Visible Light and Beyond “White light” is made up of a rainbow of colors, each with a different wavelength.
The Electromagnetic Spectrum Our eyes see only part of the electromagnetic spectrum…
Each part of the spectrum impacts our daily lives… “Invisible” Light in Society Microwave ovens Communications Remote controls X-rays UV Sunscreen
NASA SMD Astrophysics: Discover the origin, structure, evolution, and destiny of the universe, and search for Earth-like planets
We collect light from distant objects, and bring together researchers from many disciplines. The Tools of Our Search
