Saturn's Rings in Blue
Written by Fraser Cain
I thought I'd highlight this recent Cassini image of Saturn, it's just so cool looking. What you're seeing is a view of Saturn from high above the planet's northern latitudes, providing nearly a full view of the main rings, from the C ring to the A ring.
Why are the rings blue? Cassini captured this image in three different wavelengths of infrared light, and then they were matched on computer to the colours red, green and blue. So, this isn't what you'd see with your eyes, but it helps reveal subtle differences on the planet and its rings.
The image was captured on April 5, 2007 when Cassini was approximately 1.4 million kilometers (900,000 miles) from Saturn.
