Astronomy Picture of the Day

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

A dark field is filled with stars and galaxies. A large spiral galaxy appears on the upper left. Toward the right, there is a smaller fuzzy patch that is a comet with a short tail. Please see the explanation for more detailed information.A dark field is filled with stars and galaxies. A large spiral galaxy appears on the upper left.

NGC 772: The Fiddlehead Galaxy

Explanation: 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 .
