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 glass filters that allow specific wavelengths through. We

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 coming down stream that will help with some of this as

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 things fast enough that I need to re-work the paper. The code

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 out there. Don't quote me on the exact specifics b

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 is very small and very faint. There will be others in the f

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 develo

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

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 about the spikes in our images is that they stay fixed in im

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 the color information as a human we need to generate differen

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 nature, you can never completely eliminate it. We could hav

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 inspected. A few defects (and bright asteroids) imprinted th

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 each exposure, and are able to collect more light. This will

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 to thank everyone here for their interest and taking th
