Messier 106 and companions646 viewsThe large spiral galaxy at left is M106, lying at a distance of 22 to 25 million light-years from Earth in the constellation Canes Venatici. A myriad of other galaxies are in the frame, of which the two most prominent are NGC 4248 (closest to M106) and NGC 4217 (disk at right).

NGC 3521, "flocculent" spiral galaxy in Leo646 viewsNGC 3521 is termed a "flocculent" spiral galaxy because it has patches or clumps of stars breaking up the continuity of the spiral arms. Self-propagating star formation is thought to account for the patchiness. The galaxy lies about 26 million light-years away from us.

The earthy chill of dusk and slow
Upon those under lands the vast
And ever climbing shadow grow

NGC 2359 - Thor's Helmet642 viewsAn emission nebula in the constellation Canis Major; about 12,000 light-years away. Consists largely of interstellar gas swept up by the central star, and partly of material from the star itself, which is an extremely hot, massive Wolf-Rayet star in a short-lived pre-supernova stage.
