Young Crescent Moon to Journey Past Venus and Jupiter This Week
This week, sky watchers can enjoy a beautiful celestial sequence as a young crescent moon journeys …
The Celestial DisplayKeep an eye on the western sky after sunset this week to watch a beautiful sequence unfold over several evenings. A young crescent moon moves first past Venus and then Jupiter, creating a chance to track the moon's movement through its orbit around the Earth.The Lunar JourneyThe chart shows the view on May 18 looking west from London at 22:00. The moon will be just 2.4 days old, and just 6.2% of its visible surface will be illuminated. Close to this slim arc of light, Venus will be shining brightly, unmistakable even in twilight.Jupiter sits a little higher and dimmer, but is still prominent. Finally, dimmest of all are the stars of Gemini; the twins, Castor and Pollux. Over the next few nights, the moon moves eastward, towards Jupiter, growing in percentage illumination as the angle it makes to the sun changes night after night.Optimal Viewing ConditionsFor the best chance of seeing the alignment, choose a viewpoint with an unobstructed western horizon. The crescent moon and planets will be visible to the naked eye, but binoculars may enhance the viewing experience by revealing more details of the moon's surface and the surrounding stars.A Global PerspectiveFrom the southern hemisphere, the view will be a little easier to see. At this time of the year, the ecliptic, the path followed by the sun, moon and planets, is tilted upwards more steeply from the horizon. This will place the conjunction higher in the sky at sunset, making it more accessible for observers in southern latitudes.
