SpaceTime with Stuart Gary SpaceTime

Join us for SpaceTime Series 27 Episode 73, where we delve into the latest cosmic discoveries and advancements shaping our understanding of the universe.
First, astronomers have developed a new theory of dark matter to explain the mysterious dwarf galaxy Crater 2. Despite its proximity at 383,000 light-years from Earth and its large size—making it the fourth largest satellite galaxy orbiting the Milky Way—Crater 2 has a surprisingly low surface brightness and velocity dispersion. This has led scientists to propose the self-interacting dark matter (SIDM) theory, which may better account for the galaxy's unusual properties.
Next, new research dismisses the idea of a lake under the Martian south polar ice cap. Instead, it suggests that the bright radar reflections previously interpreted as liquid water are likely due to resolution interference between radio waves. This finding, based on computer simulations, challenges the notion of subsurface liquid water on Mars.
Finally, we highlight the development of a new daytime optical telescope, the Huntsman, which allows astronomers to observe celestial objects even when the sun is high overhead. This groundbreaking instrument, located at Siding Spring Observatory, uses an array of camera lenses designed for ultra-sensitive night sky observations but can also accurately measure stars and satellites during daylight.

Join us for SpaceTime Series 27 Episode 72, where we uncover the latest cosmic discoveries and scientific advancements.
First, astronomers have discovered that a tiny moonlet orbiting the main belt asteroid Dinkinesh is actually two little moons melded together. Known as contact binaries, these moonlets could provide fresh insights into the complex processes behind planetary formation and evolution. We delve into the details of this fascinating discovery made by NASA's Lucy spacecraft.
Next, we discuss the possibility of an underground ocean on Saturn's moon Mimas. Scientists speculate that as Mimas's orbital eccentricity decreased, its icy shell may have melted and thinned, leading to the formation of a subsurface ocean. This finding could have significant implications for our understanding of the Saturnian system.
Finally, we highlight NASA's launch of its second pre-fire satellite into orbit aboard Rocket Lab's Electron rocket. These satellites are designed to study how much heat the Arctic and Antarctic are radiating out into space and how that's influencing global climates. We explore the mission's objectives and potential impact on climate science.

First, we discuss NASA's announcement that the Hubble Space Telescope will begin winding back its science programme due to ongoing issues with its gyroscopes. This decision marks a significant transition for the historic observatory, which has revolutionised astronomical discovery since its launch in 1990.
Next, we cover the long-awaited launch of Boeing's Starliner, which has finally taken a crew to the International Space Station. This milestone paves the way for Starliner to join SpaceX's Dragon in transporting crews to the orbiting outpost under NASA's commercial crew programme.
Finally, we highlight NASA's OSIRIS Apex spacecraft's survival after a close encounter with the sun. This mission is essential for its upcoming rendezvous with the asteroid Apophis in 2029.
