Space Weather

Weather is not limited to planetary bodies. Like all stars, the sun's corona is constantly being lost to space, creating what is essentially a very thin atmosphere throughout the Solar System. The movement of mass ejected from the Sun is known as the solar wind. Inconsistencies in this wind and larger events on the surface of the star, such as coronal mass ejections, form a system that has features analogous to conventional weather systems (such as pressure and wind) and is generally known as space weather. Coronal mass ejections have been tracked as far out in the solar system as Saturn. The activity of this system can affect planetary atmospheres and occasionally surfaces. The interaction of the solar wind with the terrestrial atmosphere can produce spectacular aurorae, and can play havoc with electrically sensitive systems such as electricity grids and radio signals.

Famous quotes containing the words weather and/or space:

    To recover a buried treasure without having it disappear miraculously in the process, one must be entitled to it, and also be willing—really willing deep in his heart—to share it with the poor and helpless. Buried money, especially silver, gives off a bright glow which comes right up through the earth and can be seen as a dim light on nights when the weather is misty or there is a gentle rain.
    —Administration in the State of Ariz, U.S. public relief program (1935-1943)

    The secret ones around a stone
    Their lips withdrawn in meet surprise
    Lie still, being naught but bone
    With naught but space within their eyes....
    Allen Tate (1899–1979)
