In the Sky This Month

The Moon stages some especially close encounters with several stars and planets this month. It teams up with Saturn and Mars in the dawn sky, along with Neptune, which is too faint to see with the eye alone. Mercury creeps in there as well, but it’s difficult to spot. The Moon snuggles especially close to Antares, the bright orange heart of the scorpion, near month’s end. The Summer Triangle begins to climb into the evening sky, along with Libra, the balance scales, a lead-in to the prominent summer constellation Scorpius. On the other hand, Leo, the lion, plunges head first toward the southwestern horizon.

The full Moon of May is known as the Milk Moon, Flower Moon, or Corn Moon.

Fuzzy Foot

The twins of Gemini are dropping feet-first toward the western horizon as night falls. One of those feet is marked by a small, faint smudge of light: the star cluster M35. It is about 2,500 light-years away and contains about 150 stars.

The Fox

Vulpecula, the fox, rises in late evening. The constellation is quite faint. Its brightest star — a red giant more than 200 light-years from Earth — is visible to the unaided eye only from a dark location, away from city lights.

More Moon and Venus

The planet Venus, which blazes as the “morning star,” perches quite close to the crescent Moon at dawn tomorrow. Venus is the brightest object in the night sky other than the Moon, so you can’t miss it.

Moon and Venus

Look for the Moon before sunrise tomorrow, with Venus, the “morning star,” to its lower left. Despite its moniker, Venus is a planet, not a star. In fact, it’s our closest planetary neighbor, passing as close as 27 million miles away.

Sky Test

The Big Dipper is high in the north as night falls, standing upside down. If you line up the two stars at the outer edge of the bowl and follow that line to the lower right, the first bright star you come to is Polaris, the North Star.

Vega Rising

Vega, one of the harbingers of summer, peeks above the northeastern horizon by around 9 p.m. Vega is one of the brightest stars in the night sky, and one of our closest stellar neighbors, at a distance of about 25 light-years.

Beta Ceti

Cetus, the whale or sea monster, is in the south and southwest at nightfall. Its brightest star, Beta Ceti, is the second-brightest star in a wide swath of sky. It’s outshined only by Fomalhaut, which is quite low at that hour.

Camelopardalis

Camelopardalis, the giraffe, is one of the largest constellations, covering a big wedge of the northern sky. But it isn’t very bold. All of its stars are so faint that you need to get away from city lights to see them.

Moon and Planets

The Moon and two bright planets form a beautiful triangle at dawn tomorrow. Brilliant Jupiter stands to the right of the Moon, with fainter orange Mars close below them.

Vanishing Venus

Venus will pass behind the Sun today, so it is lost from view in the Sun’s glare. It will return to view next month, when it will shine as the brilliant Evening Star.
