Light is used for a number of purposes, the most basic being sight. When light hits something it deflects off of the object and when you look at the object the light that transfers into your eye creates the image before you. If there is little or no light, it becomes harder to see images and color.
Another use for light would be warmth. Sunlight, for example, warms the earth and keeps us from freezing. Without the sun we would be done. Excuse my pun. You notice how the temperature drops at night a few degrees? Well that's because we are blocked from the warm light that the sun emits.
Plants have other uses for light. They can literally take a sunbeam and turn it into food in a process called photosynthesis. In any case, Light has many uses.
Objects that emit light are usually referred to as incandescent.
Some examples of objects that emit or reflect infrared light include the sun, humans, animals, and electronic devices such as remote controls and infrared cameras.
By definition, something which does not emit light cannotbe seen. However, it can be observed, in that its effects such as through gravity and electromagnetism can be detected.
Some light sources can emit multiple types of light, such as white light sources that emit a combination of different colors.
Some examples of objects that emit infrared waves include humans, animals, hot objects like stoves or heaters, and electronic devices such as remote controls.

Objects in space that produce their own light are known as luminous objects. Some examples include stars, such as our Sun, which emit light through the process of nuclear fusion, and hot planets like Jupiter, which reflect and emit light due to their internal heat. Other examples include galaxies, supernovae, and nebulae that emit light due to various astronomical processes.
Radio Telescope observe light of a different wavelength then optical light. Radio waves have a longer wavelength then visible light. Some interstellar objects barley emit any light in the visible spectrum but emit a significant amount of radiation in the radio spectrum. Radio telescopes enable us to view objects which emit in the radio spectrum.
Black holes and neutron stars are examples of stars that do not emit visible light. They can only be detected by their gravitational effects on nearby objects or through other forms of radiation such as X-rays or radio waves.

The primary source of light for objects in space is usually stars, which emit light and other forms of electromagnetic radiation through nuclear fusion in their cores. Some objects in space can also reflect light from nearby stars or other sources, contributing to their overall brightness.
Objects that reflect light include planets, asteroids, and comets. The Sun emits light as it is a star. Meteors are visible as they burn up in the Earth's atmosphere, reflecting some light. Stars emit their own light through fusion reactions.
Objects that emit infrared light include hot objects and bodies that are giving off heat, such as the Sun, fires, and heated objects like stovetops. Additionally, some electronic devices like remote controls and night vision cameras emit infrared light as part of their functionality.
Luminous objects are those that emit their own light. Examples of such objects include the following; the sun, lightened candle, stars, torch bulb and Hydrogen atoms.A luminous object is an object that gives off light. Here are some examples; A light bulb, torch, match, sun, lit candle.
