Comet C/2025 R2 (SWAN) Meets Star Queen & Omega Nebulae

Comet C/2025 R2 (SWAN) Meets Star Queen & Omega Nebulae

Astrophotographer Alessandro Carrozzi: "On the evening of October 18, 2025, Comet SWAN (C/2025 R2)—Comet Lemmon's "little sister" – crossed a stunning star field in the heart of the Milky Way, framed by the iconic Eagle (M16/Star Queen) and Omega (M17) nebulae. A beautiful yet challenging image to process, given the crowded and nebulous field."

The Star Queen Nebula (catalogued as Messier 16 or M16, and as NGC 6611, and also known as the Eagle Nebula) is a young open cluster of stars in the constellation Serpens, discovered by Jean-Philippe de Cheseaux in 1745–46.

The Omega Nebula is an H II region in the constellation Sagittarius. It was discovered by Philippe Loys de Chéseaux in 1745.

Italy, officially the Italian Republic, is a country in Southern and Western Europe. It consists of a peninsula that extends into the Mediterranean Sea, with the Alps on its northern land border, as well as nearly 800 islands, notably Sicily and Sardinia. Italy shares land borders with France to the west; Switzerland and Austria to the north; Slovenia to the east; and the two enclaves of Vatican City and San Marino.
