NGC 1365
Encyclopedia
NGC 1365, also known as the Great Barred Spiral Galaxy, is a barred spiral galaxy
about 56 million
light-year
s away in the constellation
Fornax
.
The core is an oval shape with an apparent size of about 50″ × 40″.
The spiral arms extend in a curve north and south from the ends of the east-west bar and form an almost ring like
Z-shaped halo.
Supernova
e 2001du, 1983V, and 1957C were observed in NGC 1365.
Due to recent revisions in the consensus opinion on the shape of our own galaxy, it seems likely that the Milky Way
strongly resembles NGC 1365.

Ring galaxy
A ring galaxy is a galaxy with a ring-like appearance. The ring consists of massive, relatively young blue stars, which are extremely bright. The central region contains relatively little luminous matter. Some astronomers believe that ring galaxies are formed when a smaller galaxy passes through...

Supernova
Supernova
A supernova is a stellar explosion that is more energetic than a nova. It is pronounced with the plural supernovae or supernovas. Supernovae are extremely luminous and cause a burst of radiation that often briefly outshines an entire galaxy, before fading from view over several weeks or months...
