第1896期:NASA’s James Webb Celebrates One Year of Science Discoveries

Episode 690 Published 2 years, 7 months ago
Description

The James Webb Space Telescope recently celebrated its first year in operation. During that time, the orbiting observatory – operated by the American space agency NASA – produced colorful, detailed images. It has also helped researchers make several new scientific discoveries. NASA has described the telescope as the largest, most powerful telescope ever sent into space. The agency launched the Webb in late 2021 and released its first images in July 2022. The Webb’s first full-color images were presented by President Joe Biden. One of the images showed the clearest picture yet of the early universe, about 13 billion years ago.

詹姆斯·韦伯太空望远镜最近庆祝了其运行一周年。 在此期间,由美国宇航局运营的轨道天文台产生了色彩丰富、细节丰富的图像。 它还帮助研究人员取得了几项新的科学发现。美国宇航局称该望远镜是有史以来发射到太空的最大、最强大的望远镜。 该机构于 2021 年底推出了 Webb,并于 2022 年 7 月发布了第一批图像。韦伯的第一张全彩图像由乔·拜登总统展示。 其中一张图像展示了大约 130 亿年前的早期宇宙最清晰的图景。

NASA Administrator Bill Nelson marked the anniversary with a statement. He said, "In just one year, the James Webb Space Telescope has transformed humanity's view of the cosmos, peering into dust clouds and seeing light from faraway corners of the universe for the very first time."Most recently, NASA celebrated the Webb’s one year anniversary by releasing one of its latest images. The image showed a cloud collection of 50 stars in the process of forming. NASA said the image showed an area of space that is full of hydrogen gas and dust. Scientists said the image was a good representation of this brief period in a star’s life. At around the same time, researchers announced they had used data from the Webb to identify the most distant, active supermassive black hole ever observed. Scientists say the black hole sits in a galaxy called CEERS 1019. The galaxy is thought to have existed about 570 million years after the Big Bang – the explosion many scientists believe created the universe.

美国宇航局局长比尔·尼尔森发表声明纪念这一周年纪念日。 他说:“仅仅一年的时间,詹姆斯·韦伯太空望远镜就改变了人类对宇宙的看法,第一次凝视尘埃云,看到来自宇宙遥远角落的光。”最近,美国宇航局发布了一张最新图像来庆祝韦伯太空望远镜一周年纪念日。 该图像显示了正在形成过程中的由 50 颗恒星组成的云团。 美国宇航局表示,该图像显示了一个充满氢气和灰尘的太空区域。 科学家表示,这张照片很好地体现了恒星生命中这段短暂的时期。大约在同一时间,研究人员宣布他们已经利用韦伯望远镜的数据来识别迄今为止观测到的最遥远、活跃的超大质量黑洞。 科学家表示,该黑洞位于一个名为 CEERS 1019 的星系中。人们认为该星系存在于大爆炸之后约 5.7 亿年,许多科学家认为大爆炸创造了宇宙。

The black hole discovery and others that received help from the Webb were in part made possible through the telescope’s infrared instruments. The instruments collect infrared waves passing through gas and dust that can hide objects in space. The infrared system also shows light from more distant parts of the universe.The Webb’s instruments have also confirmed the distances of some of the farthest galaxies ever observed, NASA reported. In addition, the telescope’s data has provided more detailed information than ever before about the makeup of planet atmospheres. And the instruments have also led to discoveries about the chemicals and gases that exist around collections of stars and exoplanets outside of our solar system.
