Early risers can easily spot Mars, Jupiter, and Saturn in the predawn sky. They're three bright beacons above the southeastern horizon. But their arrangement changes over the next few weeks. To figure out which one is which, listen to this month's Sky Tour!
Betelgeuse is starting to recover. After bottoming out at magnitude +1.6 during mid-February, Orion's Betelgeuse had brightened a trace to about magnitude +1.47 as of February 26th. Can you detect any difference by eye yet, using Orion's other shoulder star, Bellatrix, as a comparison? See The Fall and Rise of Betelgeuse.

Meanwhile, Venus, is the dramatically bright "Evening Star" high in the southwestern sky after sunset. It's not a star, of course, but Venus looks so bright because lots of sunlight is reflecting off the planet's nearly pure-white cloudtops.
Looking south after sunset, you'll spot Sirius — the brightest actual star in the nighttime sky. It's only 8½ light-years away. Maybe you've heard Sirius called the Dog Star — have you ever wondered how it got that name? (Hint: Listen to this month's Sky Tour for the answer!)
If your sky is especially dark and free of light pollution, or if you can get to someplace where it is, you can also look for a treat called the zodiacal light. This is a diffuse cone or wedge of soft light that tapers to a point as it extends upward and to the left from the western horizon after twilight ends. Late March is a good time to look because the cone of light stands most upright and there’s no interference from moonlight.
Betelgeuse is rebrightening. After bottoming out at about V magnitude +1.64 in early to mid-February, Orion's Betelgeuse was up to +1.1 as of March 19th. The change from its minimum is obvious to the eye.
Venus remains the bright highlight of the western evening sky. Once night has fully fallen, look for Aries and dimmer Triangulum some 12° to 16° from Venus as shown here. Above Venus, less far above every day, are the Pleiades (out of the frame).

Today marks the 365th anniversary of Christiaan Huygens’ discovery of Saturn’s largest moon, Titan. To this day, Titan is the only solar system moon that humanity has sent a robotic probe to explore.
Saturn creeps upward in the sky before sunrise, when it will become lost in the rays of our bright home star. Before the sky begins to brighten, turn your telescope to the ringed world and try to spot the brightest moon sitting about 6" northwest of the planet, standing alone while most of the smaller, fainter moons cluster closer to the rings.

The 26th offers planetary observers a veritable feast of sights. Early risers are rewarded with a planetary trio in the southeast an hour before sunrise: There, ruddy Mars sits midway between Jupiter and Saturn. The configuration is the closest these three worlds have come in the sky in two decades.
