That circular image can be corrected with computer software to a normal image. It will create images of those exoplanets with great detail.
Not planets, galaxies. The nearest one is 3.8 billion light years away, while the primary one of interest is a quasar clear across the universe.
Yes, it’s going to be absolutely fascinating to see how much detail they’ll be able to see in something that’s that far away! I’m a believer, but man, the quasar is soooo far away (one source said 17 billion light years), it’s kind of hard to believe they’ll be able to see much more than a bright spot. I’ll be happy just to see the galaxy the quasar is part of.
