韦伯第一张照片拍摄两年后：与企鹅星系和蛋星系一起庆祝
The distorted spiral galaxy at center, the Penguin, and the compact elliptical at left, the Egg, are locked in an active embrace. This near- and mid-infrared image combines data from NASA’s James Webb Space Telescope’s NIRCam (Near-Infrared Camera) and MIRI (Mid-Infrared Instrument), and marks the telescope’s second year of science. Webb’s view shows that their interaction is marked by a glow of scattered stars represented in blue. Known jointly as Arp 142, the galaxies made their first pass by one another between 25 and 75 million years ago, causing “fireworks,” or new star formation, in the Penguin. The galaxies are approximately the same mass, which is why one hasn’t consumed the other.

To celebrate the second science anniversary of NASA’s James Webb Space Telescope, the team has released a near- and mid-infrared image on July 12, 2024, of two interacting galaxies: The Penguin and the Egg.
Webb specializes in capturing infrared light – which is beyond what our own eyes can see – allowing us to view and study these two galaxies, collectively known as Arp 142. Their ongoing interaction was set in motion between 25 and 75 million years ago, when the Penguin (individually cataloged as NGC 2936) and the Egg (NGC 2937) completed their first pass. They will go on to shimmy and sway, completing several additional loops before merging into a single galaxy hundreds of millions of years from now.

位于中心的扭曲螺旋星系企鹅星系和左侧的紧凑椭圆星系蛋星系被紧紧地拥抱在一起。这幅近红外和中红外图像结合了NASA詹姆斯·韦伯太空望远镜的近红外相机（NIRCam）和中红外仪器（MIRI）的数据，标志着该望远镜进行科学研究的第二年。韦伯的观测显示，它们之间的相互作用以蓝色表示的散射恒星的辉光为标志。这两个星系被称为Arp 142，它们在2500万到7500万年前第一次彼此擦肩而过，在企鹅星系中引发了“烟花”，即新恒星的形成。两个星系的质量大致相同，这就是为什么一个星系没有吞噬另一个星系的原因。

为了庆祝NASA詹姆斯·韦伯太空望远镜进行科学研究两周年，该团队于2024年7月12日发布了一张近红外和中红外图像，展示了两个相互作用的星系：企鹅星系和蛋星系。
韦伯专注于捕捉我们肉眼无法看到的红外光，使我们能够观察和研究这两个被统称为Arp 142的星系。它们的持续相互作用始于2500万到7500万年前，当时企鹅星系（单独编号为NGC 2936）和蛋星系（NGC 2937）完成了首次穿越。它们将继续摇摆，完成若干次额外的绕行，最终在数亿年后合并成一个单一的星系。
