The best of space and sky, APOD

Cap Cloud over the Sierra Nevadas – today’s Astronomy Picture of the Day (APOD) is by Guido Montanes, one of the many professional photographers whose work is posted on APOD.  You’ll find a brief explanation of this unusual cloud phenomenon in the photo’s caption.

If you’re interested in astronomy, or just in fantastic images of space, stars, planets, galaxies, clouds – anything you might see by looking up – check out NASA’s APOD Archive.  It’s a wonderful way to take a break, stretch your imagination, and be somewhere else.
