The light from many stars can be seen from Earth. But there is a time delay between the time the light is emitted from the star and when we see it here on Earth. Which of the following statements best explains why there is a delay?

• Stars twinkle, so they give off light at regular intervals.

• The stars’ light is not bright enough to reach Earth immediately.

• Stars are light-years away from Earth, so light takes time to reach our planet.

• Earth’s atmosphere is too thick for light to reach the surface as soon as it is emitted.
