  • S27E131: Milky Way's Gamma Ray Mystery, Triple Black Hole Discovery, and NASA's Solar Array Setback

    S27E131: Milky Way's Gamma Ray Mystery, Triple Black Hole Discovery, and NASA's Solar Array Setback
    Oct 30 2024
    SpaceTime Series 27 Episode 131
    *Ultra High Energy Gamma Rays Detected in the Milky Way's Core
    Scientists have detected ultra high energy gamma rays emanating from the centre of the Milky Way. This discovery, reported in the Astrophysical Journal Letters, offers a new perspective on the violent phenomena occurring in the galactic core. Using the High Altitude Water Cherenkov Observatory in Mexico, researchers measured these gamma rays at over 100 tera electron volts, providing insights into the cosmic processes involving Sagittarius A, the galaxy's central supermassive black hole.
    *Discovery of a Potential Triple Black Hole System
    Astronomers have identified what may be the first triple black hole system, located 8,000 light years away. This discovery could be the first direct evidence of gentle black hole formation, challenging the typical violent supernova origin theory. The system includes a central black hole, a closely orbiting star, and a far-off companion star, suggesting a more subtle formation process known as direct collapse.
    *NASA's New Deployable Solar Array System Faces Challenges
    NASA has encountered issues with its new deployable solar array and antenna system on the Pathfinder Technology Demonstrator 4 spacecraft. The lightweight integrated solar array and antenna system, designed to enhance power and communication capabilities, is not deploying correctly due to a bent boom. This technology aims to support future deep Space missions with improved efficiency.
    The Science Robert
    A recent study reveals that standing, as opposed to sitting, does not improve cardiovascular health, despite the popularity of standing desks. Fossilised remains of a new giant elephant species have been found in India's Kashmir Valley, shedding light on elephant evolution. AI-assisted colonoscopies show a slight improvement in polyp detection. Meanwhile, Apple releases its first AI update, focusing on privacy and user data protection.

  • S27E130: Universe's Early Light, Venusian Mysteries Unveiled, and China's Satellite Success

    S27E130: Universe's Early Light, Venusian Mysteries Unveiled, and China's Satellite Success
    Oct 29 2024
    SpaceTime Series 27 Episode 130
    *Epoch of Reionization: New Insights from Webb
    A groundbreaking study suggests the epoch of reionization, a pivotal era in the universe's early evolution, may have occurred 350 million years earlier than previously believed. Utilising data from the James Webb Space Telescope, astronomers have uncovered a greater abundance of extreme ultraviolet emitting galaxies, challenging established models. This revelation might imply that the cosmic microwave background radiation and the Lyman alpha forest should appear different, posing a conundrum for scientists and opening new avenues for understanding the universe's history.
    *NASA's DaVinci Mission Prepares for Venus
    NASA's upcoming DaVinci mission aims to explore Venus's enigmatic Alpha Regio, a mountainous region shrouded in mystery. The mission, set for the early 2030s, will delve into whether Venus once harboured oceans and continents, akin to Earth. By reanalysing old data and employing modern techniques, scientists have enhanced the resolution of Venus's topography, offering fresh insights into its geological features and potential volcanic activity. DaVinci's descent probe will capture unprecedented high-resolution images, potentially revealing new details about Venus's surface.
    *China's First Reusable Satellite Test
    China has successfully tested its first reusable satellite, the SHY119, launched aboard a Long March 2D rocket. Recovered after 13.5 days, the mission included various payloads, such as plant seeds and technology demonstration devices. This achievement marks a significant milestone in China's Space exploration efforts, showcasing advancements in reusable satellite technology.
    The Science Robert
    A study links hearing loss in older age to an increased risk of Parkinson's disease, with effective management through hearing aids potentially mitigating this risk. In the South Australian outback, palaeontologists have discovered one of Earth's earliest life forms, dating back 550 million years. Meanwhile, a new study warns that up to 33% of frog and toad habitats could become arid by the century's end due to climate change. Additionally, a Gallup poll reveals a significant drop in support for childhood vaccinations in the US, raising concerns about herd immunity.

  • S27E129: Martian Volcanic Discovery, Exomoon's Volcanic Cloud, and Solar Maximum's Impact

    S27E129: Martian Volcanic Discovery, Exomoon's Volcanic Cloud, and Solar Maximum's Impact
    Oct 25 2024
    SpaceTime Series 27 Episode 129
    *First Evidence of a Volcanic Splatocone on Mars
    Scientists have identified what appears to be the first evidence of a volcanic splatter cone on Mars, similar to those found on Earth. This discovery, led by Ian Flynn from the University of Idaho, sheds light on the volcanic processes of the red planet. The presence of splatter cones, which form under specific conditions, provides new insights into Martian volcanology and the dynamics of volcanic eruptions.
    *Volcanic Moon Around a Distant Exoplanet?
    A new study suggests the presence of a volcanic exomoon orbiting the exoplanet WASP 49 b, located 635 light years away. The discovery is based on a sodium cloud detected near the planet, resembling the volcanic activity seen on Jupiter's moon Io. This potential exomoon could offer a new perspective on moons outside our solar system, although further observations are needed to confirm its existence.
    *Sun Reaches Solar Maximum
    The sun has reached the solar maximum of its 11-year cycle, marking a peak in solar activity. This period is characterised by increased sunspots and Space weather events, impacting satellites, communication systems, and power grids on Earth. NASA's Parker Solar Probe is set to make its closest approach to the sun, providing valuable data to understand solar weather at its source.
    The Science Robert
    A new study finds that the rise in human life expectancy is slowing down. Research reveals that even low-risk alcohol consumption is linked to higher mortality in older adults with health or socioeconomic risk factors. Thawing permafrost may accelerate Arctic riverbank erosion, and Australia's proposed misinformation bill raises concerns about freedom of speech and censorship.
