NASA has four "Great Observatories" in orbit, looking at different parts of the electromagnetic spectrum:-
Hubble for ultra-violet to near infra-red
Compton Gamma-Ray Observatory for gamma-rays
Chandra X-Ray Observatory for X-rays
Spitzer Space Telescope for infra-red
There are a number of orbiting radio telescopes, including the Very Long Baseline Interferometry satellites.
