spiral galaxy

Beautiful Barred Spiral Galaxy NGC 1300.



 
This Hubble Space Telescope image shows a spiral within a spiral: the nucleus of this spiral galaxy has its own extraordinary and distinct, 'grand-design' spiral structure that is about 3,300 light-years long. Only galaxies with large-scale bars appear to have these grand-design inner disks. Unlike other spiral galaxies, NGC 1300 is not presently known to have a massive central black hole.
NGC 1300 is located about 61 million light-years away in the direction of the Eridanus constellation. Its total length is about 110,000 light-years.
