To astrophysicists studying the universe, infrared sources such as planets are relatively cool compared to the energy emitted from hot stars and other celestial objects. Earth scientists study infrared as the thermal emission (or heat) from our planet. As incident solar radiation hits Earth, some of this energy is absorbed by the atmosphere and the surface, thereby warming the planet. This heat is emitted from Earth in the form of infrared radiation. Instruments onboard Earth observing satellites can sense this emitted infrared radiation and use the resulting measurements to study changes in land and sea surface temperatures.

The global image on the right is an infrared image of the Earth taken by the GOES 6 satellite in 1986. A scientist used temperatures to determine which parts of the image were from clouds and which were land and sea. Based on these temperature differences, he colored each separately using 256 colors, giving the image a realistic appearance.

We can sense some infrared energy as heat. Some objects are so hot they also emit visible light—such as a fire does. Other objects, such as humans, are not as hot and only emit only infrared waves. Our eyes cannot see these infrared waves but instruments that can sense infrared energy—such as night-vision goggles or infrared cameras–allow us to "see" the infrared waves emitting from warm objects such as humans and animals. The temperatures for the images below are in degrees Fahrenheit.

Fresnel lights are specialized lighting fixtures, named after French physicist Augustin-Jean Fresnel. At its heart lies the Fresnel lens, characterized by its unique concentric circle design. This lens efficiently focuses light output, producing a sharp yet soft beam.

Color temperature, on the other hand, determines the warmth or coolness of the light. Fresnel lights typically range from 3,200K (warm, tungsten light) to 5,600K (daylight). Some modern Fresnel lights, especially LED variants, offer adjustable color temperatures, allowing users to dial in the appropriate mood for their shots.

Unlike standard production lighting, Fresnels offer adjustable focus, allowing a seamless transition from spotlight to floodlight. This is generally achieved by moving the lamp closer to, or further from, the lens. This combination of adjustable focus and soft light quality sets Fresnel lights apart from other fixtures.

Why use the infrared to image the Earth? While it is easier to distinguish clouds from land in the visible range, there is more detail in the clouds in the infrared. This is great for studying cloud structure. For instance, note that darker clouds are warmer, while lighter clouds are cooler. Southeast of the Galapagos, just west of the coast of South America, there is a place where you can distinctly see multiple layers of clouds, with the warmer clouds at lower altitudes, closer to the ocean that's warming them.

Many objects in the universe are too cool and faint to be detected in visible light but can be detected in the infrared. Scientists are beginning to unlock the mysteries of cooler objects across the universe such as planets, cool stars, nebulae, and many more, by studying the infrared waves they emit.
