Tiny little Mars passes brighter Venus low in the sunset this week. Bright Jupiter shines highest at dusk, offering occasional views of its Great Red Spot as it turns — and, for some observers, a double satellite shadow transit by its satellites.
Saturn and Mars pair up low in the west during twilight, with Regulus looking on. Watch their configurations change from day to day. Meanwhile, on the other side of the sky, Jupiter shines low in the southeast during twilight and climbs higher as the night grows late.
Mars, Regulus, and Saturn are lining up in the western sky as they sink lower in the dusk. Jupiter now rises at the end of twilight, far outshining the Sagittarius Teapot to its right. And on Monday night, the Moon closely pairs up with Antares.
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?
