NASA的詹姆斯·韦伯太空望远镜和哈勃太空望远镜联合起来研究一个被称为MACS0416的膨胀星系团。由此产生的全色图像结合了可见光和红外光，组合成有史以来最全面的宇宙视图之一。MACS0416距离地球约43亿光年，是一对相互碰撞的星系团，它们最终将合并成一个更大的星系团。

2023年11月9日 M1: The Crab Nebula Image Credit: NASA, ESA, CSA, STScI; Tea Temim (Princeton University) Explanation: The Crab Nebula is cataloged as M1, the first object on Charles Messier’s famous 18th century list of things which are not comets. In fact, the Crab is now known to be a supernova remnant, debris from the death explosion of a massive star witnessed by astronomers in the year 1054. This sharp image from the James Webb Space Telescope’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument) explores the eerie glow and fragmented strands of the still expanding cloud of interstellar debris in infrared light. One of the most exotic objects known to modern astronomers, the Crab Pulsar, a neutron star spinning 30 times a second, is visible as…

使用NASA詹姆斯·韦伯太空望远镜的科学家刚刚在揭示行星是如何形成方面取得了突破性的发现。通过观察原行星盘上的水蒸气，韦伯证实了一个物理过程，即被冰覆盖的固体从原行星盘的外部区域漂流到岩石行星区。

2023年10月10日 Hidden Orion from Webb Image Credit & License: NASA, ESA, CSA, JWST; Processing: M. McCaughrean & S. Pearson Explanation: The Great Nebula in Orion has hidden stars. To the unaided eye in visible light, it appears as a small fuzzy patch in the constellation of Orion. But this image was taken by the Webb Space Telescope in a representative-color composite of red and very near infrared light. It confirms with impressive detail that the Orion Nebula is a busy neighborhood of young stars, hot gas, and dark dust. The rollover image shows the same image in representative colors further into the near infrared. The power behind much of the Orion Nebula (M42) is the Trapezium – a cluster of bright stars near the nebula’s…
