Description

1.5-billion-pixel view of the Andromeda Galaxy. The highest-resolution photo ever captured of space has 1,000 times the resolution of a normal high-definition picture. Andromeda, just 2.5 million light years away from our own Milky Way Galaxy home -- a near neighbor in cosmic terms -- was chosen as the ideal candidate for the high-resolution image, and the resulting image is a new benchmark for precise study of a large spiral galaxy, astronomers say. Even from millions of light years away, the strength of the Hubble telescope is enough to show individual stars within a 61,000-light-year-long swathe of the galaxy's pancake-shaped disk. "Never before have astronomers been able to see individual stars inside an external spiral galaxy over such a large contiguous area," NASA says on its website. http://www.nasa.gov/content/goddard/hubble-s-high-definition-panoramic-view-of-the-andromeda-galaxy/ The level of detail in the image, which shows 100 million stars, is "like photographing a beach and resolving individual grains of sand," NASA said. The photo can be downloaded from NASA's Hubble site, allowing individuals to zoom in and out on the image of a 61,000 light year-long panorama of Andromeda. http://hubblesite.org/newscenter/archive/releases/2015/02/image/a/
