61,000 light-year-long swath of the Andromeda galaxy

GALACTIC CLOSE-UP  A 61,000 light-year-long swath of the Andromeda galaxy appears in this mosaic of more than 7,000 images from the Hubble Space Telescope.

SEATTLE  The Andromeda galaxy is ready for its close-up.

The closest spiral galaxy to the Milky Way appears in unprecedented detail in a new mosaic of images from the Hubble Space Telescope presented January 5 at the American Astronomical Society meeting. The final composite is a 61,000-light-year-long panorama of our galactic neighbor encompassing the light of nearly 117 million stars.

Even though Andromeda is over 2 million light-years away, the picture contains enough detail to reveal individual stars and star clusters. The center of the galaxy, filled with old red stars, sits to one side of the image. Spiral arms, home to Andromeda’s stellar nurseries, encircle the mostly dead core with young, blue stars and tendrils of dark dust. 

The image is a result of the Panchromatic Hubble Andromeda
