Atmosphere of Uranus

Views from the Hubble Telescope
Atmosphere of Uranus
Infrared filters allow astronomers to probe in more detail the structure of Uranus's atmosphere, which consists mostly of hydrogen, with traces of methane.  Although the atmosphere's three layers show up as red, yellow, and blue in this image in reality the rings are as dark as black lava or charcoal.

This postcard is postmarked in 2007.
