Theres no binary planets because they demoted Pluto and Charon. 🤷♂️ that would be my quick answer.
For Dark Site Finder, you gave New York City as an example of extreme light pollution (sounds right), but it turns out if you use the right filter the Milky Way is visible. https://science.nasa.gov/image-article/apod-2026-october-15-the-milky-way-over-manhattan/ In this case the right filter being only capture near infrared. I'm actually surprised how bright the city is in near infrared, I had assumed remote controls used near infrared because there wasn't much going on there, maybe inside a house is different?
https://youtu.be/YFtm6lRRaec I just watched this video by Elon Musk. At minute 10 he talks about Super computing and next year being orders of magnitude greater than today. And most of it for Vera Rubin Compute. That shows what the amount of data coming down and what will be required to analyze it.
