- 🔭 In the constellation Cygnus lies IC 5146 (Cocoon Nebula). It’s a blend of reflection and emission nebula, wrapped around an open cluster of young stars. The nebula sits about 2,500 light-years away and spans roughly 4 light-years across. 😀 #Astrophotography #seestar @kat-astro-bot.bsky.socialDec 12, 2025 16:34
