The thermosphere is the layer of Earth's atmosphere located between the mesosphere and exosphere, extending from about 80 kilometers to 550 kilometers above the Earth's surface. It is characterized by very high temperatures, reaching up to 2,500 degrees Celsius or more, due to the absorption of solar radiation by gases like oxygen and nitrogen. The thermosphere plays a crucial role in the Earth's atmospheric processes, including the ionization of gases that allows for the reflection and transmission of radio waves for communication purposes. It is also the region where the International Space Station orbits and where auroras occur due to interactions with energetic particles from the sun. Researchers study the thermosphere to better understand its dynamics, interactions with the sun, and its impact on communication and satellite technologies. This research helps improve our understanding of Earth's atmosphere and how it responds to external influences, such as solar activity.
