radio astronomy

(astronomy observation and analysis of radio EMR)

Radio astronomy is the branch of astronomy dealing with the observation and analysis radio waves from astronomical sources. Radio offers somewhat independent information from sources, and the frequency range includes atmospheric windows, offering observation not readily available across electromagnetic radiation, and adapts easily to interferometry such as very-long-baseline interferometry (including Earth-sized VLBI) which gives it a very high angular resolution.

Organizations dedicated to radio astronomy include:

Some terms used for divisions of radio astronomy (by wavelength):
