Astronomy news update from NASA :
An example of violence on a cosmic scale, enormous elliptical galaxy NGC 1316 lies about 75 million light-years away
toward Fornax, the southern constellation of the Furnace.
Investigating the startling sight, astronomers suspect the giant galaxy of colliding with smaller neighbor NGC 1317 seen just above, causing far flung loops and shells of stars. Light from their close encounter would
have reached Earth some 100 million years ago.
In the deep, sharp image, the central regions of NGC 1316 and NGC 1317 appear separated by over 100,000 light-years. Complex dust lanes visible within also indicate that NGC 1316 is itself the result of a merger of galaxies in the distant past. Found on the outskirts of the
Fornax galaxy cluster, NGC 1316 is known as Fornax A. One of the visually brightest of the Fornax cluster galaxies it is one of the strongest and
largest radio sources with radio emission extending well beyond this telescopic field-of-view, over several degrees on the sky.
