Formation of Stars and Planets

The video explores the impact of a meteor 50,000 years ago, forming Arizona's Barringer Crater. A fragment, the Canyon Diablo meteorite, is displayed at the National Museum of Natural History, dating back 4.5 billion years. The video explains how elements like iron, oxygen, and carbon are formed in stars, which collapse under gravity, leading to explosions that create these elements. The formation of the solar system is described, with dust and materials clumping to form comets, asteroids, and planets.
