On the left is an image of Jupiter taken in visible light, and it shows Jupiter how you would see it in a dark sky.

However, when viewed with light of 6 cm wavelength (on the right), Jupiter appears much larger! We call wavelengths of light in the centimeter range or longer RADIO LIGHT. Light at 6 cm shows us the structure of the magnetic field around Jupiter; in fact, if our eyes were sensitive to this wavelength of light, Jupiter would appear to be almost times larger than the full moon!!
