Question

Quizplus · Accepted Answer

Telescopes planned for studying the earliest stages in galactic lives will be optimized for observing in infrared light. This is because infrared light can penetrate clouds of gas and dust, which allows for observations of star formation and other early stages of galaxies that are not possible in visible light. Radio waves and X-rays are also used in studying galaxies, but they are not the main wavelengths used for observing the earliest stages.
