Astronomers make observations in visible light, but also in other parts of the electromagnetic spectrum, such as radio and gamma waves. Scientists make observations in different wavelengths because -
other wavelengths can enter Earth's atmosphere undisturbed.
observations in different wavelengths provide different information about stars.
the information provided by visible light is not a reliable source of data.
visible light only provides information about the closest objects in our galaxy.
