Today’s Astronomical Events – May 10th, 2015

Libra, the faintest constellation in the zodiac, is at its best visibility for the year tonight. Not only is it faint, it’s pretty barren too, with very few deep sky objects or double stars for amateur astronomers. However, if you’re up for the challenge, look for a skewed trapezoid of four stars between Virgo and Scorpius.
