Hubble Zooms In on NGC 891's Northern Half

Posted on May 21, 2012

The Hubble Space Telescope turned its powerful wide field Advanced Camera for Surveys towards the NGC 891 spiral galaxy and took a close-up of its northern half. The galaxy, which spans 100,000 light-years, is seen exactly edge-on in the image.

Astronomers believe the filaments of dust and gas escaping the plane of the galaxy into its halo are the result of the ejection of material due to supernovae or intense stellar formation activity. The galaxy is located in the constellation Andromeda. You can see a larger version of the image here.
