5. The Night Sky Sky & Telescope Friday, April 4  After dark this week, look southeast to spot bright Mars shining above lesser Spica. Mars is at opposition this week! Look far left from them to find Arcturus, the "Spring Star," in the east. Arcturus forms the pointy bottom of the long, narrow kite asterism made by the brightest stars of Bootes. The kite is currently lying on its side to the left of Arcturus, with its head at the far left bent slightly upward. The kite is 23° long: about two fist-widths at arm's length. Saturday, April 5  The Moon passes below Jupiter in Gemini this weekend, as shown at right. Although they look close together, Jupiter is currently almost 2,000 times farther away. And it's 40 times bigger than the Moon. All week look above Jupiter for Pollux and Castor, left of it for Procyon, and farther right of it for Capella. Way down below it is Betelgeuse, the top corner of Orion. Sunday, April 6  First-quarter Moon. It's shining near Jupiter, which by no coincidence was at quadrature (90° east of the Sun) just a few days ago. Monday, April 7  The Moon forms a curving arc this evening with Pollux and Castor to its upper right and Procyon to its lower left. To the right of the arc shines brighter Jupiter. Tuesday, April 8  Mars is at opposition — its closest opposition since December 2007. Mars is actually nearest to Earth on the 14th, but the difference is barely a trace. This is the month for Mars with your telescope!
