Looking high in the southwest at 8:45 PM, the Moon is just one day before its First Quarter as it emerges from the twilight. As twilight ends near 9:15, Leo’s brightest star, Regulus, appears below the Moon, marking the front shoulder or “heart” of Leo, the Lion. The pair won’t set in the west until well after midnight.

The Memorial Day weekend serves as an unofficial kick-off to summer, and the stars are doing their part. One of summer’s quintessential constellations is Scorpio, the Scorpion. The star Antares, regarded as the heart of the Scorpion, is rising in the twilight, and is due south at 1:00 AM EDT.

One of the summer’s brightest stars, Antares, crests due south near 1 o’clock, marking the “heart” of the Scorpion, but also leading the Milky Way back up into the eastern skies. Look to the left of Antares, where the band of faint light belonging to our galaxy, the Milky Way, has reached more that halfway up in the east, highlighted by the stars of the Summer Triangle.
