Later observations revealed that NGC 4945 has an active nucleus, which means that its central bulge emits much more energy than quieter galaxies, such as the Milky Way. Later observations showed that NGC 4945 has an active nucleus, which means that its central bulge emits much more energy than quieter galaxies, such as the Milky Way. NGC 4945 is a barred spiral galaxy in the constellation Centaurus, visible near the star Xi Centauri. Apart from these similarities, NGC 4945 has a brighter centre that is likely to host a supermassive black hole that gobbles up vast amounts of matter and spews energy out into space.
Other observations have shown that NGC 4945 has an active galactic core, meaning its central bulge radiates far more energy than quieter galaxies like the Milky Way. Scientists classify NGC 4945 as a Seyfert galaxy. Astronomers have since suspected that a supermassive black hole is causing the intense motion in the centre.
