After waiting years for the sun to illuminate Saturn's north pole again, cameras aboard NASA's Cassini spacecraft have captured the most detailed images yet of the intriguing hexagon shape crowning the planet.The last visible-light images of the entire hexagon were captured by NASA's Voyager spacecraft nearly 30 years ago, the last time spring began on Saturn.It encircles Saturn at about 77 degrees north latitude and has been estimated to have a diameter wider than two Earths. The jet stream is believed to whip along the hexagon at around 100 meters per second (220 miles per hour).

Of course scietists are curious as to how and why the hexagon appears. The plan on doing more research to discover the answers to all thier questions. They have been studying images of the hexagon for years. They have also discovered a dark spot within the hexagon that changes its position everytime they look at it. Currently it is at thr two-oclock postion. Now that they can see sharper images of the hexagon, instead of just blobs of it, scientists know that they will have the answers to their questions sooner rather than later.
