How Telescopes Work

Science · Space Exploration · conceptual

Know that telescopes are instruments that help us see distant objects in space, and that space telescopes like Hubble and James Webb orbit above Earth’s atmosphere to get clearer views of the universe

Sign in to track this

What mastery looks like

  • Explain that a telescope magnifies distant objects so we can see them in more detail
  • State that Earth's atmosphere blurs the view, so space telescopes get clearer pictures
  • Name at least one space telescope (Hubble or James Webb) and describe what it does

Check your understanding

Does How Telescopes Work know what a telescope does and why some telescopes are sent into space — like the Hubble or James Webb telescopes?
