Exosphere: The Outer Edge of Life

The exosphere is the outermost layer of our planet"s atmosphere, stretching from the edge of our atmosphere to the edge of space. It is a dynamic and complex region, where interactions with space and other celestial bodies shape its composition, temperature, and pressure. The exosphere is where life can exist, albeit in a very different form than on Earth, and it is also where space weather and other celestial phenomena can have a profound impact on life on Earth. Understanding the exosphere and its relationship with life on Earth is crucial for our understanding of our planet and for future space exploration efforts.
