Saturns rings are disappearing and the blue sky of the north pole can be seen

Peculiar things are happening to Saturn, every 15 or so years the planet tilts so that we see the rings edge on. This gives the appearnace of them vanishing, and shows us the unusual blue North Pole.

We are experiencing a "ring plane crossing" with Saturn.

As Saturn goes around the sun, it periodically turns its rings edge-on to Earth—once every 14-to-15 years. Because the rings are so thin, they can actually disappear when viewed through a small telescope.

In the months ahead, Saturn's rings will become thinner and thinner until, on Sept. 4, 2009, they vanish.

It'salso a good time to behold Saturn's curiously blue north pole.

In 2005 the Cassini spacecraft flew over Saturn's northern hemisphere and found the skies there as azure as Earth itself. Saturn is a planet of golden clouds, but for some reason clouds at high northern latitudes have cleared, revealing a dome of surprising blue.

For years, only Cassini has enjoyed this view because from Earth, the blue top of Saturn was hidden behind the rings.

Now that Saturn's rings are only open 8 degrees, we can finally view its northern hemisphere's beautiful teal blue colored belts and zones, which really did look blue through my 10-inch telescope,
reports Dan Petersen of Racine, Wisconsin.

Even with rings diminished, Saturn is still a breathtaking sight through the meanest of telescopes.
