Wide-field view: Irregular Spiral Galaxy NGC 922 in Fornax | Digitized Sky Survey 2

This image from a ground-based telescope shows the region around NGC 922, a galaxy with a bright ring of nebulae caused by a collision with another, smaller galaxy. It passed straight through NGC 922 around 330 million years ago. This smaller galaxy, called 2MASXI J0224301-244443 is visible as a small blob to the right of NGC 922, the bright galaxy in the center of the field. The orange line crossing the image is a satellite passing above the telescope during the observations.

Distance from Earth: 150 million light years

The Digitized Sky Survey (DSS) is a ground-based imaging survey of the entire sky in several colors of light produced by the Space Telescope Science Institute through its Guide Star Survey group.
