Here's one example, where they measure the separation of spectral features from the OH molecule in a fairly distant galaxy and use that information to put a limit on how much variation there coul…

Distant objects do tend to look redder because of redshift, but the mottled pattern is a bit too regular to all be distant galaxies. It's more likely to be the noise in the data used for the red …

> If I zoom in, I see a reddish mottled pattern. Is that sensor noise, background radiation, or something else? I assume you mean the pattern that is distributed across the general image? That…

The background image is not data from Webb; it is a near-infrared image from the 2 Micron All-sky Survey (2MASS). See @skybrian's comment: https://news.ycombinator.com/item?id=400…

Growing up, my brothers and I would play "I spy" by identifying a color. E.g., "I spy with my little eye something that is orange".

> I don't think the 39m primary E-ELT is designed to do full sky surveys. AFAIK it is to do targeted observations using multiple instruments. Correct. I wasn't able to quickly find the m…

@randomcarbloke probably means installing/soldering the components onto the board. E.g., https://www.digikey.com/en/maker/blogs/2021/how-to-populate-... …

If they're ~identical construction and being mirrored so that they have the same write/read pattern history, it could trigger the same failure mode simultaneously.
