Select the correct text in the passage.
Which sentence explains why optical land telescopes are not able to take images as clear as those taken by the Hubble Space Telescope?
Hubble and land telescopes take pictures of planets, stars, and galaxies. The mixture of gases that surround a planet is called its atmosphere. Earth’s atmosphere changes and blocks some of the light that comes from space.
Hubble needs to be updated.
So, Hubble can see space more clearly than telescopes on Earth can. Hubble is not the kind of telescope that you look through with your eye. Hubble uses a digital camera to take pictures. Then, Hubble uses radio waves to send the pictures through the air back to Earth.
Earth’s atmosphere changes and blocks some of the light that comes from space.
The sentence that explains why optical land telescopes are not able to take images as clear as those taken by the Hubble Space Telescope is:
"Earth’s atmosphere changes and blocks some of the light that comes from space."
