Last Week's Stargazing Tips

May 27: Vanishing Winter

Some of the bright lights of winter are dropping from the evening sky. Low in the west at nightfall, look for Procyon in Canis Minor, the little dog. And look to its upper right for the twins of Gemini above Venus, the “evening star.”

May 26: Omega Centauri

About 160 known globular clusters orbit the center of the Milky Way galaxy. The biggest and brightest is Omega Centauri, which is low in the south in early evening. It may be the stripped core of a smaller galaxy that the Milky Way took over long ago.

May 25: First-Quarter Moon

The Moon is at first quarter at 12:19 p.m. CDT. At that moment, sunlight illuminates one-half of the lunar hemisphere that faces Earth. The Moon rises in early afternoon and stands high in the southwest at nightfall.

May 24: Moon and Leo

Leo’s brightest star, Regulus, stands above the Moon tonight. Algieba, a binary system that marks the lion’s forehead, is farther to the upper right of Regulus.

May 23: Moon and Jupiter

Jupiter stands close to the upper right of the Moon this evening, shining like a brilliant star. The giant planet will be about the same distance to the right of the Moon tomorrow night.

May 22: Moon and Companions

The crescent Moon stands at the middle of a beautiful grouping this evening. Venus, the “evening star,” is to the lower right of the Moon, with the giant planet Jupiter about the same distant to the upper left. The twins of Gemini are above Venus.

May 21: Moon and Venus

Venus teams up with the Moon to put on a grand showing this evening. Venus is the brilliant “evening star” to the right of the Moon as night falls. It far outshines all the other planets and stars in the night sky, so you can’t miss it.
