The Crescent Moon Greets Saturn with Earthshine

October 16th, 2015

Having turned new on the 13th, the waxing crescent Moon now passes close to Saturn and gives us a glimpse of Earthshine on its darkened surface. Observers in the southern hemisphere should easily see the pair in the early evening twilight but those in the United Kingdom may have difficulty spotting Saturn.

If you’re able to see the Moon but the planet eludes you, use binoculars to scan the sky to the lower right and Saturn might appear against the twilight. Take this opportunity if you can as this will be your last chance to see the Moon and Saturn together in the evening sky until next year.
