kierteisgalaksi
Kierteisgalaksi, also known as a spiral galaxy, is a type of galaxy characterized by its flattened, spinning disk that contains a central bulge and spiral arms. These arms are regions of active star formation, appearing brighter due to the presence of young, hot, blue stars and glowing nebulae. The central bulge is typically an older, more spherical concentration of stars, often containing a supermassive black hole at its core.
The structure of a spiral galaxy is maintained by a complex interplay of gravity and rotation. The
Our own Milky Way galaxy is a prime example of a spiral galaxy. Other well-known spiral galaxies
