Herschel refers to the European Space Agency's Herschel Space Observatory, a large infrared telescope launched in 2009. The Herschel Space Observatory was designed to study the universe in the far-infrared and submillimeter wavelengths, allowing astronomers to observe cool and dusty regions in space where stars and galaxies form. Herschel has made significant contributions to our understanding of star formation, galaxy evolution, and the presence of water and organic molecules in space.
