Exploring Color and Wavelengths in Space

Exploring Color and Wavelengths in Space | Science Fair Projects | STEM Projects
This project delves into how the electromagnetic spectrum and wavelength are related to the colors we perceive in space. By examining the colors of stars, nebulae, and galaxies, we can gain insights into the workings of the cosmos.


The hypothesis is that the color of celestial objects is related to their temperature and composition.

Method & Materials

You will study the properties of light, the electromagnetic spectrum, and how it relates to color. Using images and data from telescopes, you will analyze the colors of stars, nebulae, and galaxies, and compare their temperature and composition.
You will need a computer with internet access, access to image and data archives from telescopes (such as the Hubble Space Telescope), a color wheel, and a notebook.


By analyzing the colors of celestial objects, scientists can learn about their temperature, composition, and motion. This project shows that color is more than just a visual experience, but an important tool for understanding the universe. An observation that stands out is the discovery of "forbidden" colors in space, which are colors that are not found on Earth and are only visible in the vacuum of space.

Why do this project?

This science project is interesting because it combines art and science to reveal the beauty and complexity of the universe. It also shows how color can be used as a tool for scientific inquiry, and how it can reveal information that is invisible to the naked eye.

Also Consider

Experiment variations to consider include analyzing the colors of different types of celestial objects (such as black holes or pulsars), or exploring the effects of different filters on the colors of objects.
