Not exact matches

Inside the greenhouse the visible light is absorbed by the plants and soil and is converted into heat, which is then emitted by the plants and soil in form of infrared radiation.

Early in their lives, the radiation they emitted was largely blocked by the thick veil of their host nebula, visible only to telescopes at infrared and radio wavelengths.

The visible solar radiation mostly heats the surface, not the atmosphere, whereas most of the infrared radiation escaping to space is emitted from the upper atmosphere, not the surface.

In 2009, the Spitzer Space Telescope discovered infrared radiation from a ring far beyond all the others encircling Saturn; sunlight heats the ring's dust, which emits its heat at infrared wavelengths.

The material is transparent to the visible sunlight that powers solar cells, but captures and emits thermal radiation, or heat, from infrared rays.

They found that HD 98800, which is an orange star, emits 10 per cent of its radiation in the far - infrared — at wavelengths between 10 and 100 micrometres.

Because LEDs do not emit heat as infrared radiation like incandescent or fluorescent bulbs do, it must be removed from the device by conduction or convection.

Webb's giant sunshield will protect it from stray heat and light, while its large mirror enables it to effectively capture infrared light, bringing us the clearest picture ever of space objects that emit this invisible radiation beyond the red end of the visible spectrum — early galaxies, infant stars, clouds of gas and dust, and much more.

While optical instruments can detect the dust when it obscures more distant objects or when it is illuminated by very nearby stars, infrared telescopes are able to register the long - wavelength radiation that the cool dust clouds themselves emit.

Direct imaging can be done by using starlight reflected off the planet or thermal infrared radiation emitted by the planet.
