Science Behind the Discoveries
Indulge your curiosity and dive into the fundamental science that is the foundation of Hubble’s observations. Discover how Hubble uses different wavelengths of light to reveal much more information than the human eye can see, then explore the individual components of that light as you learn about spectroscopy. Finally, learn how these pieces are brought together to create Hubble’s iconic images.

In a Different Light
Learn how Hubble uses different wavelengths of light to explore the universe.
Human eyes are sensitive to a small portion of available light called the visible spectrum. Hubble sees that visible light as well, but it also goes beyond visible wavelengths and delves into the infrared and ultraviolet parts of the spectrum. Learn how Hubble uses those different wavelengths of light to explore the universe.
