Sentences with phrase «invisible infrared wavelengths»

Red dwarf stars, which only have some 10 to 50 percent of the Sun's mass but comprise perhaps 85 percent our Milky Way galaxy's stars, radiate most strongly at invisible infrared wavelengths and produce little blue light.

Earth receives energy that travels from the sun in a variety of wavelengths, some of which we see as sunlight and others that are invisible to the naked eye, such as shorter - wavelength ultraviolet radiation and longer - wavelength infrared radiation.
