Comet C/2025 K1 (ATLAS) glides by the star 9 Herculis in this Aug. 21 image, glowing with a greenish coma about 2′ wide and a 20″ tail. Captured at roughly magnitude 12.5, this icy visitor was 0.33 astronomical units (the average Earth-Sun distance) from the Sun. The image combines 18 minutes of LRGB exposures with a 4-inch scope at f/5.
