Parts of Europe, Africa, and Asia will see a penumbral lunar eclipse Friday. Eclipse or no, look for the Great Square of Pegasus to the Moon's upper left.
First-quarter Moon shines over Mars Friday evening. The triangle of Mars, Saturn, and Antares, continues to lengthen as summer nears its end.
A Friday twilight challenge: Shortly after sunset, use binoculars to look for the super-thin crescent Moon near Jupiter and Venus just above the horizon.
Venus-Jupiter conjunction on Saturday: about 20 minutes after sunset, look above the western horizon, left of where the Sun went down. Bring binoculars.
Summer is on the decline, temperatures notwithstanding: when darkness falls, Cassiopeia has now risen as high in the northeast as the Big Dipper has sunk in the northwest.
This Friday, look lower right of the waxing gibbous Moon for the ever-changing Saturn-Mars-Antares triangle. Full Moon on Wednesday night.
The crescent Moon poses with Jupiter low in the west in twilight Friday. Early next week, Mars passes 0.9° beneath Delta Scorpii, the brightest star in the head of Scorpius.
As summer goes on, Scorpius shifts westward from its high southern stance just after dark; Sagittarius moves in from the east. Prime time for Messier objects!
Starry Scorpius is sometimes called "the Orion of Summer" for its brightness, its blue-giant stars, and its 1st-magnitude red supergiant (Antares).
The Moon shines over Mars, Saturn, and Antares at dusk. And after Saturday's sunset, use binoculars to look for Venus — with fainter Mercury a bit above.
The waxing crescent Moon shines in the west at dusk on Friday. Jupiter is the bright "star" at its upper left (for North America).
Is your sky dark enough to see the Coma Berenices star cluster naked-eye? Spot Jupiter in the west after twilight this week and the cluster just above.
This is the time of year when the two brightest stars of summer, Arcturus and Vega, hang about equally high overhead shortly after dark: Arcturus in the southwest, Vega in the east.
The Moon, Mars, and Saturn make a wide, flattish triangle Friday night. At nightfall, look for the Big Dipper hanging straight down in the northwest.
Friday evening the Moon poses between Jupiter and Regulus. Turn binoculars on Jupiter, and you'll find the star Chi Leonis among the Galilean satellites.
The Mars-Antares-Saturn triangle rises higher at dusk every night, and halfway between Mars and Jupiter stands Spica. Cassiopeia lurks low in the north.
The last-quarter Moon doesn't rise until around 2 a.m. It'll be between the Aquarius's dim spilling bucket and the dim Circlet of Pisces.
The nearly full Moon looms low in the east-southeast at sunset and shines above Mars as twilight fades. How soon can you pick out Mars?
As twilight fades, look upper left of the first-quarter Moon for Regulus. Brighter Jupiter shines much farther to the Moon's left (for North America).
After sunset Saturday, catch the hairline crescent Moon just above the horizon. Bring out your scope to see a double-shadow transit on Jupiter Friday night.
The last-quarter Moon shines above Capricornus before dawn's first light. These evenings, the long, dim sea serpent Hydra snakes across the southern sky.
As night descends, look high in the west for Pollux and Castor - the heads of the almost-upright Gemini twins form the top of the Arch of Spring asterism.
Comet 252P/LINEAR is crossing Ophiuchus very high before the first light of dawn. The Moon Friday evening forms a gently curving row with Regulus and Jupiter.
Looking west in twilight, use the thin crescent Moon as your guidepost to Mercury. And have you tried yet for Comet 252P/LINEAR?
Spring is here! Which means Arcturus shines brightly in the east. The Big Dipper, high in the northeast, points its handle toward it.
