Herschel Will Deliver Data from Outer Space
Herschel, the largest infrared telescope ever launched, is designed to study some of the coldest objects in space, located deep in a region of the electromagnetic spectrum that is still largely unexplored.
Its massive one-piece mirror, which is almost one-and-a-half times larger than Hubble’s, is delivering sharper images of the stars with coverage of a wider wavelength spectrum. This new data is providing astronomers with a better understanding of the composition, temperature, density and mass of interstellar gas and dust — the fuel for star formation — in nearby galaxies and star-forming clouds.
