Most of the artifacts you see are actually asteroids. We don't take all the colors at once when making an image. The ccds just count photons that fall on them, so we have giant gla…

If you click on the search icon, there are some quick links to fields across the sky so you don't need to scroll as much. There are some interface tweaks and ui stuff that will be …

I have a publication that will be done soon™. I have been preparing it for a while, but I keep finding edge cases to fix, and ways to make things even better that I keep changing t…

We are getting pretty far outside my area of expertise / knowledge on this topic here, but I know I and others agree with you here. There is a Rubin Observatory data access policy …

They are both fairly rare, and or like you said wrong scale (for this data release at least). There is actually one in this field, but it is below the noise floor of this image, it…

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 mos…

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 an…

You are not wholly wrong! There is both a supporting structure for the mirror, AND a glass lens in front of the sensor to further flatten the incoming light. The interesting thing …

The filters used for this range from near infrared to near uv. We used 4 different filters in all (for this image, the telescope has more). In general yes to fully appreciate all t…

Image creator here. We do dark field subtraction, as well as many other instrumental calibrations. What you are seeing is the fundamental photon noise. Because it is statistical in…

Image creator here. Now imagine, when the survey is done, we will be able to see even fainter objects and image an area of the sky 1000x times this size.

Image creator here. This is such a massive dataset, most of the image processing needed to be custom written software pipelines. It not really practical for every pixel to be hand …

I agree their results are also great! We do go a bit deeper, but he big difference it the speed we are able to build these images. We are able to image a larger area of the sky in …

I'm the Rubin team member responsible for mapping the data into RGB images. I have been a long time reader of hacker news, but finally made an account to comment on this. I wanted …
