NASA's space telescopes also give us a way to look back in time Telescopes help us see stars and galaxies that are very far away. It takes a long time for the light from faraway galaxies to reach us So, when we look into the sky with a telescope, we are seeing what those stars and galaxies looked like a very long time.
