In the western evening sky, Mars, Pollux, and Castor form up into a straight line and then start curving again. Higher in the southwest, Saturn and Regulus are paired their closest. And on May 4th and 5th, you can try to catch rare opposing crescent moons.
The bright Mars-Pollux-Castor triangle, high in the west, is now flattening out to be more of a curved line than a triangle. Watch it change shape daily. High in the south, Saturn and Regulus are now paired their closest. And Jupiter shines before dawn.
The eyecatcher of the evening sky is the Saturn-Regulus pair high in the south. Or maybe you'd give that award to the Mars-Pollux-Castor triangle high in the west. And using both of these bright sights, do you know how to find the Head of Hydra?
Have you compared the colors of Mars and Betelgeuse? They're one above the other just now. Meanwhile Saturn shines with Regulus in an eye-catching pair, and Jupiter and the waning Moon light the dawn. Also, don't miss out on this week's Space Station flyovers.
The Big Dipper now dumps into the Little Dipper in the north after dark. Saturn and Regulus shine ever higher and closer together in the southeast to south. And with spring now here, trace out the starry constellation patterns of the pipe-smoking Herdsman and the grain-sowing Maiden.
Saturn is at opposition; see if you can observe the Seeliger effect on its rings. Algol-eclipse week comes around again for North America. This is the best time of year for seeing the zodiacal light. And Venus pairs up with Mercury low in the dawn. So get outdoors!
Orion and Sirius shine their highest in the south during evening. High above them Mars still glares brightly, but it's retreating into the interplanetary distance. Low in the dawn, bright Venus and Jupiter remain strikingly close together.
The evening sky turns dark and moonless again, so check in on Comet Holmes high overhead after dark. The comet is spreading out wider every week. And try some deep-sky hunting with binoculars while you're at it. Low in the dawn, watch Venus and Jupiter closing in on each other every day.
