Evening Planets

Venus makes its descent into the western horizon soon after sunset. Act quickly to catch a glimpse of it with a telescope.
Saturn and Mars grace the southern sky in the evening. Watch them move into the west as the night progresses.

Constellations and Deep-Sky Objects

Looking toward the south, we’ve turned away from the crowded center of our Milky Way Galaxy. Thus we see farther into the universe.
The large constellation Virgo fills the southern sky in the late evening. One of the zodiacal constellations of ancient times, Virgo honors the life-giving virtues of women.
Using a pair of binoculars, visit the Virgo Cluster of Galaxies. These tiny smudges of light are galaxies, far away from our own Milky Way, each aglow with the light of billions of stars.
The Sombrero Galaxy, M104, lies in the southern part of Virgo. Its dark dust lane makes it look like a large hat, hence its name.
Two smaller constellations lie above Virgo.
Coma Berenices honors a queen who gave her long hair to the gods to ensure her husband’s safe return from war. M64, a spiral galaxy, can be found tangled in Berenice’s Hair.
Canes Venatici represents the hunting dogs of the gods. The brightest star in Canes Venatici is Cor Caroli, the Heart of Charles, named for Charles 1 of England.
M51, in Canes Venatici, is known as the Whirlpool Galaxy. It is one of the most beautiful face-on spirals in the sky.


The Eta Aquarid meteor shower peaks on the morning of May 6th. Look toward the eastern sky after midnight to see up to 10 meteors per hour. The full Moon may wash out all but the brightest meteors.
On May 20th, sky watchers in southern China, Japan, and the western United States will be treated to an annular solar eclipse. Observers in other parts of eastern Asia and most of North America will see this event as a partial eclipse.

The night sky is always a celestial showcase. Explore its wonders from your own backyard.
