return Mission
    Japan's aerospace exploration agency JAXA is set to launch the Martian Moons Exploration Mission (MMX) in 2026. This ambitious mission aims to land on Phobos, collect samples, and return them to Earth by 2031. The spacecraft will also conduct a flyby of Deimos while gathering crucial data to determine the origins of Mars' moons. With advanced scientific instruments onboard, the mission seeks to unravel the mysteries surrounding these small, potato-shaped moons and their relationship to the Red Planet's history.

  • Cosmic Origins: Cracking the Matter-Antimatter Mystery and Witnessing a New Solar System

    Cosmic Origins: Cracking the Matter-Antimatter Mystery and Witnessing a New Solar System
    Jul 21 2025
    In this episode of SpaceTime, we tackle some of the most profound questions in science, including the mystery of why the universe exists, the potential for liquid water on Mars, and the birth of a new solar system.
    Unraveling the Mystery of the Universe
    Scientists have made significant strides in understanding the fundamental differences between matter and antimatter, a question that has puzzled humanity since the dawn of physics. The LHCB collaboration at CERN has provided compelling evidence of a mirror-like asymmetry in how baryons behave compared to their antimatter counterparts. This breakthrough could shed light on why our universe is predominantly composed of matter, despite the equal creation of matter and antimatter during the Big Bang. We delve into the implications of this discovery and its potential to unlock the secrets of the universe's existence.
    Liquid Water on Mars: A New Possibility
    A groundbreaking study suggests that liquid brines may form on the Martian surface, challenging the long-held belief that Mars is devoid of liquid water. Lead researcher Vincent Chevrea from the University of Arkansas discusses how meteorological data and advanced computer modeling indicate that brines could develop during specific seasonal windows. This finding opens new avenues for the search for life on Mars and highlights the importance of targeting these periods for future exploration.
    Witnessing the Dawn of a New Solar System
    Astronomers have made an unprecedented observation of a new solar system forming around the protostar HOPS 315, located 1300 light-years away. Using the Atacama Large Millimeter/Submillimeter Array (ALMA), researchers have identified the very first specks of planet-forming material, marking a significant milestone in our understanding of solar system formation. This discovery not only provides insight into the processes that shaped our own solar system 4.6 billion years ago but also offers a unique opportunity to study planetary formation in real-time.
