About NGC 7479
Description
NGC 7479 is a barred spiral galaxy in Pegasus, about 105 million light-years away. It has a striking S-shaped spiral pattern with a strong central bar, making it one of the finest barred spirals for astrophotography.
Observing Tips
Visible as a moderately bright, elongated glow in an 8-inch telescope. The bar structure may be glimpsed at 12 inches under excellent conditions. Best in autumn evenings at medium magnification.
History
Discovered by William Herschel on October 19, 1784. A supernova (SN 1990U) was observed in this galaxy in 1990.
Fun Facts
Radio observations reveal a jet from the galaxy's nucleus that appears to curve in the opposite direction from the optical spiral arms, suggesting the galaxy experienced a minor merger that reversed the winding direction.
