The Sun
As the nearest star, the Sun is the brightest radiation source in most frequencies, down to the radio spectrum at 300 MHz (1 m wavelength). When the sun is quiet, the galactic background noise dominates at longer wavelengths. During geomagnetic storms, the sun will dominate even at these low frequencies.

Famous quotes containing the word sun:
“In the pink light
the small red sun goes rolling, rolling,
round and round and round at the same height
in perpetual sunset,”

And hoarse with having little else to do,
Excepting to wind up the sun and moon
Or curb a runaway young star or two.”
