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.
2025 March 12
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.
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.
