The Andromeda Galaxy (M31) ~ A massive spiral 2.5 million light-years away, over twice the diameter of our own Milky Way, it's the largest nearby galaxy. Andromeda's population of bright young blue stars lie along its sweeping spiral arms. (Spitzer Space Telescope)

Omega Nebula ~ Sculpted by stellar winds and radiation, the star factory also known as Messier 17 lies some 5,500 light-years away in the nebula-rich constellation Sagittarius. The sharp, composite, color image shows faint details of the region's gas and dust clouds against a backdrop of central Milky Way stars. (Subaru Telescope (NAOJ), Hubble Space Telescope)
One of the brightest galaxies in planet Earth's sky is similar in size to our Milky Way Galaxy: big, beautiful M81. This grand spiral galaxy can be found toward the northern constellation of the Great Bear (Ursa Major). This superbly detailed view reveals M81's bright yellow nucleus, blue spiral arms, and sweeping cosmic dust lanes with a scale comparable to the Milky Way. Hinting at a disorderly past, a remarkable dust lane actually runs straight through the disk, to the left of the ...
There is much more to the Ring Nebula (M57) than can be seen through a small telescope. The easily visible central ring is about one light-year across, but this remarkably deep exposure - a collaborative effort combining data from three different large telescopes - explores the looping filaments of glowing gas extending much farther from the nebula's central star.
