🔴Discover the advantages of using infrared light to study exoplanets.
What is a coronagraph?
—A coronagraph is a device used to block the light from a star so that astronomers can observe faint objects near the star, such as exoplanets.
Can I create my own coronagraph demonstration at home?
—Yes, you can easily create a coronagraph demonstration at home with simple materials like a science display board, light sources, and a template for the coronagraph.
What can I learn from this DIY science project?
—Through this DIY science project, you can learn about the concept of space, the properties of different types of light, and how scientists study exoplanets.
Why is it important to study exoplanets?
—Studying exoplanets helps scientists understand more about the formation of planets and the possibility of life outside of our solar system.
What are diffraction glasses used for?
—Diffraction glasses are used to separate white light into its component colors, allowing you to see the spectrum and understand the different temperatures and colors of stars.
