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:
“So we saunter toward the Holy Land, till one day the sun shall shine more brightly than ever he has done, shall perchance shine into our minds and hearts, and light up our whole lives with a great awakening light, as warm and serene and golden as on a bankside in autumn.”
—Henry David Thoreau (1817–1862)
“If I could only live at the pitch that is near madness
When everything is as it was in my childhood
Violent, vivid, and of infinite possibility:
That the sun and the moon broke over my head.”
—Richard Eberhart (b. 1904)
