Look to the Skies!

It seems to have been a while since we've had a good planet grouping in the evening sky, but the current show is starting now! While Jupiter and Saturn have been in the evening sky for a few months, they are slowly retreating towards the Sun as the Earth's more rapid motion appears to move them to the far side of the solar system. Meanwhile, Venus has leapt from behind the sun (again, its motion is more rapid than the Earth), and is about to join the other pair in the early evening. Tonight Venus was still well below Jupiter, but tomorrow (Saturday, 23 November) will approach within 1.5 degrees (3 moon-diameters), making a striking sight! Next week, on Thanksgiving night, the crescent moon joins the grouping, and finally on 10 December, Venus passes Saturn and the conjunction show will end for now. Here is how they looked tonight (Friday, 22 November) from near Cornville, AZ. The planets are about to set behind the Mingus Mountains, with the lights of Cottonwood, AZ in the foreground. In the labeled image at right, you can also see the "teapot" asterism of Sagittarius as it also moves behind the sun for the season.

Catch the show while you can!
