Answer 2

Final answer:

A galaxy is a vast collection of stars, solar systems, gas, and dust.

Four important features of the Milky Way Galaxy are:

1. The nucleus
2. A central bulge
3. A massive halo
4. Spiral arms

Explanation:

• Galaxies are enormous collections of stars, gas, dust, and dark matter that are held together by gravity, much like our solar system is held together by gravity.

• Galaxies are found all around the cosmos, either alone or in groups. Like everything else, galaxies are created, develop, and eventually perish. Galaxies can slam against one another or drift away. There may be trillions of stars in each galaxy, each with its own solar system.

• There are thought to be a few hundred billion galaxies in our observable universe, while the exact number is unknown. This implies that there are more stars in the universe than there are sand grains on Earth as a whole.

• A galaxy is made up of four basic parts: the disc, which may contain spiral arms, the halo, the central bulge, and the black hole at its center. The spherical component is the collective name for the halo and the central bulge.
