NGC 1300 is a barred spiral galaxy in the constellation of Eridanus. It is about 61 million light-years away from Earth. It has around 110,000 light-years of diameter, about the same size of the Milky Way galaxy. It is a member of a galaxy cluster, the Eridanus Cluster, consisting of at least 200 galaxies.
Center[change | change source]
The core of larger spiral arms of NGC 1300, the nucleus shows another inner grand-design spiral structure that is about 3,300 light-years long. These cases are rare, since it requires a galaxy with a large galaxy bars, to have the inner spiral. In a nutshell, the nucleus basically has another spiral arms in it, which makes it — a spiral in another spiral. Some models suggested that the arms can be pulled inwards, shaping a spiral into the nucleus, which may be pulled by the extreme gravity of a supermassive black hole at the very center of the galaxy.
NGC 1300 is not known to have an active nucleus, indicating it is not a quasar, nor accreting matter.
