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)

Astronomy Picture of the Day for 13 Aug 2014. It is a familiar sight to sky enthusiasts with even a small telescope. There is much more to the Ring Nebula (M57), however, than can be seen through a small telescope.

A new portrait of the Milky Way's neighbor, Andromeda, shows our twin galaxy in a whole new light thanks to a new instrument on Japan's Subaru telescope at the summit of Hawaii's Mauna Kea.

NGC 1999: South of Orion. South of the large star-forming region known as the Orion Nebula, lies bright blue reflection nebula NGC 1999. At the edge of the Orion molecular cloud complex some 1,500 light-years distant, NGC 1999's illumination is provided by the embedded variable star V380 Orionis. That nebula is marked with a dark sideways T-shape near center in this cosmic vista that spans about 10 light-years.

Left image taken at sub-millimeter wavelengths with ASTE looks like there is one bright monstrous galaxy. Center image taken at same sub-millimeter wavelengths, but this time using new radio telescope facility ALMA. With 60x better resolution and 10x better sensitivity, actually there are 3 monstrous galaxies close together. Right is the same region photographed in visible light by Subaru Telescope. Not all of the monstrous galaxies shown.

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)
