The Hubble Space Telescope is a well-known satellite. It was launched into space in 1990. It is in orbit 380 miles above Earth. Hubble takes photos of our solar system and faraway galaxies. A galaxy is a huge group of stars, dust, and gas. Over the years, Hubble has taught scientists a lot about space. What is the appropriate unit for measuring the distance to other galaxies?

• Miles

• Kilometers

• Light Year

• Astronomical Unit

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.
