Answer:
chemical composition
Explanation:
The spectral data not only provides information about the chemical composition of the objects in space, but also their type, surroundings, and the kind of motion they exhibit.
Natural targets typically receive both direct solar flux from the sun and scattered skylight, which can be used to determine the elements in a sample because they reflect light differently, to measure the distance and speed of galaxies
What is spectrocopy?
The study of how matter absorbs and emits light and other types of radiation is known as spectroscopy. In a manner similar to how a prism divides light into a rainbow of colors, it involves splitting light (or more accurately electromagnetic radiation) into its individual wavelengths (a spectrum).
Generally, under sunlight, field spectroscopy is a technique used to assess the reflectance characteristics of vegetation, soils, rocks, and water bodies in the natural environment. Measurement of light reflected off of natural environment objects is of interest to some disciplines.
Natural targets typically receive both direct solar flux from the sun and scattered skylight, which can be used to determine the elements in a sample because they reflect light differently, to measure the distance and speed of galaxies,
Thus, spectroscopy can provide information about the outer space
