Discover the science mission of NASA’s James Webb Space Telescope (JWST), from exoplanet atmospheres to the first light in the universe—and more!

The James Webb Space Telescope (JWST) is a space telescope designed to conduct infrared astronomy. As the largest telescope in space, it is equipped with high-resolution and high-sensitivity instruments, allowing it to view objects too old, …

Feb 13, 2025 · Ancient galaxies are so far that as space expands, their light has stretched into infrared wavelengths — Webb's specialty. Did that large spiral galaxy towards the bottom of the image catch your eye? Named LEDA 2046648, it’s a little over a billion light-years from Earth and located in the constellation Hercules.

詹姆斯·韦伯空间望远镜 （英語： James Webb Space Telescope，简称 JWST，中国大陆官方译名为 詹姆斯·韦布空间望远镜）是已發射的 紅外線 太空望遠鏡，原计划耗费5亿美元并于2007年发射升空 [8]。

6 days ago · The James Webb Space Telescope is a giant leap forward in our quest to understand the Universe and our origins. Webb is examining every phase of cosmic history: from the first luminous glows after the Big Bang to the formation of galaxies, stars, and planets to the evolution of our own solar system.

Feb 13, 2025 · NASA’s James Webb Space Telescope has captured direct images of multiple gas giant planets within an iconic planetary system. HR 8799, a young system 130 light-years away, has long been a key target for planet formation studies.

詹姆斯·韦布空间望远镜（英文：James Webb Space Telescope，缩写：JWST，简称：韦布空间望远镜，），是美国航空航天局、欧洲航天局和加拿大国家航天局联合研发的红外线观测用空间望远镜，为哈勃空间望远镜的继任者。

Aug 22, 2024 · The James Webb Space Telescope (sometimes called JWST or Webb) is an orbiting infrared observatory that will complement and extend the discoveries of the Hubble Space Telescope, with longer wavelength coverage and greatly improved sensitivity.

Mar 17, 2025 · NASA’s James Webb Space Telescope has captured direct images of multiple gas giant planets within an iconic planetary system. HR 8799, a young system 130 light-years away, has long been a key target for planet formation studies. The observations indicate that the well-studied planets of HR 8799 are rich in carbon dioxide gas.
