    basic astronomical observations

    No, this is not basic. I should really not engage with a troll, but for anyone else curious about why this is cool:

    Current estimates on the size of the sun are on the order of ±1000km. “Wright said different papers using a variety of methods have produced results that differ by as much as 930 miles (1,500 km)”

    This request for cell phone observations is trying to do some wild math way out of my comprehension, based on the flashes of light shining between mountains and valleys on the moon, to calculate the size of the sun down to single-digit kilometer accuracy. That’s three orders of magnitude more accurate than our current measurements. And this type of measurement can only happen during an eclipse.

    To me that is absolutely wild, good job NASA 🚀
