In low Earth orbit there is not enough atmosphere to diffuse & scatter sunlight, so shadows are black & the sky is dark - even when the Sun shines. The aft section of the Space Shuttle Discovery is visible in the background with the Sun hanging over a delicate crescent of the Earth's limb.
A Raging Storm System on Saturn (Dec 26 2011) Image Credit: Cassini Imaging Team, SSI, JPL, ESA, NASA It is one of the largest and longest lived storms ever recorded in our Solar System. First seen late last year, the above cloud formation in the northern hemisphere of Saturn started larger than the Earth and soon spread completely around the planet. The storm has been tracked not only from Earth but from up close by the robotic Cassini spacecraft currently orbiting Saturn.
