What are some advantages and disadvantages for using an ultraviolet telescope? Why is at better/easier or harder to use a UV telescope than another telescope like a radio telescope or an infrared telescope?
Radio telescopes can be used on earth's surface. But all infra red rays does not reach earth's surface.
So we have to send them to earth orbit above our atmosphere which filters radiations.Certain objects emit only radiation in UV range.So to study them we have to use UV ray telescopes.
