Solar wind power likely governs Uranus' thermosphere temperature. Story by Hayley Dunning • 5d. U ranus's upper atmosphere has been cooling for decades—and now scientists have shown why.

The atmospheric temperature spike, which was caused by successive geomagnetic storms, suggests the "solar maximum" is fast approaching. Earth's thermosphere recently hit a near 20-year temperature ...

FARGO — The thermosphere is a layer high in the atmosphere known for extremely high temperatures, extremely low air density and, on occasion, the Northern Lights. From about 50 miles above the ...

Spacecraft don't melt from thermosphere temperatures. The ramifications of a high temperature, such as 2,000 degrees Celsius, are different at sea level than in the thermosphere, according to Rona ...

The thermosphere is the largest portion of the Earth's atmosphere and is the next-to-last region before you reach the vacuum of outer space. The fact that it has contracted is not surprising; ...

This cooling is in agreement with models based on increasing carbon dioxide levels. Further up in the thermosphere (90-800 km) there have been no direct measurements of temperature. However, a ...

The thermosphere naturally contracts and expands every 11 years in response to the sun’s routine activity cycle, the scientists noted. When that activity is low, ...

Earth's thermosphere is one of the least explored parts of the atmosphere, but it is important because "the thermosphere is where the sun first interacts with our atmosphere," said James Russell ...

The Department of Defense closely monitored NASA's Thermosphere Ionosphere Mesosphere Energetics and Dynamics Mission, or TIMED, craft to see if it collided with the Russian satellite on Feb. 28, ...

The thermosphere extends from the top of the mesosphere, at around 53 miles (85 kilometers) above ground, to the bottom of the exosphere, which begins at around 372 miles (600 km) above the ground ...
