The moon, Venus, and Jupiter, as promised

February 26, 2012

A followup from a recent post. Here’s how the celestial trio looked from my driveway last night. Venus is lowest and Jupiter is highest. No scope for this shot, just my old Nikon Coolpix 4500 on a tripod, about a 1 second exposure. The CCD is a little noisy at that length, especially in low light, so the picture is more pixellated than I’d like, but it’ll do.

Here’s a closeup of Venus and the moon, shot through my SV-50 and a 32mm Plossl (7x), unzoomed.

Tonight the moon is up by Jupiter, and even closer to the King of Planets than it was to Venus last night. I got a quick naked-eye look as we were off to dinner tonight, but by the time we were done eating, the clouds had rolled in, the moon was just a bright fuzzy spot in the sky, and the planets were completely obscured. So it goes.

Next month Venus will be even higher in the sky and Jupiter will be a little lower, so the two will be even closer and prettier when the moon visits them next. Even when the moon is elsewhere, the two planets reward study with the naked eye, binoculars, and telescopes. Mars is up in the east right after sunset, as close to Earth as it will get for the next couple of years, and Saturn is rising around midnight for the night-owls. It’s a good time to observe the planets. Even if all you have time for is a naked-eye peek, you can still appreciate that these moving lights in the sky–“planet” is Greek for “wanderer”–are worlds, that we know something about them, and that someday–maybe–we’ll go out there and explore them ourselves.
