Firey Icy Beauty of an Infrared Neptune


The distant "ice giant" planets Uranus and Neptune look like "fire worlds" in deep space in new photos released Hawaii's Keck Observatory. Caltech astronomer Mike Brown snapped the new pictures in infrared light, using Keck's adaptive optics system.  Brown posted the pictures via Twitter from Sept. 18 to Sept. 20. Two shots show bright streaks on Neptune, which is about 17 times as massive as Earth and orbits 30 times farther from the sun than does Earth.

The image below shows Neptune and its moon Triton (lower right), taken in infrared light also at the Keck Observatory.
