NGC 772: The Fiddlehead Galaxy — APOD for 2025-03-12

Why does this galaxy look like a curly vegetable ? 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 toward the constellation of the Ram (Aries). But in the featured image , the Fiddlehead appears to have another companion -- one with a long and fuzzy tail: Comet 43P/Wolf-Harrington . Though the comet appears to be aimed straight at the massive galaxy, it is actually much closer to us, residing only light minutes away -- well within our Solar System. The comet will never reach the distant spiral galaxy, nor is it physically related to it. By a fortunate trick of perspective, though, these two cosmic wonders briefly share the same frame taken late last year from Calern , France .
