Cosmic Supernova Secrets, IO’s Volcanic Heartbeat, and New Glenn’s Vertical Ascent: S27E147

SpaceTime Series 27 Episode 147

* A Cosmic Glimpse into the Universe's Past

Astronomers have witnessed a rare supernova, 2023 UFX, offering insights into the early universe. This unusual stellar explosion involved a metal-poor red supergiant star, providing clues about the cosmic conditions when the universe began. The study, led by Michael Tucker from Ohio State University, reveals how early supernovae seeded the next generation of stars, shaping galaxies like the Milky Way. The findings underscore the significance of dwarf galaxies as analogues for the universe's infancy, highlighting how metal-poor environments influenced star evolution and supernova behaviour.

*Volcanic Mysteries on Jupiter's Moon Io

A new study reveals that Io, Jupiter's volcanic moon, has active volcanoes at its poles, potentially regulating internal tidal heating. This discovery, based on NASA's Juno spacecraft data, sheds light on Io's intense volcanic activity and its role in planetary formation processes. Tidal heating, caused by gravitational interactions, plays a crucial role in sustaining subsurface oceans on other moons, offering a glimpse into the dynamic geological processes shaping celestial bodies.

*America's Next Mega Rocket: New Glenn

Blue Origin's New Glenn rocket has been positioned vertically on its launch pad, preparing for its maiden flight. This 98-metre-tall launch vehicle is set to join the ranks of NASA's SLS Orion and SpaceX's Starship in advancing Space exploration capabilities. The upcoming hot fire test will evaluate the rocket and launch pad systems, paving the way for future missions. New Glenn aims to lift significant payloads into various orbits, with plans for reusability akin to SpaceX's Falcon 9.00:00 This is space Time Series 27 episode 147 for broadcast on 6th December 2024
