Telescopes: Tools for Seeing

Telescopes magnify distant celestial objects for observation.

The Hubble Space Telescope has captured stunning images of distant galaxies, such as the Whirlpool Galaxy, which is over 30 million light-years away. This is possible because telescopes can magnify distant celestial objects, allowing us to observe them in greater detail.

The magnification power of a telescope depends on its lens or mirror size and quality.

By using telescopes, astronomers can study the universe in greater detail, from the surface of the Moon to the farthest reaches of the cosmos.
