Researchers at MIT found that greenhouse gases are causing Earth’s upper atmosphere to shrink. Gradually, this will lead to ...

The Thermosphere extends from about 90 km to 500 km above Earth’s surface. While conditions in the thermosphere are hellish, it’s not a hard vacuum. NASA describes it as home to “very low de ...

Thanks to these studies, we now know the five layers of the atmosphere are the troposphere, stratosphere, mesosphere, thermosphere and exosphere (see graphic). Together, these layers protect us ...

The experiment's outcome could upend a long-held theory about the aurora's interaction with the thermosphere. It may also improve space weather forecasting, critical as the world becomes ...
