2023年4月7日 · A new mid-infrared image from NASA’s James Webb Space Telescope shows the supernova remnant Cassiopeia A (Cas A), created by a stellar explosion seen from Earth 340 years ago. Cas A is the youngest known remnant from an exploding, massive star in our galaxy.

2023年12月10日 · NASA’s James Webb Space Telescope’s new view of Cassiopeia A (Cas A) in near-infrared light is giving astronomers hints at the dynamical processes occurring within the supernova remnant. Tiny clumps represented in bright pink and orange make up the supernova’s inner shell, and are comprised of sulfur, oxygen, argon, and neon from the star ...

2023年4月7日 · Cassiopeia A (Cas A) is a supernova remnant located about 11,000 light-years from Earth in the constellation Cassiopeia. It spans approximately 10 light-years. This new image uses data from Webb’s Mid-Infrared Instrument (MIRI) to reveal Cas A in a new light.

2024年6月13日 · For the first time astronomers have combined data from NASA’s Chandra X-ray Observatory and James Webb Space Telescope to study the well-known supernova remnant Cassiopeia A (Cas A). This work has helped explain an unusual structure in the debris from the destroyed star called the “Green Monster”, first discovered in Webb data in April 2023.

2023年4月7日 · Divine vision is what the James Webb Space Telescope has granted earthbound scientists in a new near-infrared, detailed image of Cassiopeia A (Cas A), a stellar remnant – the clouds of gas, dust and other material left behind when a star dies.

2023年4月7日 · A new mid-infrared image from NASA/ESA/CSA James Webb Space Telescope provides one stunning example. It shows the supernova remnant Cassiopeia A (Cas A), created by a stellar explosion 340 years ago. The image displays vivid colours and intricate structures begging to be examined more closely.

2023年4月8日 · Cassiopeia A (Cas A) is a supernova remnant located about 11,000 light-years from Earth in the constellation Cassiopeia. It spans approximately 10 light-years. This new image uses data from the...

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]。 但由于各种原因，导致项目严重超支，发射時間数次推迟，最新预估总耗费高达100亿美元，发射时间为美国东部时间2021年12月25日7时20分 [9]。 2019年8月28日NASA表示该望远镜首次组装完毕 [10]。 它是 欧洲空间局， 加拿大太空局 和 美国国家航空航天局 的共用计划。 …

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

2023年12月13日 · The James Webb Space Telescope has turned its golden gaze to Cassiopeia A, a spectacular, complex, expanding cloud of hot gas billowing out from a star humanity saw go supernova back in the 1670s. Scanning the wisps and filaments of gas heated by the outward shocks in infrared reveals incredible level of new detail.
