C67 소개
설명
NGC 1097 is a barred spiral galaxy in Fornax, about 45 million light-years away. It is a Seyfert galaxy with an active nucleus, and Hubble images reveal a spectacular nuclear ring of star formation about 5,000 light-years in diameter.
관측 팁
Visible as a moderately bright, elongated glow in a 6-inch telescope from dark sites. The bar structure is visible in 10-inch scopes. Best observed from southern or tropical locations in autumn evenings when Fornax is well placed.
역사
Discovered by William Herschel on October 9, 1790. It was one of the first galaxies identified as having jets emanating from its nucleus, visible in deep photographs.
재미있는 사실
NGC 1097 is consuming a smaller companion galaxy, NGC 1097A, which orbits within its halo. The nuclear starburst ring is fueled by gas funneled inward along the galaxy's bar.
