Encyclopedic overview
NGC 774 is a lenticular galaxy in the constellation Aries. The galaxy lies about 180 million light years away from Earth, which means, given its apparent dimensions, that NGC 774 is approximately 70,000 light years across. It was discovered by William Herschel on October 16, 1784.
NGC 774 is a lenticular galaxy. The nucleus of the galaxy is a faint source of [NII]6584 and H-alpha emission. A ring is visible in ultraviolet. The ring is possibly a place of active star formation, as it was the location of a core-collapse supernova. Ionised gas is located asymmetrical around the nucleus, at a distance up to 20 arcseconds, which corresponds to 6 kpc at the distance of the galaxy. Stellar kinematics indicate it has a double stellar ring. A faint dust ring is also visible.
