A much better idea is the terrascope, using Earth's upper atmosphere as a refracting lens. This wouldn't require a multi-decade mission, nor a huge sunshield.

- someguydave 4y agothe sunshield would not be huge at 900 AU
- TomGullen 4y agoAn excellent video on this: https://www.youtube.com/watch?v=jgOTZe07eHA https://www.youtube.com/watch?v=jgOTZe07eHA Earths atmosphere and weather affects this sort of telescope IIRC and will filter out some lightwaves but seems like a much easier win
- e12e 4y agoInteresting. I wonder if there are planets with atmosphere in our solar system that would allow testing this from earth orbit (eg: iss/satellite looking at objects lensed by Jupiter etc, because the refraction and distances work out).
