This image is a spectrometer, because it divides the light into the visible colors of the spectrum: Red, Orange, Yellow, Green, Blue, Indigo, and Violet.

This Nasa website helped me understand the basics of spectroscopy. It is the study of the electromagnetic spectrum, the elements galaxies and other space formations are made of, and much more. The basic tool in spectroscopy if the spectrometer that measure emission lines.

Astronomy - spectroscopy - 3/3

Spectroscopy is the study of energy and matter, the dispersion of light, and measurement of wavelength. This video contains useful information that helped me understand spectroscopy.

This diagram shows the basics of spectroscopy, in which a receding star's wavelengths aren't compressed as much, so it reverts to the red end of the spectrum. Vice versa for an approaching star.

Ideas

I think we could combine both Abby's and Kay's ideas into one: learning how chemical reactions in space and chemical reactions on Earth are the same/different.
I personally want to learn about what happens when two galaxies collide.

I want to learn more about biology and cells. I would like to do more video projects and group projects.

I would like to learn more about chemistry, and chemical reactions. I think it's really interesting.
