Zoom into the Andromeda galaxy The largest NASA Hubble Space Telescope image ever assembled, this sweeping view of a portion of the Andromeda galaxy (M31) is the sharpest large composite image ever taken of our galactic neighbor. Though the galaxy is over 2 million light-years away, the Hubble telescope is powerful enough to resolve individual stars in a 61,000-light-year-long section of the galaxy's pancake-shaped disk. It's like photographing a beach and resolving individual grains of sand. An

What does Andromeda sound like? Scientists have converted light from various wavelengths into sound, creating a "soundtrack" of the Andromeda galaxy. Data from powerful telescopes—from Chandra X-rays to radio waves—have been translated into musical notations: high-energy X-rays sound like high tones, and low-energy radio waves like deep bass. | Jock Williams Meteorologist
