A joint project between the space agencies of America, Canada and Europe, the JWST provides astronomers with the most powerful tool yet to scan the cosmos in infrared frequencies, picking up the most distant objects. Given that, to astronomers, “distant” also means “longer ago” in cosmic terms, the telescope will be able to spot signs of the cosmic dawn—the moment when the universe’s first stars ignited. 翻译与注解： （注：内容为机翻，仅供学习参考） On the ground it was delayed, over budget and at risk of being axed.
