That is awesome. I'm looking forward to seeing the results of unscrambling the ring to see what the galaxy behind looks like. Hopefully someday we will be able to use a solar gravitation lens to look at neighboring exoplanets: https://www.youtube.com/watch?v=NQFqDKRAROI https://arxiv.org/abs/1802.08421

And hopefully some day we'll build a solar-gravitation lens to look at the surface of one of these exoplanets: https://arxiv.org/abs/1802.08421 ...with a very interesting video that someone made on that paper: Someone also made an interesting Youtube video of the concept: https://www.youtube.com/watch?v=NQFqDKRAROI

>Needs new propulsion like nuclear thermal or something to get to target distance in our lifetimes. Here's a cool video describing solar sails that are supposed to be able to accelerate up to a final velocity of 22 AU/year, which get things to 550AU in 25 years. https://www.youtube.com/watch?v=NQFqDKRAROI&t=883s This video was based on the paper: https://arxiv.org/abs/1802.08421

Here's a fun video on the concept of using gravitational lensing from the sun: https://www.youtube.com/watch?v=NQFqDKRAROI ...along with a different paper, where they are going for 1km resolution: https://arxiv.org/abs/1802.08421
