Although it's being mistakenly promoted as a "rare planetary alignment," one of the best "planet parades" in half a century is now taking place. Here's how to see it.

The best viewing for January's planetary parade is about 90 minutes after sunset, in as dark and clear a spot as you can find. Use binoculars or a telescope for an even better look. The alignment will be visible into February.
