Message in a bottle rocket
An aurora, high above the northern part of Saturn, moves from the night side to the day side of the planet recorded for the first time ever by Cassini.
These observations, taken over four days, represent the first visible-light video of Saturn's auroras. They show tall auroral curtains, rapidly changing over time when viewed at the limb, or edge, of the planet's northern hemisphere. The sequence of images also reveals that Saturn's auroral curtains, the sheet-like formations of light-emitting atmospheric molecules, stretch up along Saturn's magnetic field and reach heights of more than 1,200 kilometers (750 miles) above the planet's limb. These are the tallest known "northern lights" in the solar system.

If your computer doesn't do Quicktime, watch it here at the source. It's actually bigger and better there.
These are the days of miracles and wonder, this is a long distance call (Paul Simon)
Enjoy your gratitude. I'm immersed in mine. Among my blessings, I give thanks for you.
Mainer, New Yawka, Beijinger, Californian, points between. News, views and ballyhoos that piqued my interest and caused me to sigh, cry, chuckle, groan or throw something.
