• TRUE

• FALSE

​III. Other galaxies are so far away that they cannot easily be seen without a telescope.

• Telescopes make faraway objects look larger. Some galaxies can be seen using small backyard telescopes.

​V. Galaxies are clouds made up of gas, dust, stars, and any objects that orbit the stars.

• Each star that has objects such as planets, moons, asteroids and comets orbiting it is a solar system.

  • There are many billions of stars in each galaxy, and there are many billions of galaxies in the entire universe.
