The image size of this camera is unbelievably huge in its coverage.

Most telescopes take pictures of objects - this one takes pictures of the entire sky. And will do so in a time-lapse fashion for 10 years.

It's simultaneously more in line with a human's experience than an obscure wavelength of tiny object not visible to the naked eye - it takes a high-resolution picture that's similar to what you'd see if you look at the sky. But it's also profoundly grand beyond a human's experience because of just how much stuff is collected.

Just beautiful. Idk why, some part of me feels there's repeating fractals that differ in large chunks of time.

At the same time somehow every chunk is genuinely different. So much space my mind wants there to be a trick of some kind that reduces it

I’m the person in the chain that takes the scientific data and maps it into these color images used in the viewer (among other responsibilities). I spent a long time researching and developing the software that as close as possible maps the data into human perception. It means so much to see people out there appreciating our work, and following what Rubin will achieve. So that you for taking your time to check it out!

Hey! Former astronomer here; I used to work a lot with SDSS data products. Do you happen to have a link to any sort of photometry DB/catalog for Rubin? Basically I’m looking to grab a ton of data but I’ve been out of the field for a while and I’m not sure where they publish their data sets and which ones you’d recommend as being relatively accessible.

You want to check out the early science release info at https://rubinobservatory.org/for-scientists/resources/early-... . This is all early science from preliminary data. It is mostly to help people ramp up developing their software against the type of things they will be seeing in the future. There some known issues and gotchas outlined in the release. Hopefully this will be enough to whet your appetite. The data seen in this sky viewer is part of the Data Preview 2.

I always laugh when I tell people I have a wide angle telescope, but Rubin takes that to an entirely different level.
