Friday, February 23 • First-quarter Moon (exact at 3:09 a.m. on this date EST). For North America this evening, the Moon shines left or upper left of Aldebaran, and farther upper right of Orion, as shown here. The Moon occults Aldebaran in daylight or twilight for northern and western Europe, and in darkness for…
Now the waxing crescent Moon is easier to see in the west-southwest after sunset. Its curved side points the way down toward Venus.
Sirius the Dog Star blazes in the southeast after dinnertime, the brightest star of Canis Major. Orion stands high to its upper right.
The Winter Hexagon fills the sky toward the east and south these evenings. Start with brilliant Sirius at its bottom. Going clockwise from there, march up through Procyon, Pollux and Castor, Menkalinan and Capella on high, down to Aldebaran, then to Rigel in Orion's foot, and back to Sirius.
The Moon, two days past first quarter, shines to the right of Aldebaran and lower left of the Pleiades. The Great Square of Pegasus is sinking in the west.
Sirius twinkles brightly below Orion in the southeast. Around 8 p.m. Sirius shines straight below Betelgeuse in Orion's shoulder.
Friday, January 12 • Sirius, the Dog Star, rises in the east-southeast around the end of twilight now, if you're near latitude 40° north (New York, Denver, Madrid, Athens). From such latitudes, Procyon — left of Sirius, by 2½ fists at arm's length — precedes it up; "Procyon" is from the ancient Greek for "before…
Orion strides up the southeastern sky after nightfall in January. Above it glitters Aldebaran. Above Aldebaran are the Pleiades. Far left of them shines Capella.
In the evening sky tonight, look lower left of the waxing gibbous Moon for Aldebaran, and upper left of the Moon for the Pleiades.
Maybe you just got a shiny new telescope to call your own. Congratulations — you could be on your way to discovering many amazing, far, deep things in the night sky. Although most of them are so far and faint that just locating and detecting them is the challenge! Whether your new scope is a…
Sirius, the Dog Star, sparkles low in the east-southeast after dinnertime. Procyon, the Little Dog Star, shines in the east to Sirius's left.
As the Summer Triangle sinks in the west, Altair is the first of its stars to go. Start by spotting bright Vega in the northwest at nightfall. The brightest star above it is Deneb. Altair is farther to Vega's lower left.
Astronomy is an outdoor nature hobby. For an easy constellation guide to the evening sky, use the map in the center of Sky & Telescope magazine.
Now that the Pleiades and Aldebaran are up in due east, can Orion be far behind? Orion's entire iconic figure, formed by its brightest seven stars, takes about an hour and a quarter to cross the horizon below them.
When Fomalhaut is due south, you'll always find the first stars of Orion beginning to rise in the east, and the Pointers of the Big Dipper due north below Polaris.
As twilight fades, look low in the southwest for Saturn and Mercury.
Vega is the brightest star in the west in early evening. Its little constellation Lyra extends to the left. Somewhat farther left is 3rd-magnitude Albireo, the beak of Cygnus.
The full Moon of November always rides very high in the middle of the night, almost as high as the full Moon of December.
The Moon occults two 1st-magnitude stars for much of North America just six days apart. The first event happens mostly in early-evening darkness, the second in broad daylight — an extra challenge for the adventurous.
Saturn, in southern Ophiuchus, glows low in the southwest at dusk this week. It's the only bright planet in evening view.
Look northeast in the starry sky these evenings. Capella shines low and brightest. Upper right of Capella, and upper left of the Pleiades, the stars of Perseus stand astride the Milky Way.

R Aquarii may look like a normal pulsing red giant — but it has a lot more going on around it. Its next episode of weirdness may begin soon...
