scientists can tell the stars composition and temperature from its spectrum.
Hope tht helps :]
Observation of the shift of a star's spectrum toward red indicates it is moving away from us (redshift), while blue indicates it's moving closer (blueshift). By studying this shift in the star's spectrum, we can determine its velocity and distance from Earth, providing valuable information about its motion and location in space.
The absorption spectrum shows the specific wavelengths of light that are absorbed by a material, indicating the energy levels of electrons in the substance. By analyzing the absorption spectrum, scientists can identify the chemical composition of the material and understand its electronic structure.
Its elemental composition.
Each chemical element has a specific emission or absorption spectrum.
Spectrum gives information about the composition of a star's gases by breaking down the incoming radiation into its constituent wavelengths. This information helps astronomers determine the elements present in the star's atmosphere and its temperature.
The light from stars is used to determine their temperature, composition, distance from Earth, and movement through space. By studying the spectrum of light emitted by stars, astronomers can analyze their properties and gain insights into the nature of the universe.

What makes up the star or element.
What elements the star is made of.
Light is a spectrum. On one end it is red and the other blue. We see light in this spectrum as waves and if it is blue, the object is coming toward us. If the waves are red than it is moving away. The frequency of these waves tell us how fast and object is moving toward or away from us.

how can you tell if an object is reflecting blue light from a star
The differences in spectrum are mainly due to: * Differences in temperature between the stars * Differences in chemical composition * Differences in relative movement (redshift / blueshift, due to the Doppler effect)
Most stars exhibit a continuous spectrum, which contains all wavelengths of light in a continuous distribution. This is often referred to as a blackbody spectrum due to its smooth curve.
Scientists determine a star's temperature by analyzing its spectrum of light. The color and intensity of certain lines in a star's spectrum reveal its temperature. Hotter stars appear blue or white, while cooler stars appear red.
Mainly the temperature, and what elements are in the star's outer layers. Also, using the redshift or blueshift, how fast the star is moving away from us or towards us. For very far-away stars, this can be used to calculate its distance.
