Mars Life Search to Go in High Gear

The Night Sky· Monday, April 16 · As twilight fades, Look for bright Sirius in the southwest, Orion's horizontal Belt off to the right (with Betelgeuse above it, Rigel below it), and Aldebaran and Venus farther to the right in the west.

Tuesday, April 17 · The eclipsing variable star Algol is at minimum brightness, magnitude 3.4 instead of its usual 2.1, for a couple hours centered on 10:44 p.m. EDT (9:44 p.m. CDT). This is the last chance till August to see Algol at minimum from the latitudes of the U.S.

Wednesday, April 18 · This is the time of year when the dim Little Dipper juts to the right from Polaris (its handle-end) at nightfall. The much brighter Big Dipper curls over high above it, "dumping water" straight down into it.

Thursday, April 19 · Bright Vega is now visible low in the northeast as early as 9:30 or 10 p.m. (depending on where you live). Bright Arcturus dominates the high sky due east. Look a third of the way from Arcturus to Vega for dim Corona Borealis, the Northern Crown, with its one modestly bright star, Alphecca. Look two-thirds of the way from Arcturus to Vega for the dimmer Keystone of Hercules.

Friday, April 20 · Capella, Venus, and Aldebaran form an almost perfectly straight line in the western sky this evening and Saturday evening, in that order from upper right to lower left.
