irregular, spiral and elliptical are all different shapes of galaxies which are used to classify them
true or false
True
True. Irregular, spiral, and elliptical are indeed different shapes of galaxies that are used to classify them.
True.
When classifying galaxies, irregular, spiral, and elliptical are three main shape categories used. Here's a brief explanation of each:
1. Irregular galaxies: These galaxies lack a defined shape, appearing disordered and chaotic. They often have a high concentration of gas and dust, and exhibit intense star formation activity.
2. Spiral galaxies: These galaxies have a distinct spiral structure, with arms that wrap around a central bulge. The arms are made up of young stars, gas, and dust, while the bulge contains older stars. Our Milky Way is a spiral galaxy.
3. Elliptical galaxies: These galaxies are more spherical or elongated in shape, lacking the spiral arms characteristic of spiral galaxies. They contain mainly older stars and have less active star formation compared to irregular and spiral galaxies.
In summary, irregular, spiral, and elliptical galaxies are different shapes used in the classification of galaxies.
