Today’s Astronomical Events – February 22nd, 2015

Having passed Venus and Mars yesterday, the waxing crescent Moon continues its journey east across the sky. It will pass M45, the Pleiades open star cluster, in a few days, but tonight presents a good opportunity to see Earthshine. This happens when light is reflected back from the Earth onto the Moon’s surface, thereby illuminating just enough of the dark unlit portion to make the whole of the Moon visible.
