Its neighbor galaxy NGC 1316 has a more sordid past: It's a cannibal.
2-meter telescope at La Silla Observatory in Chile, dark dust lanes and twisting tails betray a history of galactic collisions that have built NGC 1316 into the monster it is today.
With each collision, gas and dust feed a supermassive black hole in the core of NGC 1316 that weighs about as much as 150 million suns.
NGC 1316 is slightly elongated in a north-east to south-west direction.

Two appeared in NGC 1316, a galaxy better known as Fornax A, a strong radio galaxy near the centre of the Fornax cluster.
Large galaxies usually have no more than three supernovas blow up in a century, but the nearby galaxy NGC 1316 has had two such explosions within the past 5 months and four in the past 26 years.
The team confirmed that like the earlier two NGC 1316 supernovas, the most recent ones belong to the class called type la.
