Centaurus A Galaxy Seen In Visible & Infrared (2009)

Blend from a visible image of Centaurus A, as seen with the Wide-Field Imager on the MPG/ESO 2.2-meter telescope, and a near-infared view obtained with the SOFI instrument on ESOs New Technology Telescope, also at La Silla. Centaurus A (NGC 5128) is the nearest giant, elliptical galaxy, at a distance of about 12 million light-years. Between 200 and 700 million years ago, this galaxy is believed to have consumed a smaller spiral, gas-rich galaxy — the contents of which appear to be churning inside Centaurus As core, triggering new generations of star birth. The SOFI image was specially processed to look through the dust, providing a clear view of the center and revealing a previously unknown ring of stars and clusters. The field of view is about 4 x 4 arcminutes.
