mesosphere, thermosphere and exosphere (see graphic). Together, these layers protect us from the sun’s harmful radiation and keep temperatures on Earth habitable for all living beings.

Thermosphere: The layer of the Earth's atmosphere above the mesosphere, characterized by high temperatures and the presence of ionized gases. Meteoric metal layers: Layers of metal atoms in the ...

This layer of the atmosphere is notoriously difficult to study, but new research sheds light on its mysterious processes.

Mesosphere: A layer of the Earth's atmosphere located above the stratosphere and below the thermosphere, typically between 50 and 85 kilometers in altitude. Hydroxyl (OH) Airglow: A natural ...

NASA's TES-22 CubeSat launched with tech that speeds up satellite deorbiting to clear space debris. It carries technology to study the thermosphere and test solar activity’s impact on satellite ...

Although they don't impact the surface directly, historical evidence and simulations suggest airbursts can pack a punch.
