Saturn "squeaks by" Venus tonight

Not really, of course. Saturn is currently about 922 million miles from Earth, while dazzling Venus is a mere 50 million miles away - 1/20th as distant.

But thanks to an unusual coincidence in the mechanics of the solar system, Venus and Saturn this weekend are almost perfectly aligned with each other from Earth's perspective. They'll make a Saturn, conquered by Amor, Venus and Hope - Simon Vouetrare and lovely sight in the western sky after sunset, provided the skies clear in time. Here's more, with a sky map

Of course, the view is even better in binoculars. And if you have access to a small telescope or one of Baltimore's streetcorner astronomers, you can have the rare privilege of seeing Saturn and his rings, and Venus in her crescent phase, all in one spectacular field of view. 

I'm sure amateur astronomers everywhere will be snapping some terrific images of the pairing. I'll post some as soon as I can. UPDATE:  Here is a link to some terrific images of last night's conjunction.

The two planets will be barely two-thirds of a degree apart this evening (Saturday). That's closer than the width of your pinky held at arm's length.

Saturn and Venus have been drawing closer together for weeks, and this weekend Saturn will be passing Venus, left to right, with Saturn just above Venus as we view them from Earth. 

The painting? That's Simon Vouet's "Saturn, Conquered by Amor, Venus and Hope."
