Answer 1

It looks like you're comparing three different types of galaxy shapes—elliptical, irregular, and spiral. Here’s a summary of the characteristics associated with each shape:

1. **Elliptical Galaxies:**
- **Shape:** Long, oval shape
- **Stars:** Contains older stars
- **Brightness:** Generally does not shine brightly
- **Structure:** Central disk is typically absent

2. **Spiral Galaxies:**
- **Shape:** Central disk with radiating arms
- **Stars:** Mix of old and young stars
- **Brightness:** Shines brightly due to the presence of young stars
- **Structure:** Well-defined structure with spiral arms

3. **Irregular Galaxies:**
- **Shape:** Undefined shape
- **Stars:** Mix of old and new stars
- **Brightness:** Can vary, but they often do not have a structured appearance like spiral or elliptical galaxies

Your answer aligns with these descriptions. If you need more information or further clarification, just let me know!
