Actually NGC 7023 is the star cluster inside the nebula, which is properly designated LBN 487.Jan 31, 2022 The Horsehead Nebula in Orion233 viewsThe Horsehead Nebula, Barnard 33, is a dark nebula, silhouetted against the bright emission nebula IC 434. The large blue object to the left of IC 434 is a reflection nebula, NGC 2023. They are all found near the star Alnitak, the easternmost star in Orion's belt, which is off the frame to the right, and are 1400 light-years from Earth.Jan 18, 2022 Sharpless 2-155 - The Cave Nebula297 viewsA narrowband (Hubble Palette) view of an emission nebula in Cepheus; part of an ionized HII region within a larger complex containing emission, reflection and dark nebulae. About 2400 light-years away, on the edge of the Cepheus molecular cloud.Dec 22, 2021 NGC 1977, The Running Man Nebula in Orion238 viewsA reflection nebula embedded in a bright HII region, Sh2-171, found in Orion's Sword near the Great Orion Nebula M42. Sh2-171 also includes two other nebulae and the star cluster NGC-1981. Dec 21, 2021 Sharpless 2-171, The Teddy Bear Nebula in Cepheus349 viewsAn emission nebula, part of a larger nebula designated NGC 7822, about 2900 light years away.Dec 07, 2021 NGC2237 - The Rosette Nebula232 viewsEmission Nebula / HII region in Monoceros, with open cluster NGC 2244 in center of nebula. Jun 26, 2021 IC 4604 - Rho Ophiuchi Nebula 230 viewsA blue reflection nebula in Ophiuchus, illuminated by three bright stars of which the central and brightest is Rho Ophiuchi. Lying along the border of Ophiuchus and Scorpius, this nebula and its neighbor IC4603 are close to the giant red star Antares.Jun 23, 2021 IC4603 - Core of the Rho Ophiuchi Complex260 viewsThis blue reflection nebula glows by the light of the 7.9 magnitude star SAO184376 in the center. Jun 22, 2021 IC1396A - Elephant Trunk Nebula 320 viewsA narrowband (Hubble Palette) image of a dense cloud of gas and dust within a much larger region of ionized gas designated IC1396, illuminated and ionized by the massive bright star HD206267 at the upper right corner of the frame. I don't find that the shape of the nebula resembles an elephant's trunk, but rather, as Michelle Evans has suggested, a dragon named Verminthrax Pejorative from the movie Dragonslayer. Jun 22, 2021 IC4592 - Blue Horsehead Nebula 195 viewsReflection nebula in the constellation Scorpius, lit by the giant septuple star Jabbah (Nu Scorpii). This photo shows only part of the nebula, so the horsehead shape is not evident here.Jun 09, 2021 NGC 6543 - Cat's Eye Nebula246 viewsA structurally very complex planetary nebula about 3000 light-years from Earth in the constellation Draco. In large-telescope images it has the appearance of a cat's eye, but in my 5" refractor it appears simply as a bright blue star with a halo. The small spiral galaxy off to the left is probably NGC 6552.Feb 04, 2021 M15 - Globular cluster in Pegasus246 viewsContaining over 100,000 stars, 175 light-years in diameter, 33,600 light years from Earth. This is one of the oldest (12 billion years) and most densely packed globulars in the Milky Way.Sep 14, 2020 161 files on 14 page(s) 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Debug Info  Debug Output: show /
