Quite a chase in the southern sky tonight:
a bright full moon chasing Sagitarius; Sagitarius chasing the Scorpion; Scorpio chasing Saturn.

Ten years ago on a summer afternoon, three little boys and I signed our names on a white sheet of paper and mailed it to the Cassini-Huygens project. They received over 600,000 signatures from around the world. Each signature was scanned and transferred to a DVD that was stored on the Cassini craft before it rocketed into the solar system.

A small part of us and that summer day is orbiting Saturn tonight.

Ooops. Of course it is Jupiter, not Saturn, in the night sky this week. Brain blip. I must have valued alliteration and reminiscing over accuracy--
