Answer:
The most widely recognized sort of cosmic system is known as a ""spiral galaxy.""
As anyone might expect, spiral galaxy look like spirals, with long arms twisting toward a bright lump at the inside.
Some spiral systems have arms that are twisted firmly, while different cosmic systems have all around freely twisted arms.
The firmly and freely twisted spirals is one of the ways with which you can identify the difference between different galaxies.
Some spiral galaxy have a fine line, or bar, going through them.
These are classified ""barred spiral galaxies.""
