See Earth's atmosphere glow gold in gorgeous photo taken from the ISS

在这张从国际空间站拍摄的华丽照片中，你可以看到地球的大气层闪耀着金色的光芒

A golden glow illuminates Earth's horizon in a stunning new image from the International Space Station.

一幅震撼的新照片显示，国际空间站上耀眼的金色光芒照亮了地球的地平线。

The atmospheric glow, or airglow, captured in the new photo occurs when sunlight interacts with atoms and molecules within Earth's atmosphere. The new photo, which NASA shared on Jan. 21, shows a bright golden glow arching above Earth, along with an auburn-colored band against the dark contrast of a starry sky backdrop.

这张新照片捕捉到的大气辉光，也称为气辉，是由于阳光与地球大气中的原子和分子相互作用而产生的。美国宇航局在1月21日分享的这张新照片展示了一个明亮的金色光弧环绕在地球上方，以及在星空背景的黑暗对比中显现出的栗色带。

The photo was taken at an altitude of 258 miles (415 kilometers) as the orbiting lab flew over the Pacific Ocean northeast of Papua New Guinea, according to a NASA image description.

根据美国宇航局（NASA)的图像描述，这张照片是在距离地面258英里（415公里）的高度拍摄的，当时轨道实验室飞越了巴布亚新几内亚东北部的太平洋。

Airglow is the result of an interaction in Earth's upper atmosphere, whereby molecules of nitrogen, oxygen, sodium and ozone are excited by ultraviolet radiation from sunlight and, in turn, emit light as they collide with one another. This type of light show is best seen at night. So the recent photo was captured at a high exposure, allowing enough light to enter the camera to see Earth and the star-studded sky.

气辉是地球上层大气中一种交互作用的结果，在这种作用下，氮、氧、钠和臭氧分子受到阳光中的紫外线辐射激发，并在相互碰撞时发出光。这种光影表演在晚上最为明显。因此，这张照片是在高曝光条件下拍摄的，使得足够的光线进入相机，从而能够看到地球和繁星点点的夜空。

Traveling at a speed of 5 miles (8 kilometers) per second, the International Space Station (ISS) orbits Earth about every 90 minutes, traveling through 16 sunrises and sunsets in a 24-hour period. The space station experiences about 45 minutes of daylight and 45 minutes of darkness in each revolution.

国际空间站 (ISS) 以每秒 5 英里（8 公里）的速度绕地球飞行，每 90 分钟完成一圈，在 24 小时内经历 16 次日出和日落。空间站在每次轨道运行中大约经历 45 分钟的白天和 45 分钟的黑夜。

In addition to the colorful golden auburn glow, the photo captures white wispy cloud tops above the dark blue of the Pacific Ocean. Parts of the space station itself also snuck into view, including the Prichal docking module and the Nauka multipurpose laboratory module, both of which belong to Russia's space agency Roscosmos.

除了五彩斑斓的金棕色光辉，这张照片还捕捉到了太平洋深蓝色上方的洁白云朵。照片中还隐约可见空间站的一部分，包括普里查尔对接模块和纳乌卡多功能实验室模块，这两个模块都属于俄罗斯的航天局俄罗斯航天集团。

Captured on the left side of the image, Prichal is attached to Nauka, providing five available docking ports to accommodate multiple Russian spacecraft, along with fuel transfer capabilities. The Nauka module — used to conduct experiments as the primary laboratory of the ISS' Russian segment — arrived at the space station in July 2021, followed closely by Prichal in November 2021.

图像左侧捕捉到的Prichal与Nauka相连，提供五个可用的对接港口，以容纳多艘俄罗斯宇宙飞船，并具备燃料转移能力。Nauka模块作为国际空间站俄罗斯段的主要实验室，用于开展实验，于2021年7月抵达空间站，紧接着在2021年11月到达的Prichal。
