Vera Rubin Just Turned the Night Sky Into a Live Data Stream

Added: 2026-05-05

[00:00:00]The first big data dump from the Vera C.

[00:00:01]Rubin Observatory had 800,000 alert >> Yeah. On its very first night.

[00:00:07]>> The Vera C. Rubin Observatory is unlike any other observatory out there because it's this giant thing where astronomers cannot get time on it. Usually when there's an observatory and you you're like, "Hey, I want to look at this candidate dark galaxy in the Perseus cluster. I need four nights." And that application is going to go to whoever's in charge of that telescope time. And they're going to decide from all the applications who is going to get time to look at what. The Vera C. Rubin Observatory is an observatory that is just taking a photo of the entire night sky every three nights. That is its job, like clockwork, fully automated, and that's all it's doing. What that means is it's going to find a lot of data, and what it can do is historically look at what did that position in the night sky look like a month ago, a year ago, 10 years ago because all of the archival astronomical data of maybe the Hubble pointed at it at some point, or maybe the James Webb pointed at it six months ago. It can compare images, and if there's anything different, send out an email alert.

[00:01:09]>> Mhm. And so on its first night >> Jesus.

[00:01:11]>> that this real-time discovery machine was operating, it sent out 800,000 alerts. It found 800,000 candidates for new stuff that scientists could look at.

[00:01:25]The This is So, this is incre- The technology behind it is unreal.

[00:01:30]>> The main thing is it's going from photographs to movies, right?

[00:01:34]>> seeing, for example, asteroids. Mhm. Cuz the asteroids will move, and so that's going to be a motion transient that the Vera Rubin can catch. We're seeing supernovae, which are going to be, "Oh, there was no light bulb there, and then now there's a tiny faint light bulb on that galaxy. That means a star exploded, and we've got about, you know, two or three weeks to catch that star exploding." It's called the Legacy Survey of Space and Time.

[00:01:58]>> Time. The LSST, that's the program. It's for 10 years it's going to go along.

[00:02:03]These alerts are going to be insane.

[00:02:06]Um It's expected to generate up to 7 million alerts per night. Yeah. And we're already on track because with the first night it was already 800,000.

[00:02:15]>> I mean, this is incredible because there's not that many astronomers out there. Right.

[00:02:19]>> Okay? In the world. And those astronomers don't have a lot of time.

[00:02:23]Right.

[00:02:23]>> So, this is really the advent, I think, of decentralized astrophysics research.

[00:02:28]Like now we can have citizen scientists, for example. If you're like in a high school, this is an incredible resource now to do small little projects if you I don't know, you want to get ahead Right.

[00:02:37]in your college application. [laughter] This is something you could do. You could go on the Vera Rubin website and find data and be like, "Hey, which alert do I want to like dig a little bit deeper into?"
