Star forming gas clouds in our galaxy, called HII regions (pronounced "H-two") emit radio waves over a broad range of frequencies.   But, HII regions emit more radio waves at higher frequencies.

Experiment:

Design an experiment using the Quiet Skies Detector that will inform your team about RFI in the frequency range of 1450-1700 MHz in your area.
