The winter stars set in the southwestern sky in the mid-evening hours of late winter as seen from Northern Virginia. Here you see the stars of the constellations Canis Major, Monoceros, Orion, and Taurus, among others, as well as the Pleiades star cluster. Outreach events such as these are superb opportunities for newcomers to stargazing to learn and gain inspiration. And they help experienced stargazers hone their craft and reconnect with their passion with for the night sky.

More than most planets, Mars has captured the public imagination as a place of mystery, a target of exploration, and possibly the only other place in the solar system that may have once harbored life. The planet figured prominently in science fiction, from the early tales of E.R. Burroughs and H.G. Wells to the latest work of Andy Weir. And Mars is now on the radar of hands-on visionaries like Elon Musk who plan to colonize the planet in the coming decades. The popular fascination with Mars began more than a century ago in the fertile imagination of Percival Lowell, a wealthy and intellectually restless astronomer who speculated about intelligent life on Mars and left a lasting legacy for astronomy.

The last Sunday of northern winter in 2018 brought a clear and dry night for stargazing in the Washington, D.C. area. In this image, taken from The Plains, Virginia, shows a slender crescent Moon just 3% illuminated by the Sun’s light. The Moon is joined by the two inner planets Venus (brighter, at center) and Mercury (upper right). Mercury has just passed its greatest eastern elongation and will now begin quickly moving back toward the Sun. Venus moves in the opposite direction, more languorously, as it slowly gets higher and brighter in the coming weeks.
