Rosette Nebula
The Rosette Nebula (NGC 2237–39, 2244) is a large H II region and stellar nursery about 5,200 light‑years away in the constellation Monoceros. Spanning roughly 100 light‑years, it consists of a central cavity surrounded by ionized gas illuminated and sculpted by the young star cluster NGC 2244, with pillars, cavities, and ongoing star formation.

Orion's Treasures over Snowy Mountains
27/01/2026
Rising over a frozen valley in the Tatra Mountains, the familiar stars and nebulas of Orion dominate this wide-field nightscape. The featured deep photo was taken in southern Poland's highest mountain range last month, where dark skies and alpine terrain combined to reveal both Earth's rugged beauty and the structure of our galaxy. Above the snowy mountains, Orion's bright belt stars anchor a region of glowing interstellar clouds. The Great Orion Nebula, a vast stellar nursery visible even to the unaided eye, shines near the center of the scene. Surrounding it is the enormous arc of Barnard's Loop, a faint shell of ionized hydrogen gas spanning much of the constellation. To the left, the round Rosette Nebula glows softly, while the grayish Witch Head Nebula hovers to the right, illuminated by nearby starlight. Near the top, the orange supergiant Betelgeuse marks the hunter's shoulder.
