5. The Night Sky Friday, May 18 Arcturus is the brightest star high in the southeast these evenings. It's the leading light of the constellation Bootes, the Herdsman. The main stars of Bootes form a narrow, bent kite shape extending left of Arcturus, nearly three fists at arm's length long. Or maybe the kite is a pointy-toed shoe, with Arcturus the tip of the toe. Saturday, May 19 Venus is moving lower in the west every evening as twilight fades. It's now 2° left of much fainter Beta Tauri, which has been descending almost in parallel with it. Sunday, May 20 Partial/annular eclipse of the Sun! See our article, May 20th's Annular Eclipse of the SunMay 20th's Annular Eclipse of the Sun Arcturus shines high in the southeastern sky after dark. Vega, equally bright, shines lower in the northeast. A third of the way from Arcturus to Vega, look for dim Corona Borealis, the Northern Crown, with its one modestly bright star, Alphecca. Two thirds of the way from Arcturus to Vega is the dim Keystone of Hercules. New Moon (exact at 7:47 p.m. Eastern Daylight Time). Monday, May 21 Can you pick up this month's thin crescent Moon yet? During twilight in the Americas it's barely 24 hours old. (After all, it was in front of the Sun yesterday afternoon!) Using binoculars, look for it no more than a half hour after sunset well below Venus in the west-northwest, as shown at lower right.
