    What is Jansky in radio astronomy?The jansky (symbol Jy, plural janskys) is a non- SI unit of spectral flux density, [1] or spectral irradiance, used especially in radio astronomy. It is equivalent to 10 −26 watts per square metre per hertz . The flux density or monochromatic flux, S, of a source is the integral of the spectral radiance, B, over the source solid angle :
