Ever wonder what’s beyond the rainbow? IRAS knows. The Infrared Astronomical Satellite can look into the invisible range of light known as the infrared and view regions of the sky once hidden from sight. Infrared, the heat radiated by objects, can expose objects even in total darkness. This new window on the universe allows us to view comets, stars and galaxies in a way that helps scientists and astronomers piece together celestial mysteries.

NOVA lets you share in the history-making space discoveries. Breathtaking footage reveals new planetary systems, comets, colliding galaxies, the birth of stars and vast clouds of interstellar space dust. Join the search beyond the rainbow and explore all the fascinating secrets the heavens hold.
