All galaxies have a dense core of stars. Spiral galaxies, however, have arms that are often visible. There are two kinds of spiral galaxies: barred, where there appears to be a line running from arm to arm through the core, and ordinary, where there is no bar.
the spiral galaxy is very bright because of its stars, that's why our galaxy is called the milky way because it looks milky and our galaxy(the milky way) is located in one of the arms of a spiral galaxy!
When billion of stars are in a concentrated dense cloud it is called a galaxy.

we live in a barred spiral galaxy on the end of a spiral arm called the milky way.It's name comes from the ancient idea that the wavy line of stars of our spiral arm looked like spilt milk. 'Lactic'
An ordinary spiral galaxy has spiral arms coming out of the core. In a barred galaxy, the central area consists of a bar of stars and the spiral arms are attached to the ends of the bar.
