Summary
The discussion highlights the existential threats posed by asteroids and comets within our solar system, emphasizing the chaotic nature of these celestial bodies and their potential to impact Earth. With billions of comets and asteroids orbiting the sun, the risk of a catastrophic event looms, particularly from near-Earth objects (NEOs) that could be on a collision course with our planet. Currently, over 90% of NEOs larger than one kilometer have been cataloged, yet many smaller, potentially devastating asteroids remain undetected.
The episode delves into the dynamics of the asteroid belt and the influence of Jupiter's gravity, which prevents the formation of a larger planet from these asteroids. It explains how some of these asteroids can be nudged into orbits that cross Earth's path, posing a significant threat. The conversation also touches on the Oort cloud, a distant region believed to harbor long-period comets that could strike Earth with little warning, making them particularly dangerous.
In terms of mitigation strategies, the episode discusses various methods for deflecting asteroids, including kinetic impactors and potential nuclear options, should an imminent threat be detected. The importance of early detection is underscored, as it would provide humanity with more options to avert disaster. The conversation concludes with a reflection on the need for long-term planning to address not only asteroid threats but also pressing issues like climate change, urging a proactive approach to safeguard future generations.

Rubin Observatory just came online and one of its main goals is to detect comets and asteroids that could threaten the Earth. But how long will this take? How many threats do we know of so far? And what could we do about it if we discovered one with our name on it? Join us today as we explore just how dangerous the skies can be...Written & presented by Prof. David Kipping, edited by Jorge Casas.→ Support our research: https://www.coolworldslab.com/support→ Get merch: https://teespring.com/stores/cool-worlds-store→ Check out our podcast: www.youtube.com/@CoolWorldsPodcastTHANK-YOU to T.

Alien megastructures are back in the headlines after some new research published last week. It has been claimed that Tabby's Star is confirmed to be steadily dimming, which is completely unexpected behavior for a star. Prof Kipping explains what we know (and don't know) about this mysterious star and what astronomers really mean by "alien megastructures".::More about this Video::► Montet & Simon (2016), "KIC 8462852 Faded Throughout the Kepler Mission": http://arxiv.org/abs/1608.01316► Schaefer (2016), "KIC 8462852 Faded at an Average Rate of 0.165+-0.013 Magnitudes Per Century From 1890 To 1989": http://arxiv.org/abs/1601.03256► Boyajian et al.
