Red planet Mars glows green at night due to chemical reactions

It might be known as the Red Planet, but according to observations from NASA - Mars'glows green' at night due to chemical reactions in its upper atmosphere. The eerie phenomenon was captured by NASA's'MAVEN' orbiter but astronauts are unlikely to see it as it is only visible as ultraviolet light - naked to the human eye. The discovery could help create a more detailed picture of Martian weather - which will help the first crewed missions to Mars expected to leave sometime in the 2030s. The first crewed mission to Mars will need better forecasts than are currently available to avoid wild winds and storms that can last weeks, the authors explained. Each evening the upper atmosphere softly flickers in ultraviolet light as the sun sets and temperatures fall to minus -79.6 degrees Fahrenheit and below.
