A silver spacecraft floating in space.

We're in the process of performing a scheduled migration of the NASA Hubble mission information from hubblesite.org to nasa.gov/hubble. During this time, you may experience temporary unavailability.

Please visit the NASA Hubble mission page to learn about Hubble.

Thank you for your patience.

The Andromeda galaxy, a spiral galaxy, spreads across the width. It is tilted nearly edge-on to our line of sight so that it appears as an extreme oval on its side. The borders of the galaxy are jagged because the image is a mosaic of smaller, square images. The outer edges are blue, while the inner two-thirds are yellowish with a bright, central core. Dark, dusty filamentary clouds wrap around the outer half of the galaxy’s disk. At 10 o'clock, a smaller dwarf elliptical galaxy forms a fuzzy, yellow blob. Hubble's sharp vision distinguishes about 200 million stars within the image. The background of space is black. There are what appears to be steps toward the bottom, mainly toward the middle, which indicates where no data were taken.
