When the New General Catalog was done, in the late 1800's and early 1900's, NGC numbers were assigned in order of right ascension, so NGC 1 had the smallest right ascension, NGC 2 the next smallest, and so on. Since then, precession has altered the positions of the Poles and the...
Physical Information: The Eagle Nebula and the young star cluster associated with it are about 7000 light-years away, meaning we see them as they were 7000 years ago. But up to the left of the brightest part of the nebula, where the star cluster is centered, is a violently expanding clou...
In the default configuration, the standardization engine expects street address and business names to be in free-form text fields that need to be parsed prior to normalization and phonetic encoding. Person and phone information can also be contained in free-form text fields, but theses types of ...
(Corwin notes that Herschel's more detailed description states that there are three 9th magnitude stars "nearly in the parallel", meaning aligned east-west along nearly the same line of declination, "joined by a rich clustering portion of the Milky Way", which Corwin states seems closer to ...
A 5th-magnitude open cluster (type II2mn) in Sagittarius (RA 18 04 30.0, -24 21 30) Historical Identification: Per Dreyer, NGC 6530 (= GC 4366 = JH 3725, 1860 RA 17 56 06, NPD 114 20.0) is "a cluster, bright, large, pretty rich, to the east of M8", meaning to the east...
in 1851 Bindon Stoney, working for the 3rd Lord Rosse, recorded a "great many knots, reckoned 10 nearly in a line pf", meaning running east and west. As shown in the image above there are six galaxies running in a nearly east-west line in the area in question, two of which are ...
It lists both PGC 15042 and PGC 15034 as NGC 1568: (meaning, as part of the NGC object). Above, a 4 arcmin wide closeup of NGC 1568Below, a 12 arcmin wide region centered on the pair PGC 15034 (not part of NGC 1568) Not an NGC object but listed here since ususally ...
Per Corwin, Swift's note read "in vacancy", meaning that there was nothing else near his #42, so there is no doubt that this is a reobservation of NGC 4351. Given that, it is hardly surprising that Frost was unable to find a second object in the field, nor that the identity with...
Historical Identification: Per Dreyer, NGC 1891 (= GC 1099 = JH 2811, 1860 RA 05 16 21, NPD 125 51.6) is a "cluster, large, scattered, double star taken", the last comment meaning that the position of the cluster is taken as that of the double star. ...
Historical Identification: Per Dreyer, NGC 979 (= GC 564 = JH 2486, 1860 RA 02 26 27, NPD 135 08.4) is "faint, small, round, between 2 stars in parallel", in parallel meaning on the same parallel of declination (that is, to the east and west of the nebula). ...
