5. The Night Sky Monday, May 27 This is the time of year when Spica, the brightest star of Virgo, shines due south just after dark. It's far to the lower right of high, bright Arcturus. Its name means "ear of wheat," and the Virgo stick figure is holding it in her hand without paying much attention. To Spica's lower right (by about a fist and a half at arm's length) is the four-star pattern of Corvus the Crow, eyeing it greedily. This year Corvus has Saturn to try to steal too. Saturn is glowing to Spica's left, noticeably brighter. Tuesday, May 28 Jupiter and Venus are now at their closest together, 1° apart low in the west-northwest after sunset. Mercury is above them. Wednesday, May 29 Here it is not even June yet, and the Big Dipper after dusk is already turning around to hang down by its handle. Look for it high in the northwest. Thursday, May 30 Vega is the brightest star in the east-northeast these evenings. The main part of its little constellation, Lyra, hangs from it to its lower right. Friday, May 31 Mercury, Venus, and Jupiter have stretched out into a nice straight line 7° long. Look low in the northwest after sunset. The line will continue to lengthen day by day, as Jupiter descends to the horizon and Mercury pulls a bit higher above Venus. Last- quarter Moon (exact at 2:58 p.m. EDT).
