The gorgeous streams of light in Earth’s atmosphere known as auroras are not special to our planet, and now astronomers are learning more about the ones on Uranus. <br />NASA’s Goddard Space Flight Center has released an image of auroras flaring on that icy, ringed planet in our outer solar system, a composite made by images from the Voyager 2 space probe and the Hubble Space Telescope that is in orbit around Earth. They look a bit like lightning shocks, stark white against the planet’s blue atmosphere.
