NGC 578 - a spiral galaxy in the constellation Cetus NGC 578 was discovered on 11 November 1835 by the English astronomer John Herschel . This is the 11th volume of a spiral galaxy of type SAB ( rs) c in the constellation Cetus. Angular dimensions of NGC 578 are 4.8 to 3.0 arcmin . Dreyer directory object is described as a bright , large, very much extended , gradually and rather slowly shining toward the center . Taking into account the available astronomical data concerning the transfer of NGC 578 the red , estimated the average distance of the galaxy from the Solar System , it amounts to about 70 million light-years , ie 21 354 Mpc . NGC 578 observed using the 45 -cm reflector appears to us as an object rather weak , fairly large , elongated in a ratio of 4:3 in a WNW-ESE axis , with a slightly brighter middle and not giving to distinguish between core. A group of stars the size of the fourteenth magnitude is within 1.3 minutes in an easterly direction from the center of the galaxy. It lies just eleven minutes to the south east of the size of the magnitude 7.8 star labeled HD 102122 . Small blue and pink glowing regions where intense young stars are born , are full of starry sparkles . One of the secondary galaxies ( right of center ) is virtually obscured by NGC 578 and it seems to be sticking with it . The fact is many millions of light years away.
