NGC 3430 is a barred spiral galaxy in the constellationofLeo. Its velocity with respect to the cosmic microwave background is 1,869 ± 20 km/s, which corresponds to a Hubble distance of 27.6 ± 2.0 Mpc (∼90 million light-years).[1] It was discovered by German-British astronomer William Herschel on 7 December 1785.
NGC 3430 is classified as a well-known example of an SAc spiral galaxy with no central bar structure but has spiral arms found open and clear-defined.[2] Moreover, it is also a Wolf-Raynet galaxy, with star-forming regions[3] and forms a pair with NGC 3424, a nearby starburst galaxy.[4] According to a 1997 study presented by researchers, these galaxies are clearly showing signs of tidal interaction.[5]
Two supernovae have been observed in NGC 3936: SN 2004ez (type II, mag. 17.3),[6][7] and PSN J10520833+3256394 (type IIb, mag. 17.8).[8]
