Zubeneschamali and Zubenelgenubi skitter across the southern sky on May evenings. They are far above Antares, the bright heart of the scorpion, which climbs into view by about 10 p.m.
Although they're in Libra, they represent the claws of the scorpion.

Two of the brightest planets in the sky are slowly moving toward one unforgettable meeting. ✨

Every evening between now and June 9, Venus and Jupiter will appear closer together in the western twilight, shrinking the gap night after night until they almost seem to touch.

Tonight, they still sit comfortably apart.
By the end of May, the distance between them will narrow dramatically. And on June 9, the pair will glow just 1.6° apart, close enough to fit beneath two fingertips held at arm’s length.

But there’s another reason to keep watching.

Beginning May 27, tiny Mercury returns low in the northwestern sky below Venus, briefly joining the planetary gathering before disappearing again into twilight. It’s the smallest planet in our solar system, and one of the hardest to catch without a perfectly clear horizon.

This is one of those rare sky stories that changes every single night.
Step outside after sunset and watch the planets slowly rewrite the western sky.

Save this, best night to observe is June 9.

As night falls, look in west for Procyon, the brightest star of Canis Minor, the little dog. It’s to the lower left of much brighter Jupiter, the Sun’s largest planet. Procyon sets by about midnight.

: Flower Moon, 2026

Photographer Josh Dury captured this gorgeous view of the Flower Moon on May 1, 2026, hanging above a cherry tree in full bloom and giving weight to the origin of the moon's name.

"May Day; the second quarter day. With rich smells and colours all around, it is yet another signal that solstice is not far away. Within the period of this lunar cycle - flowers come, flowers go. From vibrant blossom displays, to moonlight stretching across a carpet of bluebells."
