Embark on a Cosmic Journey with Astronomy Daily S03E171.
The universe is a vast and mysterious place, and Astronomy Daily is here to guide you through its wonders. In this episode, host Anna takes us on an enthralling voyage through the cosmos, covering a range of topics that are sure to ignite your curiosity and wonder.
The episode kicks off with a look at the upcoming Draconid meteor shower, an annual celestial event known for its potential to dazzle skywatchers with breathtaking meteor storms. This year's display promises to be a treat, with the best viewing time right after nightfall on October 7. Anna provides tips on how to maximize your stargazing experience, including finding a dark location away from city lights and being patient as your eyes adjust to the darkness.
Next, we zoom out to the International Space Station (ISS) for an update on crew changes and mission developments. Astronauts Butch Wilmore and Suni Williams are preparing for their return journey aboard the SpaceX Crew Dragon spacecraft, marking a significant transition as they initially arrived via the Boeing Starliner. This crew rotation highlights the ongoing collaboration between NASA and commercial partners in maintaining a continuous human presence in low Earth orbit.
The episode also delves into groundbreaking research on the effects of long-term space travel on the human brain. Recent studies on mice have revealed concerning impacts of galactic cosmic radiation on cognitive abilities, a crucial consideration for future Mars missions. However, there is hope, as the research also suggests potential protective measures through antioxidant and anti-inflammatory drugs.
One of the most exciting segments of the episode is the discussion on the James Webb Space Telescope and its role in solving one of cosmology's biggest puzzles: the Hubble tension. By capturing stunning images of distant supernovae, the telescope is providing new insights into the rate at which the universe is expanding, potentially bridging the gap between conflicting measurements.
Finally, Anna updates listeners on Earth's temporary new mini moon and the ongoing mission of NASA's Curiosity rover on Mars. Despite significant wear and tear on its wheels, Curiosity continues its mission to search for signs of ancient microbial life, showcasing the resilience and ingenuity of NASA engineers.
Whether you're a seasoned astronomer or a curious newcomer to the world of space exploration, this episode of Astronomy Daily offers something for everyone.
