Jupiter and Mercury at Sunset

Monday, March 14th, 2011

As though to commend Jupiter’s final days in the evening sky, or perhaps to leave us with some little bauble as our largest planet disappears from view, our smallest planet has joined Jupiter on the sunset horizon. On Monday, March 14, you’ll find tiny Mercury glistening to the near lower-right of brighter Jupiter. The following evening, March 15, Mercury will be more apparent as the two planets sparkle side-by-side. By next week, Mercury will humbly adorn the sunset, where Jupiter once reigned supreme.

Jupiter with the Crescent Moon

Sunday, March 6th, 2011

This evening, watch for the very young crescent Moon to pair with Jupiter on your west horizon at sunset.  As the sky darkens, see if you can spot the Moon’s earthshine – that unlit side of the Moon glowing in Earth’s own reflected sunlight.

Jupiter is quickly approaching solar conjunction, which means we’ve only a couple more weeks to catch it in the evening sky. The giant planet slips away with style, however, pairing with tiny Mercury for several nights later this month. Once Jupiter disappears from the night sky, it will spend several weeks passing “behind” the Sun, before reappearing in May’s morning sky.

Crescent Moon with Venus!

Sunday, February 27th, 2011

Luna will rise as a waning crescent Moon paired with bright Venus, this week, offering both a beautiful ending to February and a delightful opening to March. You’ll find the two on your ESE horizon about an hour before sunrise both mornings, with Luna as a 17% crescent above Venus on Monday and as a 10% crescent beneath Venus on Tuesday.

While you’re out, why not grab a pair of binoculars and tour that dusty region to the near right of Venus. There, you’ll find the many celestial wonders of Sagittarius and Scorpius, including M22 and M28, the Lagoon and Trifid Nebulas, and M4 with bright red Antares.

Valentine’s Day – Space Style!

Monday, February 14th, 2011

Space, and our planet, truly are beautiful. This morning, people from all across the world are celebrating Valentine’s Day with beautiful images of nature’s hearts, as seen from Space. I’ve collected a few to share with you. I’ll add more as I find them. Feel free to share any that you find, and I’ll add them to the collection!

Jupiter and Crescent Moon at Sunset

Sunday, February 6th, 2011

Watch for Jupiter with the Crescent Moon above your WSW horizon at sunset, Sunday evening. Less than ten degrees will separate the two, with Jupiter appearing as a bright star to the left of “smiling” Luna. While the two may appear close to each other, nearly 500-million miles spans the distance between them. And though Jupiter appears the smaller of the two, that great gas-giant measures more than 41 times the diameter of the Moon.

Crescent Moon with Venus in a sea of stardust

Friday, January 28th, 2011

This weekend promises a special celestial treat, as the waning crescent Moon pairs with Venus in the early morning sky. Even better, the two will be positioned against the dusty backdrop of the galactic center, just a few degrees from the Lagoon and Trifid Nebulas and the Butterfly and Cat’s Eye clusters. Bright Antares, to the near right, will add a touch of red sparkle to the scene.

While Venus, the Moon, and Antares can be enjoyed without visual aid, you’ll need a pair of binoculars to enjoy the surrounding companions.
