The Herschel Space Observatory was a space-based telescope launched by the European Space Agency in 2009. Named after the astronomer William Herschel, the telescope was designed to study the universe in the far-infrared and submillimeter wavelengths. Herschel was equipped with three scientific instruments that allowed it to observe cold and dusty regions in space, including star-forming regions, galaxies, and dusty debris disks around other stars. The observations made by Herschel provided valuable insights into the formation and evolution of galaxies, stars, and planetary systems. The mission ended in 2013, but the data collected by Herschel continues to be studied by astronomers around the world.
