Episode notes
Asteroid Impact Probability Fluctuation
- Asteroid 2024 YR4's probability of hitting Earth in 2032 briefly rose to over 3%, the highest ever for its size.
- However, it decreased to 1.5%, consistent with scientific predictions.
Black Hole's Constant Light Show
- The black hole at the Milky Way's center, Sagittarius A*, emits near-constant flares of light.
- This suggests the black hole's accretion disk is constantly active with varying levels of eruption.
First Disabled Astronaut Candidate Cleared for ISS
- John McFall, a Paralympic medalist and amputee, is the first physically disabled astronaut candidate cleared for the ISS.
- The ESA confirmed McFall's eligibility after an extensive feasibility study.
