New dark spot on Uranus
As Uranus approached its equinox on December 7, 2007, the planet's storm activity was heating up. Each day exposed more of its northern hemisphere to sunlight for the first time in decades. The Hubble Space Telescope targeted Uranus on August 24, 2006, capturing this view of new dark spots in the northern hemisphere.
