Saturn's Rings Continue to Surprise Scientists

If you try to apply simple common sense to how Saturn's rings really work you're going to be sorely mistaken: the giant planet's signature features run circles around average┬Earthly intuition. This has been the case for centuries and is especially true now after recent news from Cassini that the most opaque sections of rings aren't necessarily the densest; with Saturn looks literally are deceiving. While rings are features shared by all of the gas and ice giant planets in our Solar System, Satu

Saturn in Methane

When viewed through a methane filter the banding on Saturn really stands out. The Cassini caption: The soft, bright-and-dark bands displayed by Saturn in this view from NASA's Cassini spacecraft are the signature of methane in the planet's atmosphere. This image was taken in wavelengths of light that are absorbed by methane on Saturn. Dark […]

Rings!

This is a raw image from Cassini. ┬The bright white specks you see are artifact that can be eliminated with processing. This reminds me of a record album. A what? If you don't know what that is ask your Grand Parents. Image Credit: NASA/JPL-Caltech/Space Science Institute

Here's the Cassini description: This half-lit view of Enceladus bears a […]

Tethys and Janus

Click the image for a much larger version. From Cassini: Janus and Tethys demonstrate the main difference between small moons and large ones. It's all about the moon's shape. Moons like Tethys (660 miles or 1,062 kilometers across) are large enough that their own gravity is sufficient to overcome the material strength of the substances […]

Saturn

Here's a new image from Cassini, before we get to the caption you can see a nice planet grouping while you are looking for comet Catalina: Venus, Saturn, and Mars are nicely aligned in the morning sky in the coming days. ┬Go outside before sunrise and look roughly south east and you will see them.
