Spectroscopy is a powerful tool for astronomers. Analysis of the spectral signatures of astronomical objects may reveal information about the temperature, density, composition, and other important details. This information can help us answer questions like: What is this object? What is it made of? How far away is it?

Astra presents the spectroscopy app that illustrates the science of spectroscopy through images of " The Milky Way " by modern science. Learn about spectroscopy using Astra's Spectroscopy App here. Find out how the Milky Way galaxy appears as various light wavelengths - - x-ray, gamma, ultraviolet, visual, infrared, microwave, and radio.
