SpaceTime Series 27 Episode 115
*How Black Holes Eat Stars
Astronomers have developed a groundbreaking computer simulation detailing how supermassive black holes at the centres of galaxies can rip apart and consume entire stars. The study, published in the Astrophysical Journal Letters, provides new insights into the mysterious optical and ultraviolet emissions observed during these catastrophic events. Lead author Daniel Price from Monash University explains that the simulation captures the full evolution of the debris from a star being tidally disrupted by a black hole.
*New Revelations About Earth’s Mantle
A new study reveals that the chemical composition of the Earth's mantle is uniform globally and only changes as it passes through different layers of crust closer to the planet's surface. Reported in the journal Nature Geoscience, the findings suggest that lavas from volcanic hotspots around the world likely originate from a worldwide uniform reservoir in the Earth's mantle.
*Water More Widespread on the Moon Than Previously Thought
New maps from both the near and far sides of the Moon show that the lunar surface contains vast amounts of water, mostly locked in the lunar regolith. The findings, published in the Planetary Science Journal, suggest multiple sources of water and hydroxyl in sunlit rocks and soils, including water-rich rocks excavated by meteor impacts at all lunar latitudes.

SpaceTime Series 27 Episode 114
*Did the Dwarf Planet Ceres Originate in the Asteroid Belt? A new study challenges earlier observations about the origins of Ceres, the largest body in the main asteroid belt. The findings suggest that Ceres may have formed where it currently orbits rather than in the outer solar system.
*Galactic Mystery About Dark Matter and Stars Finally Resolved Astronomers have overturned a longstanding idea that stars and dark matter interact in inexplicable ways. New models suggest that the similarity in density structures across different galaxies might be due to previous oversimplified modelling rather than an actual interaction between stars and dark matter.
*China's Secretive Space Plane Returns to Earth China's experimental reusable spacecraft has completed a 268-day orbital mission. While Beijing claims the mission was for peaceful Space operations, the spacecraft appeared to be inspecting other satellites, raising questions about its true purpose.

In today’s episode, we explore the latest discoveries in lunar volcanism, the unique phenomena awaiting astronauts at the moon's south pole, and the arrival of a new crew at the International Space Station. Join us for an in-depth look at these exciting developments in Space exploration!
*Recent volcanism on discovered on the Moon Scientists have discovered evidence of volcanism on the lunar surface as recently as 125 million years ago. *The Strange phenomena people will see at Moon's south pole When astronauts return to the Moon’s surface as part of the Artemis 3 mission to the Lunar south pole, they’ll experience a very different environment to that which the Apollo astronauts witnessed more than half a century ago. *A new crew arrives at the International Space Station The Russian Soyuz MS-26 capsule has successfully docked with the International Space station just three hours after its launch aboard a Soyuz 2.1a rocket from the Baikonur Cosmodrome in in the central Asian republic of Kazakhstan. *The Science Report Study shows up to 19% of dementia cases could be linked to vision problems. Over 52 million tonnes of plastic dumped into the environment every year. The growing amount of incorrect AI generated data being generated. Alex on Tech: are the new iPhone 16s worth it?

SpaceTime Series 27 Episode 112
First Ever Spacewalk by Private AstronautsA historic milestone as the first commercial non-government astronauts successfully complete a spacewalk using a SpaceX Dragon capsule. The mission, launched aboard a Falcon 9 rocket, aimed to monitor radiation exposure levels during its journey into the Van Allen radiation belts.
Boeing Starliner Returns Safely to EarthBoeing's trouble-plagued Starliner spacecraft has safely returned to Earth, landing unmanned at the White Sands Missile Range in New Mexico. NASA opted for an unmanned return due to ongoing safety concerns with the spacecraft.
*Asteroid Creates Spectacular Fireball Over the Philippines: A small asteroid created a stunning fireball as it entered Earth's atmosphere over the Philippines. The asteroid, designated 2024 RW1, was detected just hours before its atmospheric entry, providing a dazzling light show without causing any harm.
