SpaceTime Series 27 Episode 140

*Revisiting the Milky Way's Black Hole Image

A new study questions the accuracy of the first-ever image of Sagittarius A, the supermassive black hole at the centre of the Milky Way. Researchers suggest the image may not accurately represent its appearance, proposing a more elongated accretion disc instead of the ring-like structure previously released by the Event Horizon Telescope.

*Methane in Titan's Crust

Data from NASA's Cassini spacecraft indicates that Saturn's moon Titan may have a methane-rich crust up to 10 kilometres thick. This insulating layer could explain Titan's shallow impact craters and its methane-rich atmosphere, providing insights into its unique geological and atmospheric dynamics.

*Updates on Earth's Ozone Hole

NASA reports that the annual ozone hole over Antarctica was smaller this year, ranking as the seventh smallest since recovery efforts began. The ozone layer is on track to fully recover by 2066, thanks to international agreements curbing ozone-depleting chemicals.

The Science Report

Antarctic ice core samples suggest Earth has already surpassed a 1.5°C global temperature rise due to human-induced climate change. A study links outdoor lighting at night to increased Alzheimer's risk for those under 65. LED lights on surfboards could reduce shark attacks by mimicking natural camouflage. Nord's latest survey reveals continued use of weak passwords, with "123456" and "password" among the most common.

SpaceTime Series 27 Episode 139

*Gilmore Space Cleared for Orbital Launch

The Australian Space Agency has granted Gilmore Space the final approval needed to conduct its maiden orbital test flight of the Ares rocket from the Bowen Spaceport in North Queensland. This launch will mark the first orbital test flight of an Australian-made rocket from Australian soil, showcasing a new hybrid propulsion system developed by the company.

*Discovery of Red Monster Galaxies in the Early Universe

Astronomers have identified three ultra-massive galaxies, each nearly the size of the Milky Way, that reached their colossal size within the first billion years of the universe's existence. These findings, reported in Nature, challenge existing models of galaxy formation and suggest a more efficient star formation process in the early universe.

*Signs of an Ancient Martian Ocean

China's Mars rover, Zhurong, may have found evidence supporting the theory that Mars' northern hemisphere was once covered by a vast ocean. The terrain around Zhurong's landing site includes features that could indicate past water or ice activity, suggesting a Martian ocean existed billions of years ago.

The Science Robert

Archaeologists in Israel have uncovered 12,000-year-old pebbles that may be precursors to the wheel, potentially pivotal in the evolution of rotating technologies. Meanwhile, the COP 29 climate summit highlights the ongoing rise in fossil emissions, with China remaining the largest polluter. Additionally, a study finds that frequent snoring in tweens is linked to behavioural issues, and a lack of conceptual clarity may explain beliefs in the paranormal.
