In the Sky This Month

Of the five planets easily visible to the unaided eye, only Mercury is missing from view this month. The other four are in good view, with one of them, Jupiter, putting in its best showing of the year. Venus climbs higher as the Evening Star, while Mars and Saturn remain in the early morning sky. Among the stars, Regulus and Spica climb to their full spring glory.

May 25: Moon and Spica

Spica, the leading light of Virgo, perches to the lower right of the Moon at nightfall. It is one of the brighter stars in the sky, and it’s not close to any other bright stars, so it stands out.

May 26: Moon, Jupiter, Spica

The Moon slides between two bright lights tonight. The planet Jupiter is close to the lower left of the Moon at nightfall. It’s brighter than anything in the night sky except the Moon and Venus. The star Spica is farther to the right of the Moon.

May 27: Moon and Jupiter

Jupiter, the largest planet in the solar system, looks like a brilliant star close to the right of the Moon at nightfall. It stays close to the Moon throughout the night.

May 28: Western Lights

Three bright lights line up parallel to the western horizon this evening. The center light is also the brightest: Venus, the “evening star.” The star Capella is far to the right of Venus, with the star Procyon about the same distance to the left of Venus.

May 29: Moon and Antares

Antares, the leading light of the constellation Scorpius, is in good view tonight, to the right of the full Moon as darkness falls. Antares is a supergiant — one of the biggest and brightest stars in the galaxy.

May 30: Moon and Saturn

Saturn is in good view the next couple of nights. The planet looks like a bright star, and stands to the lower left of the Moon as they climb into view late this evening. It will stand closer to the right of the Moon tomorrow night.

May 31: More Moon and Saturn

The bright planet Saturn rises shortly before the Moon late tonight, and precedes the Moon across the sky. It will stand close to the upper right of the Moon as they rise, and a bit farther to the lower right at first light.
