NGC 3994 is an unbarred spiral galaxy in the constellation Ursa Major. The galaxy lies about 160 million light years away from Earth, which means, given its apparent dimensions, that NGC 3994 is approximately 70,000 light years across. [1] It was …

NGC 3994 is a Spiral Galaxy in the Ursa Major constellation. NGC 3994 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its visual magnitude of 12.87, NGC 3994 is visible with the help of a telescope having an aperture of 10 inches (250mm) or more.

2020年4月30日 · Historical Identification: Per Dreyer, NGC 3994 (= GC 5595, d'Arrest, 1860 RA 11 50 25, NPD 56 56.1) is "pretty bright, very small, 2nd of 3", the others being NGC 3391 and 3395. Physical Information:

2022年3月22日 · NGC 3994 and NGC 3991 called ARP 313. ARP 313 consists of 10 Galaxies in a distance of about 145 mio Lj. The main ones are: in the right corner down is the Galaxy Leda/PGC 1981745 (0,38 x 0,21 arcmin - 18m0) which are the two patches on the right side. The small 3rd patch on the left side is another galaxy far away.

NGC 3994 is an Active Galactic Nuclei/Nucleus located in the constellation of Ursa Major in the northern hemisphere. NGC 3994 is called NGC 3994 in the New General Catalogue (NGC). This catalogue is a list of deep space objects compiled by John Louis Emil Dreyer in 1888 to update John Herschel's earlier work. NGC 3994 is not a Messier Object ...

NGC 3994 is a LINER. All three galaxies have strong ultraviolet emission and have been observed with IUE (Kinney, et al. 1993). As part of an investigation of star formation in interacting galaxies, we have obtained ultraviolet and visible images of the central regions of NGC 3994 and 3995 with the Space Telescope Imaging Spectrograph on HST.

NGC 3991 is the shred-like string of star-forming regions at the northwest corner, and NGC 3994 is the spiral with an internal ring of star-forming region at the southern end of this little grouping. NGC 3995 is also distinguished by having an extraordinarily small rotation velocity - if it is really a disk seen almost edge-on, it has only one ...
