Mars probe finds super-active auroras and mystery dust clouds
As much as humanity knows about Mars, the planet is still chock-full of surprises. Just ask NASA: University of Colorado researchers using its MAVEN probe have discovered phenomena in the Martian skies that you would never see on Earth. For one, there are auroras that are so energetic (their electrons are 100 times more powerful than a spark of house current) that they plunge far deeper into the atmosphere than back home, or even other places on Mars. Scientists suspect that the Sun is to blame -- Mars doesn't have a protective magnetic field like Earth does, so the solar wind sometimes hits with full force.
