Discovered (Apr 25, 1784) by
William Herschel
A 12th-magnitude spiral galaxy (type SB(s)cd) in Virgo (RA 12 51 01.0, Dec -06 23 33)
The first IC adds "William Herschel in 1784 described it as 'a little brighter middle', not 'suddenly brighter middle', as in the GC. There has apparently not been any change; it is diffused, without condensation. The RA in NGC (per John Herschel) is correct (Armagh, 2 observations)". Based on a recessional velocity of 1490 km/sec, NGC 4731 is about 70 million light years away, in good agreement with redshift-independent distance measurements of 45 to 85 million light years in diameter. This probably makes it a member of the Virgo Cluster of galaxies, even though it is not listed in the Virgo Cluster Catalog. Given its probable distance and its apparent size of 6.6 by 3.2 arcmins, the galaxy is about 125 thousand light years across. The distortion of NGC 4731's spiral arms is believed to be due to gravitational interaction with giant elliptical galaxy NGC 4697, shown in the widest-field image below.

NGC 4736 (=
M94 = PGC 43495)
Discovered (Mar 22, 1781) by Pierre Méchain
Observed/recorded (Mar 24, 1781) by Charles Messier as M94
Also observed (Apr 28, 1827) by John Herschel
A magnitude 8.2 spiral galaxy (type (R)SA(r)ab?) in Canes Venatici (RA 12 50 53.1, Dec +41 07 17)
Historical Identification: Per Dreyer, NGC 4736 (= GC 3258 = JH 1456, Méchain, M94, 1860 RA 12 44 17, NPD 48 07.0) is "very bright, large, irregularly round, very suddenly very much bright middle and bright nucleus, mottled but not resolved". The position precesses to RA 12 50 53.2, Dec +41 07 14, essentially dead center on the galaxy listed above and the description fits, so the identification is certain.
Physical Information: The 310 km/sec recessional velocity of M94 is too small in comparison to peculiar (non-Hubble expansion) velocities to provide a reliable distance indicator, but as it happens, does suggest a distance in line with redshift-independent distance estimates of 14 to 21 million light years. Using the most commonly accepted distance of 15 million light years, the galaxy's 11 by 9 arcmin wide central region corresponds to about 50 thousand light years, but the outer ring, which covers the best part of 18 arcmin, extends another 30 thousand light years or so. Recent infrared and ultraviolet studies show that the outer ring is only the most visible portion of a complex system of spiral arms, presumably caused by self-induced gravitational instabilities (M94 appears to be a "field" galaxy, with no nearby galaxies which could provide a signficant gravitational interaction). The core of the galaxy contains a 7000 light year wide ring of exceptionally hot, bright young stars which must have formed in a "starburst" less than 10 million years ago. Because of the intense radiation of this central ring, M94 is classified as a Seyfert galaxy (type Sy 2).
