Where NASA Posts Its Best Space Photos, and How to Find Them

NASA 在哪里发布其最棒的太空照片，以及如何找到它们

The recent mission to the moon by Artemis II astronauts was memorable, inspiring, and scientifically important for so many reasons. It also brought us a treasure trove of new images and videos ready to be added to NASA’s vast library of content. “阿尔忒弥斯 2 号”（Artemis II）宇航员最近的登月任务因诸多原因而令人难忘、备受鼓舞且具有重要的科学意义。它还为我们带来了一批新的图像和视频宝库，随时准备被添加到 NASA 庞大的内容库中。

Consider this photo of Earth from more than 250,000 miles away, for example, taken from the other side of the moon. Or these widely shared pictures of our home planet from inside the Orion capsule, which were taken using iPhone 17 Pro Max phones. Truly out of this world snaps, but taken using a device many of us have in our pockets. 以这张从 25 万英里外、月球背面拍摄的地球照片为例。或者这些在社交媒体上被广泛分享的、从“猎户座”（Orion）飞船内部拍摄的地球照片，它们是用 iPhone 17 Pro Max 拍摄的。这些照片确实超凡脱俗，但却是用我们许多人兜里都有的设备拍摄的。

These images have popped up all across social media, but what you might not know is that NASA makes its huge library of images and videos available for anyone to dig through, marvel at, and reshare. Because NASA is funded by the US government, most of its published media is released into the public domain. 这些图像在社交媒体上随处可见，但你可能不知道的是，NASA 将其庞大的图像和视频库向所有人开放，供大家挖掘、欣赏和转发。由于 NASA 由美国政府资助，其发布的大部分媒体内容都属于公共领域。

That’s the good news. The bad news is that it’s not immediately obvious where this library is and how you can access it. 这是好消息。坏消息是，这个库在哪里以及如何访问它，并不是显而易见的。

If you’re ready to browse through decades’ worth of incredible photos and videoclips from NASA—from giant star constellations to spacesuit designs—here’s how to get started. A word of warning though: It’s easy to get lost for hours inside these collections. 如果你准备好浏览 NASA 数十年来令人难以置信的照片和视频片段——从巨大的星群到宇航服设计——以下是入门方法。不过要提醒你：很容易在这些收藏中迷失数小时。

The NASA Image and Video Library

NASA 图像和视频库

Let’s start with the biggest resource: The NASA Image and Video Library. This is where you’ll find just about every image, video, and audioclip that NASA wants to share, from astronaut photos and space conferences to planet shots and satellite imagery. By default, you get to see the newest uploads first, but you can also click Trending & Popular to see frequently viewed content from across the years. 让我们从最大的资源开始：NASA 图像和视频库。在这里，你可以找到 NASA 想要分享的几乎所有图像、视频和音频片段，从宇航员照片和太空会议到行星照片和卫星图像。默认情况下，你会先看到最新的上传内容，但你也可以点击“趋势与热门”（Trending & Popular）来查看多年来浏览量最高的内容。

Click on an image or video here to get a wealth of information about it, including what it shows and when it was captured. Some of the captions here are mini-essays, and a lot of the content on this portal comes with EXIF data included, which will be of interest to photographers (or anyone who wants to know which pictures were snapped with an iPhone 17 Pro Max). 点击此处的图像或视频，即可获取有关它的丰富信息，包括它展示的内容和拍摄时间。这里的一些说明文字就像小短文，而且该门户网站上的许多内容都包含 EXIF 数据，这对摄影师（或任何想知道哪些照片是用 iPhone 17 Pro Max 拍摄的人）来说会很有趣。

As wonderful as this resource is, it’s also difficult to sift through, unless you specifically know what you’re looking for. You’re basically relying on the search box at the top, and common keywords can return dozens and dozens of pages of results. Try being as specific as you can with search terms. Also, use the keywords on each photo and video listing to find related content. 尽管这个资源非常棒，但除非你明确知道自己在找什么，否则很难进行筛选。你基本上只能依赖顶部的搜索框，而常用的关键词可能会返回几十页的结果。尝试让搜索词尽可能具体。此外，利用每个照片和视频列表上的关键词来查找相关内容。

NASA Images

NASA 图像门户

In addition to the NASA Image and Video Library page, there’s also NASA Images—which includes a link to the Image and Video Library. (Those of you at the back, try to keep up). NASA Images isn’t as comprehensive as the Image and Video Library, but it is better organized, and it’s easier to find recent content here. 除了 NASA 图像和视频库页面外，还有一个“NASA 图像”（NASA Images）门户——其中包含指向图像和视频库的链接。（坐在后面的同学，跟上节奏）。“NASA 图像”虽然不如图像和视频库全面，但它组织得更好，在这里更容易找到最近的内容。

At the very top of the portal is the NASA Image of the Day, which is a great way to see the best that the NASA photo and video database has to offer. There’s also an Image of the Day archive you can use to browse back through time and discover even more stunning shots. Sadly, you can’t browse the archive by date. 门户网站的最上方是“NASA 今日图片”，这是查看 NASA 照片和视频数据库中最棒内容的好方法。还有一个“今日图片”存档，你可以用它回顾过去，发现更多令人惊叹的照片。遗憾的是，你无法按日期浏览存档。

Downloading content from NASA Images is straightforward, though you don’t get as much information on each picture as you do in the main library. It’s also easier here to find images grouped by collections, whether that’s photos taken by a specific telescope or organized by a particular mission. 从“NASA 图像”下载内容非常简单，尽管你无法像在主库中那样获得每张照片的详细信息。在这里，按集合对图像进行分组也更容易，无论是特定望远镜拍摄的照片，还是按特定任务组织的图像。

NASA Johnson Flickr

NASA 约翰逊航天中心 Flickr

Another way into the NASA content archive is through the NASA Johnson Flickr page. If you’ve never heard of Flickr before, it used to be the best place for storing and sharing images and videos in high resolution, before Apple and Google got around to properly developing their own apps for the job. Flickr still has plenty of fans, and the NASA account for the Johnson Space Center shows off the strengths of the portal. 进入 NASA 内容存档的另一种方式是通过 NASA 约翰逊航天中心（NASA Johnson）的 Flickr 页面。如果你以前没听说过 Flickr，它曾经是存储和分享高分辨率图像和视频的最佳场所，后来苹果和谷歌才开始开发自己的相关应用。Flickr 仍然拥有大量粉丝，而 NASA 约翰逊航天中心的账号展示了这个平台的优势。

There are more than 63,500 photos available through this Flickr account at the time of writing, and unlike the main NASA Image and Video Library, they’re all neatly organized into albums. It’s not difficult to find shots of a particular astronaut or from a particular mission, for example. Each image comes with plenty of information about the subject, as well as download links. 在撰写本文时，通过此 Flickr 账号可以获取超过 63,500 张照片，与主要的 NASA 图像和视频库不同，它们都被整齐地整理成相册。例如，找到特定宇航员或特定任务的照片并不难。每张图片都附有关于主题的大量信息以及下载链接。

A search function helps you dig deeper into the NASA Johnson account. Even better, if you’ve got your own Flickr account, you can follow NASA and have new uploads to the account brought to your attention. It can take a little longer for photos to show up here, and the feed only has pictures from the Johnson Space Center, but it’s perhaps the best option for ease of navigation. 搜索功能可以帮助你深入挖掘 NASA 约翰逊航天中心的账号。更好的是，如果你有自己的 Flickr 账号，你可以关注 NASA，并及时收到该账号的新上传内容。照片在这里出现的时间可能会稍晚一些，而且信息流中只有来自约翰逊航天中心的图片，但对于导航的便捷性来说，这可能是最好的选择。

NASA 社交媒体

Finally, there’s NASA’s various social media accounts. If you’re already spending a lot of time on social media and want to see new content from NASA occasionally pop into your feeds, check out the agency on X, Instagram, and Facebook for starters. 最后是 NASA 的各种社交媒体账号。如果你已经花了很多时间在社交媒体上，并且希望偶尔在信息流中看到 NASA 的新内容，那么可以先关注该机构在 X、Instagram 和 Facebook 上的账号。

A lot of this content is very well organized into collections and albums, and it’s tagged with the relevant information. However, getting downloads (especially at the best resolution) can be tricky, depending on the platform. Social media is really most suitable for the occasional dip into the images and videos that NASA has to offer. 其中许多内容被很好地组织成集合和相册，并贴有相关信息标签。然而，根据平台的不同，获取下载（尤其是最高分辨率的下载）可能会比较棘手。社交媒体确实最适合偶尔浏览一下 NASA 提供的图像和视频。

One of the frustrations with trying to collect images and video this way is that there are so many different accounts to keep track of. On the X platform alone, you’ll find accounts specific to the Artemis missions, the International Space Station, everything connected to Mars, and the Webb telescope. It’s a lot to keep track of. 试图通过这种方式收集图像和视频的一个令人沮丧之处在于，有太多的不同账号需要关注。仅在 X 平台上，你就会发现专门针对“阿尔忒弥斯”任务、国际空间站、与火星相关的一切以及韦伯望远镜的账号。要跟踪的内容实在太多了。
