Earth's Layers and James Webb Telescope

The video discusses the discovery of a new layer within Earth, located between the crust and mantle, which could enhance understanding of tectonic plate movements. This layer, known as the asthenosphere, is composed of partially melted rocks and plays a crucial role in plate dynamics. The video also covers the James Webb Space Telescope, which is frequently hit by meteorites. Despite the risks, these impacts offer scientists opportunities to study solar system elements and differentiate between frequent and sporadic meteor showers.
