the green bean galaxy j2240 lies in constellation of aquarius


because of position away galactic plane, majority of deep-sky objects in aquarius galaxies, globular clusters, , planetary nebulae. aquarius contains 3 deep sky objects in messier catalog: globular clusters messier 2, messier 72, , open cluster messier 73. 2 well-known planetary nebulae located in aquarius: saturn nebula (ngc 7009), southeast of μ aquarii; , famous helix nebula (ngc 7293), southwest of δ aquarii.


m2, catalogued ngc 7089, rich globular cluster located approximately 37,000 light-years earth. @ magnitude 6.5, viewable in small-aperture instruments, 100 mm aperture telescope needed resolve stars. m72, catalogued ngc 6981, small 9th magnitude globular cluster located approximately 56,000 light-years earth. m73, catalogued ngc 6994, open cluster highly disputed status.


aquarius home several planetary nebulae. ngc 7009, known saturn nebula, 8th magnitude planetary nebula located 3,000 light-years earth. given moniker 19th century astronomer lord rosse resemblance planet saturn in telescope; has faint protrusions on either side resemble saturn s rings. appears blue-green in telescope , has central star of magnitude 11.3. compared helix nebula, planetary nebula in aquarius, quite small. ngc 7293, known helix nebula, closest planetary nebula earth @ distance of 650 light-years. covers 0.25 square degrees, making largest planetary nebula seen earth. however, because large, viewable faint object, though has high integrated magnitude of 6.0.


one of visible galaxies in aquarius ngc 7727, of particular interest amateur astronomers wish discover or observe supernovae. spiral galaxy (type s), has integrated magnitude of 10.7 , 3 3 arcseconds. ngc 7252 tangle of stars resulting collision of 2 large galaxies , known atoms-for-peace galaxy because of resemblance cartoon atom.
