HII/L2 Mission: a New Space Telescope for Mid- and Far-Infrared Astronomy

摘要

We present the concept of the HII/L2 (or SPICA) mission, which incorporates a 3.5 m telescope cooled to 4.5 K. HII/L2 will Focus on high-resolution mid- to far-infrared observations with unprecedented sensitivity. It will make great contributions to our understanding of basic astronomical questions, such as the history of star-formation in the universe, the birth and evolution of AGN, the formation of planets in extrasolar systems, and the history of our solar system.
