What is the special features in the thermosphere?

The thermosphere is characterized by extremely high temperatures, which can reach up to 2,500 degrees Celsius (4,500 degrees Fahrenheit) or more, due to the absorption of intense solar radiation. This layer of the atmosphere also contains the ionosphere, where solar and cosmic radiation ionizes atmospheric particles, enabling radio wave transmission and the occurrence of auroras. Additionally, the thermosphere extends significantly above the Earth, blending into the exosphere, and experiences very low density, meaning that particles are far apart compared to those in lower atmospheric layers.
