SpaceTime Series 27 Episode 30
*Unveiling the Mysteries of Dark Matter with Hypothetical Axion Stars
Could the enigmatic axion star hold the key to understanding dark matter? Join us as we delve into the realm of theoretical physics, where scientists are using the expected properties of these never-before-seen stars to potentially pinpoint the elusive components of dark matter. First proposed in 1977, axions are lightweight candidates for dark matter, and their discovery could illuminate both dark energy and the darkest secrets of the cosmos.
*Mars: A Barren Aquifer and the Quest for Ancient Groundwater
Mars' past as a wet world is etched into its surface, but a new study reveals that ancient Martian aquifers may have been surprisingly dry. Despite evidence of past water flow, researchers suggest that the red planet's southern highlands experienced minimal groundwater recharge. The implications? A vastly different water cycle from Earth's, challenging our search for life and resources on our neighboring world.
*The Cosmic Kitchen: Frying Food in Zero-G
Ever wondered if you could whip up a batch of crispy fries in space? We explore the physics of frying food in microgravity, where bubbles don't rise and steam behaves unexpectedly. Discover how scientists are reimagining cooking techniques for the final frontier, ensuring astronauts won't have to give up their comfort foods on long-duration missions.
*March Skywatch: Equinoxes, Constellations, and Celebrating Pi Day
March heralds the equinox, bringing nearly equal day and night, and setting the celestial stage for stargazing. We'll guide you through constellations like Taurus, Leo, and the river Eridanus, and remind you to mark your calendars for Pi Day. Plus, don't miss the planetary dance before dawn, as Mars, Venus, and Saturn put on a celestial show.
