The spectra of the stars you want to analyze.
Forensic scientists can use emission line spectra and absorption spectra to analyze trace evidence, such as glass fragments or paint chips, found at a crime scene. By comparing the spectra of the collected samples with reference spectra, scientists can identify the chemical composition of the evidence and link it to potential sources or suspects.
Spectra are produced by interaction of electromagnetic radiation with matter, typically atoms or molecules. The particle responsible for spectra is the photon, which carries energy and interacts with electrons in the atoms or molecules to produce the spectral lines observed in both emission and absorption spectra.
A full moon often appears yellow when it's low in the sky due to the scattering of light. As moonlight passes through more of the Earth's atmosphere, shorter blue wavelengths scatter out, leaving the longer red and yellow wavelengths. This phenomenon is similar to why the sun looks yellow or orange at sunrise and sunset. Additionally, atmospheric conditions such as dust and pollution can enhance this effect.
Each substance has known specific maximum of absorption. Comparing spectra substances can be identified.

During a sunset, the sky appears yellow because of the way sunlight is scattered by particles in the Earth's atmosphere. The shorter blue and green wavelengths are scattered away, leaving the longer red and yellow wavelengths to dominate the sky's color.
The order of colors typically seen in a sunset are red, orange, yellow, and sometimes pink or purple.
During a sunset, the sky turns yellow because of the way sunlight is scattered by particles in the Earth's atmosphere. The shorter blue and green wavelengths are scattered away, leaving the longer red and yellow wavelengths to dominate the sky's color.
E110 is Sunset Yellow which is certifiable as FD&C Yellow #6. E904 is shellac. See Related Links.
sunsets are red/yellow/orange because of ultriaviolents and invisible rays. it can also be caused by radiation.
The horizon seems pale yellow during sunset and sunrise because the sunlight refracts through the atmosphere, only allowing colors like reds and yellows to show through.
During a sunset, the sky appears yellow because of the way sunlight is scattered by particles and gases in the Earth's atmosphere. This scattering causes shorter blue and green wavelengths of light to be dispersed, leaving longer red and yellow wavelengths to dominate the sky's color.
