Venus and Jupiter (and the Crescent Moon)
June brings good news and bad news. First, the bad news: June 2015 is already the third rainiest month in Chicago history (as measured at Midway Airport). The good news: Whenever the skies clear, June 2015 presents a great opportunity to view Venus and Jupiter at sunset all month. Watch this video from Science at NASA:
Of note, on the evenings of June 19 and 20 (this Friday and Saturday), the crescent Moon will be positioned just below Venus and Jupiter. It should be a beautiful sight.
