A simulated night sky looking west on June 4, 2026, one hour after sunset. Jupiter and Venus are prominent in the upper center, with Venus appearing brighter. The twin stars Castor and Pollux are visible in the upper portion. Mercury appears near the horizon to the lower right, and Procyon is visible to the lower left. The horizon shows a dark silhouette of trees against a warm twilight glow.

A simulated night sky looking southeast on June 3, 2026, at 3 A.M. The bright Moon glows prominently at center right. To the upper left, the star Altair is labeled, and a red asterisk-like symbol marks the position of the asteroid Juno. The Milky Way is faintly visible as a dark cloud-like region in the upper portion.

A telescopic simulation of Saturn as seen on June 2, 2026, at 4 A.M. CDT. Saturn is centered with its rings clearly visible, tilted slightly. Four moons are labeled around it: Titan to the upper left, Rhea and Dione to the left, and Enceladus to the right. A scale bar indicates 36 arcseconds. North and East compass directions are marked in the upper left corner.

The Sky Today on Tuesday, June 2: Titan stands close to Saturn

No matter how many Full Moons appear in any given timespan, its color will not actually change to blue. Credit: John Chumack.

Observing, The Moon

What is a Blue Moon? When’s the next one?

A simulated twilight sky looking west on June 1, 2026, 30 minutes after sunset. Venus shines brilliantly near center, with Jupiter visible to its upper left. Mercury is faintly visible low on the right against the warm orange twilight. The twin stars Castor and Pollux are labeled faintly near the top.

The Sky Today on Monday, June 1: Mercury at its best

Two bright planets — Venus and Jupiter — shine as close points of light in a deep blue twilight sky above an illuminated city skyline at dusk. The city's skyscrapers, tower, and sprawling lights glow against a gradient sky that fades from deep blue above to lighter blue near the horizon, with low clouds hugging the rooftops.

June 2026: What’s in the sky this month?

A twilight photograph taken from the shore of a calm lake, looking toward a park with trees, streetlights, and a tall flagpole silhouetted against a deep blue and orange dusk sky. Three planets — Venus, Mercury, and Jupiter — are visible as bright points of light in the sky, with two clustered close together near the horizon and one higher up. Their reflections shimmer faintly in the still water below, which is dotted with aquatic plants.

June 2026: What’s in the Southern Hemisphere sky this month?

A simulated night sky looking southwest on May 31, 2026, at 4 A.M. A Full Moon sits just below the reddish star Antares, the heart of the constellation Scorpius, against a very dark sky with few other stars visible.

The Sky Today on Sunday, May 31: Blue Moon, red star

A simulated night sky looking east on May 30, 2026, one hour after sunset. The bright orange star Arcturus, alpha star of the constellation Boötes, is prominently labeled near the center. Several Greek letter designations mark nearby stars of the constellation. A crescent Moon is visible low on the right horizon.

The Sky Today on Saturday, May 30: Fly a cosmic kite

A wide-field view of M44, the Beehive Cluster, showing a loose, sprawling grouping of bright, individually resolved stars scattered across the center of the frame. The cluster's most prominent members are large, brilliant blue-white stars, contrasted by several warm orange and golden stars interspersed among them. The cluster has no tight central concentration, spreading openly across the field with a rich background of much fainter stars visible throughout the deep black sky.

A sky chart showing the northeastern sky on May 29, 2026, at 10 PM. The bright star Vega is labeled and visible toward the right-center of the image, and a small white arrow near the top points to the star Nu Draconis. The sky fades from deep blue-black above to a lighter blue near the horizon, with a silhouetted building and treeline along the bottom.

The Sky Today on Friday, May 29: Split Nu Draconis

A large Full Moon rises behind trees at left, glowing bright white against a deep blue night sky. To the right, the illuminated Baroque dome and bell tower of the Basilica of Superga in Turin, Italy are lit in warm golden light, creating a dramatic contrast with the moonlit sky.
