From May 22–31, evening skies highlight a first-quarter Moon transitioning to full on May 30, often accompanied by Regulus, Spica, and orange Antares. Constellations like Leo, Boötes, and Cassiopeia are visible, with Vega and Lyra rising in the east and the Summer Triangle forming by May 31. Theta Centauri becomes visible low in the southern sky for northern observers. Venus and Jupiter dominate the western twilight sky, drawing closer each night, while Mercury emerges faintly near sunset. Mars and Saturn appear low in the eastern dawn. Observers can enhance their stargazing with binoculars, star charts, or modern smart telescope technology. https://skyandtelescope.org/astronomy-news/observing-news/this-weeks-sky-at-a-glance-may-22-31/
