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)
In the Center of the Trifid Nebula. Clouds of glowing gas mingle with dust lanes in the Trifid Nebula, a star forming region toward the constellation of the Archer (Sagittarius). In the center, the three prominent dust lanes that give the Trifid its name all come together. Mountains of opaque dust appear on the right, while other dark filaments of dust are visible threaded throughout the nebula. A single massive star visible near the center causes much of the Trifid's glow.
