Do atoms emit spectral lines in the nonvisible spectrum?

I'm taking a Stellar Astronomy course, and have a very limited understanding of spectroscopy. 

My basic understanding is that emission lines are the result of electrons needing a very specific amount of energy before they can change orbitals, and when changing orbitals they emit a photon to account for the energy change. This photon results in the emission line, right? 

Assuming I have that understood properly, Here is my question. Do atoms have emission/absorption lines in the radio/infrared/ultraviolet etc. spectra? And if so, could we gain any information by examining these additional spectra? 

Like I said, My understanding is very limited, but I really enjoy this subject and look forward to the answer!

Electronic transitions commonly occur in the UV and visible region. Most materials that aren't colored (i.e. do not absorb visible light) do in fact absorb in the UV region somewhere.

There are other types of transitions that occur in the radio, microwave and IR region, but these are not generally electronic. They include spin magnetic moment, vibrational and rotational transitions.
