Galaxies can be grouped by the age of the stars they tend to contain, with spiral galaxies having the youngest stars and elliptical galaxies having the oldest stars.
To answer this question, we need to understand the characteristics of each type of galaxy.
- Spiral galaxies are characterized by their spiral arms and a central bulge. They typically have a mix of young and old stars, as well as interstellar gas and dust.
- Elliptical galaxies are mostly made up of older stars and have a smooth, ellipsoidal shape. They don't have much interstellar gas or dust and do not typically form new stars.
- Irregular galaxies, as the name suggests, don't have a regular shape. They can contain both young and old stars and may have ongoing star formation.
Now, based on this information, we can determine the answer to the question. Which type of galaxy tends to have the youngest stars? And which type tends to have the oldest stars? Once we have those answers, we can drag and drop the words into the correct locations in the question.
