The Fiddlehead spiral galaxy likely gets its distorted spiral appearance from a gravitational interaction with its close-by elliptical companion NGC 770, seen just below. Cataloged as NGC 772 and Arp 78, the Fiddlehead spans over 200,000 light years, is a nearby 100 million light years beyond the stars of our Milky Way galaxy, and is visible ...

NGC 772, located within the Aries constellation, emerges as a celestial marvel situated at a staggering distance of 130 million light-years from earth. This spiral galaxy, bedecked with resplendent characteristics, not only enthralls with its aesthetic grandeur but also beckons scientific inquiry.

It is an unbarred spiral galaxy 130 million light years away in Aries. The unusual shape and over arching spiral arm are the result of interaction with neighboring galaxies such as NGC 770. Faint tidal streams stretching out from the outer fringes of NGC 772 can clearly be seen.

NGC 772 (Arp 78) is an unbarred spiral galaxy located in the direction of Aries constellation. It is approximately 130 million light years from Earth. Two supernovae were seen in the galaxy within three weeks in 2003, SN 2003 hl and SN 2003 iq. The galaxy’s coordinates are 01h 59m 19.6s (right ascension) and +19°00’27” (declination).
