Going Interstellar with TESS and Kepler

The video explores the concept of space as a series of nested bubbles, starting with Earth's magnetosphere and extending to the heliosphere. It discusses the Voyager spacecraft's journey beyond the heliosphere and the challenges of reaching nearby stars like Alpha Centauri. The Kepler Space Telescope's discovery of exoplanets is highlighted, showing that there are more planets than stars in our galaxy. The video concludes with the TESS mission, which aims to find and study nearby exoplanets, paving the way for future exploration with the James Webb Space Telescope.
