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 hope the data releases are a bit better than what I've seen from recent telescopes.

The common pattern seems to be that the majority of data is locked away behind multi-year embargo periods, or never released to the public at all with no explanation why, with only the smallest little crumbs of raw data actually released to the public, and usually years out of date. Also you have to go through some kafkaesque chain of technologies/servers/bureaucracy to get access to that little bit of data.

It's a little depressing to me when the public funds these telescopes and then get snubbed when it comes to getting access to the data they produce.
