5. The Night Sky Sky & Telescope Friday, April 15 The Moon this evening forms a gently curving row with, to its left, Regulus and then bright Jupiter, as shown at right. Saturday, April 16 Look above the Moon after dusk for Regulus, the bottom of the now-vertical Sickle of Leo. They're separated by about 3° (for the Americas), about two finger-widths at arm's length. Sunday, April 17 That bright "star" close by the Moon this evening is Jupiter. Although they look close together, Jupiter is currently 1,760 times farther away. And it's 40 times larger in diameter. Monday, April 18 This is the time of year when, as twilight fades, the dim Little Dipper extends straight to the right from Polaris in the north. Very high above the end-stars of the Little Dipper's bowl, you'll find the end-stars of the Big Dipper's bowl. Tuesday, April 19 Bright Arcturus is climbing high in the east these evenings. Equally bright Capella is descending high in the northwest. They stand at exactly the same height above your horizon sometime between about 8:30 and 10:00 p.m. daylight-saving time, depending mostly on how far east or west you live in your time zone.
