Today’s Astronomical Events – April 30th, 2015

Mercury has moved into the early evening twilight and may be glimpsed close to the horizon over the next few nights. Today it passes close to M45, the Pleiades open star cluster, but the faint stars of the cluster itself may be difficult to see without binoculars. (Both the planet and the cluster should easily fit within the same field of view.) Unfortunately, for those in Australia, the cluster may not be visible at all.

Meanwhile, Venus remains a brilliant object nearby and is visible for hours after sunset.
