In the Sky This Month

While the Summer Triangle and the other signature star patterns of the season continue their climb across the night sky, the solar system’s giants stage a dazzling show. Both are at opposition, so they shine at their brightest for the year. Mars shines brightly, too, while Venus dazzles as the Morning Star.

July 10: Moon and Mars

Look for Mars near the Moon the next couple of mornings, high in the sky at first light. Mars is to the upper left of the Moon tomorrow, and to the upper right on Sunday.

July 11: Great Appearances

Jupiter and Saturn, the solar system’s largest planets, are low in the southeast at nightfall and in the southwest at dawn. And the Moon and the planet Mars climb into good view by 1:30 or 2 a.m. Mars looks like a bright orange star to the upper right of the Moon.

Jupiter is putting in its best appearance of the year. The planet is lining up opposite the Sun. It rises around sunset and is in view all night. It also shines brightest for the year. It’s low in the southeast at nightfall and looks like a brilliant star.

The Moon has two bright companions the next couple of mornings. Tomorrow, the planet Venus and the star Aldebaran perch to the lower left of the Moon at first light. Venus is the Morning Star, while Aldebaran represents the eye of Taurus, the bull.

July 16: Moon and Companions II

The planet Venus and the star Aldebaran are close to the right of the crescent Moon at first light tomorrow. Venus is the dazzling Morning Star, which is the brightest object in the night sky other than the Moon. Aldebaran marks the eye of Taurus, the bull.
