It also told me that the thermosphere is the hottest layer of the atmosphere.
The layer of gas - called the thermosphere - is now rebounding again.
The fact that the layer in the upper atmosphere known as the thermosphere is shrunken and less dense means that satellites can more easily maintain their orbits.
During that period the atmospheric layer called the thermosphere - from 55 miles to 300 miles above the Earth - cooled and shrank.
The thermosphere is the layer of the atmosphere above the mesosphere.
Above the earth were the layers of the atmosphere—troposphere, stratosphere, mesosphere, thermosphere—and above those was the void of space.
Free moving particles in the thermosphere are preventing our departure from Los Angeles.
Consequently, measuring the temperature of thermosphere with a thermometer is a very difficult process.
In the thermosphere, our thermometer would lose more heat energy from radiative emission then what it would gain from making occasional contact with extremely hot gas molecules.
The last atmospheric layer has an altitude greater than 80 kilometers and is called the thermosphere.
