Neon Saturn
In this false-color image, the Cassini spacecraft captures Saturn's glow, represented in brilliant shades of electric blue, sapphire and mint green, while the planet's shadow casts a wide net on the rings. The colors represent different wavelengths: red is thermal heat originating within the planet; in blue, icy ring particles shimmer in sunlight scattered through the rings; in green, a thick covering of high-altitude hazes strongly reflect sunlight.
