论文摘要
起源太空望远镜（起源）是由国家航空航天局（NASA）选择的四项科学技术定义研究之一，以准备美国2020年的天文学和天体物理学decadal decadal调查。起源将追溯我们起源的历史，从时间灰尘和沉重的元素永久改变宇宙景观到当今的生活。它旨在回答三个主要的科学问题：星系如何形成恒星，制造金属并从电离中发展其中央超级质量的黑洞？在行星形成过程中，如何发展可居住的条件？绕着M型七角星星星旋转的行星会支持生命吗？起源在〜2.8至588μm的中部至远红外波长下运行，由于其冷（〜4.5 K）的孔径和最新的仪器，其敏感性比先前的Far-Ir任务高1000倍。
The Origins Space Telescope (Origins) is one of four science and technology definition studies selected by National Aeronautics and Space Administration (NASA) in preparation of the 2020 Astronomy and Astrophysics Decadal survey in the US. Origins will trace the history of our origins from the time dust and heavy elements permanently altered the cosmic landscape to present-day life. It is designed to answer three major science questions: How do galaxies form stars, make metals, and grow their central supermassive black holes from reionization? How do the conditions for habitability develop during the process of planet formation? Do planets orbiting M-dwarf stars support life? Origins operates at mid- to far-infrared wavelengths from ~2.8 to 588 μm, is more than 1000 times more sensitive than prior far-IR missions due to its cold (~4.5 K) aperture and state-of-the-art instruments.
