Southern Ring Nebula from the James Webb Telescope

从詹姆斯·韦伯望远镜拍摄的南环星云

This planetary nebula, known as the Southern Ring Nebula, is an image of a dying star. It is expelling gas and dust as it dims, and the Webb image provided much new information about the ionized gas contained. This image is taken with mid-infrared light and reveals that it is actually a binary star at the center. The system is 2000 light years from Earth. The dimmer star at the center of this scene has been sending out rings of gas and dust for thousands of years in all directions, and NASA's James Webb Space Telescope has revealed for the first time that this star is cloaked in dust.

这个被称为南方环状星云的天体,是一颗垂死恒星的图像。它正在释放气体和尘埃,随着亮度下降, Webb 提供了关于其中离子化气体的新信息。这张图像使用中红外光拍摄,揭示它实际上是一个双星系统。该系统距离地球2000光年。这张图像中中心较暗的恒星已经向各个方向持续释放出数千年来的气体和尘埃环,而NASA的詹姆斯·韦伯太空望远镜首次揭示了这颗恒星被尘埃所遮蔽的事实。

This image is taken with near-infrared light and shows more detail of the features of the expelled gas and dust.

这张图像使用近红外光拍摄,显示了喷出气体和尘埃的更多细节。
