Two weeks ago, we published a photo by Paul Smith of an awesome red sprite over Oklahoma. Red sprites are a type of transient luminous event (TLE), different from the more familiar lightning that takes place in the troposphere, or lowest part of Earth’s atmosphere. A related phenomena are the blue jets, which pulse from the tops of intense thunderstorms and reach up toward the edge of space. In 2015, European Space Agency (ESA) astronaut Andreas Mogensen photograped blue jets from the International Space Station. A subsequent analysis of the video footage by researchers at Denmark’s National Space Institute – published in early 2017 – revealed some amazing results!
