SPHEREx望远镜绘出102色全天空红外图谱

Core Insights - NASA's SPHEREx space telescope has successfully created the first all-sky infrared map with 102 colors, aiding in the understanding of physical processes post-Big Bang and the evolution of galaxies over nearly 14 billion years [1][2] - The telescope, launched in March, orbits the Earth approximately 14.5 times a day and captures around 3,600 images daily, achieving full-sky coverage after six months of operation [1] - SPHEREx's unique capability lies in its ability to capture a wide range of infrared colors simultaneously, providing detailed information about star and planet formation regions [2] Group 1 - SPHEREx was launched in March and has completed a full-sky survey, producing a panoramic image by December [1] - The telescope operates with six detectors, each equipped with specially designed filters to capture 17 gradient colors, resulting in images composed of 102 different color layers [1] - The combination of wide field of view and multi-color detection distinguishes SPHEREx from other survey projects, such as NASA's Wide-field Infrared Survey Explorer [2] Group 2 - SPHEREx captures infrared light that is not visible to the human eye, providing unique insights into the universe's structure and the distribution of key materials for life within the Milky Way [2] - Previous projects have created all-sky maps, but none have matched SPHEREx's ability to capture such a rich array of colors simultaneously [2] - The telescope's observations will enhance the understanding of cosmic phenomena and the conditions necessary for life [1][2]
