Galactic core region of the Milky Way shining over Sofa Mountain, Waterton Lakes National Park, Alberta, Canada. The lower part of the Galactic Dark Horse, called the Pipe nebula (B78), is at right. The Large Sagittarius starcloud is at lower centre over the mountain ridge, and very yellow because of interstellar dust absorption; the whiter Small Sagittarius starcloud (M24) is at top, flanked by the large star clusters M23 at right and M25 at left. The pink Lagoon nebula (M8) is at centre, with the bluish Trifid Nebula (M20) above. The globular star cluster M22 is at lower left. Taken on June 1, 2021. |
