Today’s Astronomical Events – May 30th, 2015

Venus passes Pollux, one of the Gemini twins, in the evening twilight tonight while his brother, Castor, continues to shine slightly further to the north. Compare the view to just one week ago and see how far the planet has moved in the intervening time. It’s drawing closer to Jupiter and the planetary pair will be at their closest at the end of next month and the beginning of July.
