This ultraviolet picture was taken in 1972 with a camera operated by Apollo 16 astronauts on the Moon. The most common molecules within Earth's exosphere are those of the lightest atmospheric gases. Hydrogen is present throughout the exosphere, with some helium, carbon dioxide, and atomic oxygen near its base.
The Earth and its hydrogen envelope, or geocorona, as seen from the Moon. This ultraviolet picture was taken in 1972 with a camera operated by Apollo 16 astronauts on the Moon. The geocorona is the luminous part of the outermost region of the Earth's atmosphere, the exosphere.
The exosphere is the outermost layer of Earth's atmosphere (though it is so tenuous that some scientists consider it to be part of interplanetary space rather than part of the atmosphere). It extends from the thermopause (also known as the "exobase") at the top of the thermosphere to a poorly defined boundary with the solar wind and ...

Five distinct layers have been identified, the troposphere, stratosphere, mesosphere, thermosphere and exosphere. With solid data, scientists can better understand the extremely complex systems ...
Earth's atmosphere photographed from the International Space Station.The orange and green line of airglow is at roughly the altitude of the Kármán line. [1]The Kármán line (or von Kármán line / v ɒ n ˈ k ɑːr m ɑː n /) [2] is a conventional definition of the edge of space, though it is not universally accepted.
The largest LED screen on Earth, the Exosphere consists of approximately 1.2 million LED pucks that each contain 48 individual LED diodes. Each diode is capable of displaying more than 1 billion ...
