Uranus
When Voyager 2 swung by Uranus in January 1986, it captured a wide-angle view of the ice giant at resolutions reaching 90 miles (140 km). The pale blue-green color of the planet’s thin crescent, a product of atmospheric methane, matched the colors captured by ground-based telescopes on Earth. The NASA probe was around 600,000 miles (1 million km) from Uranus at the time this photo was taken.
