Seeing the Unseen

Telescopes are powerful tools that let us see distant objects in space. They collect light using lenses or mirrors and can reveal details invisible to the naked eye. There are different types of telescopes—some look at visible light, while others capture radio waves, X-rays, or even infrared.

Types of Telescopes

• Optical telescopes: Use lenses or mirrors to see stars and galaxies in visible light.
• Radio telescopes: Detect radio waves from objects like pulsars and gas clouds.
• Space telescopes: Such as the Hubble Space Telescope, orbit Earth to avoid atmospheric distortion.

Other Tools

Astronomers also use computers for data analysis, spacecraft to travel to other planets, and special detectors for cosmic rays and particles.

Impact of Technology

New tools allow us to discover planets around other stars, analyze the composition of distant galaxies, and even search for signs of life.
