Today’s Astronomical Events – August 18th, 2015

Tonight presents a good opportunity to see Earthshine on the waxing crescent Moon. Earthshine happens when light is reflected back from Earth’s sunlit surface onto the darkened face of the Moon, thereby allowing the whole of the Moon to be visible. It can easily be seen with just your eyes, but it also makes for a very nice sight in binoculars or through a small telescope with low magnification.

Australian observers get an added bonus. While the Moon hangs high above the western horizon, Mercury should also be visible in the darkening twilight sky. Look for it directly below the Moon and just above the horizon after sunset.
