Space Telescopes

What Is a Telescope?

A telescope is a special tube that helps us see far away things. It makes tiny, dim objects look bigger and brighter. On Earth we use telescopes to look at stars, but some telescopes go up into space.

Why Put Telescopes in Space?

The sky above us is full of air and clouds. They can blur the view of stars. A space telescope floats above the air, so it gets a crystal‑clear picture. It can also see colors of light that our eyes cannot see.

Famous Space Telescopes

• Hubble: Looks at galaxies, nebulae, and planets. It has taken many beautiful pictures that people love.
• James Webb: Is very big and can see the oldest light in the universe. It helps scientists learn how stars and planets form.
• Spitzer: Looks at heat from far‑away objects, showing us hidden stars inside dusty clouds.

Space telescopes let us explore the universe without leaving Earth. They help us answer big questions like “How did the Sun form?” and “Are there other worlds like ours?” By looking up with these amazing tools, we learn more about the amazing space around us.
