Identifying star elements in space

By: Michael, Matt, and Collin


Astronomers use a spectroscope, which is an instrument used to measure properties of light over a specific portion of the electromagnetic spectrum. Anyone can use a spectroscope to identify what elements are in stars.

Identifying the star elements

Astronomers use this spectroscope by passing star light through it to separate the light into a spectrum. The spectrum is a rainbow of different colors. Each element on the periodic table gives a different pattern of colors. The astronomers analyze the color patterns to tell which elements are in each star.
