What are some advantages of space telescopes?

• 1. these can observe the electromagnetic spectrum of stars that our atmosphere blocks out

• rays that do enter our atmosphere, just passthrough reflecting/refracting telescopes

• they do not look through earth's atmosphere

• they can observe space any time (not only night)

• they do not have to be connected with only one nation/country
