Exploring the Solar System and Beyond: Hubble's Discoveries and the Search for Life

The video discusses the discovery of distant objects in the solar system, such as Sedna, using the Hubble Space Telescope. It highlights the methods used to detect extrasolar planets, including observing star wobbles and analyzing atmospheric chemistry for signs of life. The video concludes with the challenges facing the Hubble, as NASA decides against a repair mission.
