Weekly Stargazing Tips

Unless otherwise specified, viewing times are local time regardless of time zone, and are good for the entire Lower 48 states (and, generally, for Alaska and Hawaii). Check out last week's tips if you missed a night.

Crowning the Crown

Corona Borealis, the northern crown, stands half-way up the eastern sky as darkness falls this evening. It is a small semicircle of moderately bright stars that opens to the left. It is crowned by a binary star system known as Alphecca.

Early Beacon

Spica is close to the right of the Moon at nightfall. The brightest star of Virgo shines blue-white, indicating that its surface is thousands of degrees hotter than the Sun’s.

Ophiuchus

Ophiuchus, the serpent bearer, is in good view tonight. The big constellation clears the eastern horizon by about 10 p.m., and arcs high across the south during the night. Most of its stars are relatively faint, so you need a starchart to find them.

Moon in Balance

The gibbous Moon is in “balance” tonight. It is passing through Libra, the balance scales. Libra’s two brightest stars are close above the Moon. The bright planet Saturn is a little farther to the lower left of the Moon, with orange Antares below Saturn.

Moon and Saturn

The planet Saturn is in good view tonight. It looks like a bright golden star close to the upper right of the Moon at nightfall, and it stays near the Moon all night.

Moon and Antares

The full Moon arcs low across the southern sky tonight. It’s accompanied by bright Antares, the heart of the scorpion, and the planet Saturn. Antares is to the right of the Moon as night falls, with Saturn farther to the upper right of the Moon.

Follow the Leader

Look for bright white Procyon low in the west in early evening. The name Procyon means “before the dog.” From most northern latitudes, Procyon rises before the Dog Star, Sirius. When they set, however, Sirius goes first and Procyon follows.
