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.
Light goes incredibly fast through space, bouncing off objects.
Objects in space that can only be viewed from earth becouse of reflected light energy are said to be
Stars
so you can group the objects into certain categories.
objects in space that can only be viewed from earth because of reflected light energy are said to be luminous.
Stars, galaxies, nebulae, and other luminous celestial objects emit light in space. These objects emit different wavelengths and intensities of light based on their composition and physical characteristics.
Light
The only objects in space that emit their own light are stars, including our Sun. They generate light through nuclear fusion in their cores, converting hydrogen into helium and releasing energy in the form of light and heat. Other celestial objects, like planets and moons, do not emit light but reflect the light from stars.
Stars are the only objects in space that give off their own light.Other objects are visible only if a star shines on them.
