significance of satellites for our understanding of the universe?

Question

and any examples? thank you so much

Answer 1

The Earth's atmosphere blocks many types of radiation, including infrared and X-rays.

By using "space telescope" on a satellite above the atmosphere these radiations can be seen and studied.

Infrared and X-ray (and other) wavelengths bring new/different information about what is happening in

the universe.

See the article:

and, for example, the cool X-ray images from Chandra:
