About this Image
NGC 4945 is a barred nearly edge-on spiral galaxy in the constellation Centaurus.
It is thought to be quite similar to the Milky Way Galaxy, but X-ray observations show that NGC 4945 has an unusual, energetic, Seyfert 2 nucleus that might house a large black hole.
It was discovered by James Dunlop in 1826.
