You can see SDSS kick in around Y2K.

你可以看到SDSS在2000年左右启动。

What's new in SDSS-V is that we're making the focal plane entirely robotic.

SDSS-V 的创新之处在于将焦平面完全变成了机器人。

But in SDSS we use new instruments on these old telescopes to make them interesting.

但在SDSS，在这些旧望远镜上连接了新仪器，使它变得更有趣。

In SDSS-V, we're mapping six million stars where we think we can measure their age.

在SDSS-V，正在测绘600万颗恒星的图像，认为可以测算它的年龄。

And this brings me to the most important point about SDSS.

这就引出了关于SDSS最重要的一点。

And in SDSS, we're looking at over half a million supermassive black holes, to try to understand how they formed.

在SDSS，观察了超过50万个超大质量黑洞，试图了解它是如何形成的。

In SDSS, we divide the sky into three mappers: one for the stars, one for the black holes and one for the galaxies.

在SDSS，将天空分割成三个探索区域：一个探索恒星，一个探索黑洞，一个探索星系。

So in SDSS-V, we're going back to each part of the sky multiple times in order to see how these objects change over time.

所以在SDSS-V，要多次回到天空的每个部分，为了看看这些观测对象是如何随着时间变化的。

You can see SDSS kick in around Y2K. If we stay on this line, we will map every large galaxy in the observable universe by 2060.

您可以看到 SDSS 在 Y2K 前后开始发挥作用。 如果坚持这条线，到 2060 年将绘制出可观测宇宙的每个大星系。

And this brings me to the most important point about SDSS. Because, yeah, the stars, the galaxies, the black holes, the robots -- that's all super cool.

这让想到了关于 SDSS 的最重要的一点。因为，是的，星星、星系、黑洞、机器人——这一切都非常酷。

She was able to do this because SDSS, since its beginning and by mandate from the Sloan Foundation, has made its data both publicly available and usable to a broad range of audiences.

她之所以能做到这一点，是因为SDSS自成立以来，根据斯隆基金会的授权，已将其数据向大众公开，广大群众都可以使用。

Think about it: we've gone from arranging clamshells to general relativity to SDSS in a few thousand years—and if we hang on 40 more, we can map all the galaxies.

在几千年的时间里，已经完成了从整理蛤壳到广义相对论，再到整理SDSS的跨越——如果再坚持40年，将可以绘制出所有星系的样貌。

Hanny van Arkel was a Dutch schoolteacher who was analyzing the public versions of the SDSS data, when she found this incredibly rare type of object, which is now a subject of major study.

哈尼·冯·阿科尔曾经是一名荷兰教师，她在分析SDSS数据的公共版本时，发现了这种极其罕见的星体形态，现在成为了的主要研究对象。

And at SDSS, we're going to the bellies of the beast and zooming way in, to look at these processes where they are occurring in order to understand how Sid Vicious grows up into Ward Cleaver.

而在SDSS，要深入这些星系怪物的内部，一路上将观察到的景象放大，看看这些过程在哪里发生，以便了解恒星变成黑洞的过程。
