好吧,但是为什么你不能把韦伯和哈勃的图像结合起来呢?你可以,今天的特色图片展示了一个令人印象深刻的结果。虽然最近发射的詹姆斯·韦伯太空望远镜(韦伯)的镜面比哈勃望远镜大,但它专门研究红外光,不能看到蓝色,只能看到橙色左右。相反,哈勃太空望远镜(哈勃)的镜面比韦伯小,不能像韦伯那样看到远的红外线,但不仅可以成像蓝光,甚至可以成像紫外线。因此,韦伯和哈勃的数据可以结合在一起,创造出更多种颜色的图像。斯蒂芬五重奏中的四个星系的特色图像显示韦伯图像为红色,还包括日本在夏威夷的地面斯巴鲁望远镜拍摄的图像。由于韦伯、哈勃和斯巴鲁的图像数据是免费提供的,世界上任何人都可以自己处理这些数据,甚至可以创建有趣的、科学上有用的多天文台蒙太奇。史蒂芬五重奏来自韦伯,哈勃

OK, but why can't you combine images from Webb and Hubble? You can, and today's featured image shows one impressive result. Although the recently launched James Webb Space Telescope (Webb) has a larger mirror than Hubble, it specializes in infrared light and can't see blue -- only up to about orange. Conversely, the Hubble Space Telescope (Hubble) has a smaller mirror than Webb and can't see as far into the infrared as Webb, but can image not only blue light but even ultraviolet. Therefore, Webb and Hubble data can be combined to create images across a wider variety of colors. The featured image of four galaxies from Stephan's Quintet shows Webb images as red and also includes images taken by Japan's ground-based Subaru telescope in Hawaii. Because image data for Webb, Hubble, and Subaru are made freely available, anyone around the world can process it themselves, and even create intriguing and scientifically useful multi-observatory montages.
