Mars shines to the left or lower of the Moon early Saturday evening. On Tuesday, the Moon is in Aquarius - look to its left for Fomalhaut, the Autumn Star.
In twilight Friday evening, Saturn, Venus, and Antares form a nearly vertical, curving line low in the southwest. Watch the configuration change this week.
Saturn and Antares form a compact triangle with Venus, low in the southwest at dusk on Friday. The modest Orionid meteors continue before dawn Saturday.
The full Moon rises around sunset on Saturday. Almost 20° to its left are the brightest stars of Aries. Like the Moon, faint Uranus is also at opposition.
Jupiter and fainter Mercury have a close conjunction on Tuesday morning, October 11th. Look low due east about 45 minutes before your local sunrise time.
A twilight challenge: About half an hour after your local sunset time, look for Venus very low in the west-southwest through the twilight.
The "W" of Cassiopeia stands high in the northeast after dark. In the southwest at dusk, Saturn and Antares continue to pull farther to the right of Mars.
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?
