* To see beyond the Earth's atmosphere: Our planet's atmosphere acts like a blurry lens, absorbing and scattering light from space. This makes it difficult to see faint objects and certain wavelengths of light. Space telescopes are above the atmosphere, allowing them to capture clearer and more detailed images.

* To study the universe in different wavelengths: Earth's atmosphere blocks many wavelengths of light, including infrared, ultraviolet, and X-rays. Space telescopes can observe these wavelengths, revealing information about the universe that ground-based telescopes can't.

* To observe objects that are too faint for ground-based telescopes: Space telescopes have the advantage of being far from city lights and other sources of light pollution. This allows them to observe very faint objects, such as distant galaxies and stars.

In summary, space telescopes were invented to overcome the limitations of ground-based telescopes and to expand our understanding of the universe by studying objects and phenomena that are invisible from Earth.
