The Constellations
by William Cullen Bryant

O constellations of the early night,
That sparkled brighter as the twilight died,
And made the darkness glorious! I have seen
Your rays grow dim upon the horizon's edge,
And sink behind the mountains. I have seen
The great Orion, with his jewelled belt,
That large-limbed warrior of the skies, go down
Into the gloom. Beside him sank a crowd
Of shining ones. I look in vain to find
The group of sister-stars, which mothers love
To show their wondering babes, the gentle Seven.
Along the desert space mine eyes in vain
Seek the resplendent cressets which the Twins
Uplifted in their ever-youthful hands...

Can you find Saturn's rings in this picture?  This is a view from the Cassini spacecraft currently orbiting Saturn.  Why does one half look blue?
