Glad you expressed uncertainity. Indeed We can see some exoplanets directly. I also only learned this very recently.

- andrewflnr 2y agoIt only happened recently, relative to SETI efforts overall.
- bluGill 2y agoThanks for the correction. Note that all those planets are very large (none of significantly smaller than Jupiter, and most are much larger). Also all are very close to earth, and the "smaller" it is the closer it is". Physics provides limits to what we will ever be able to directly observe from earth (though I'm not an astrophysicist, find one if you want to know more details, I'm confident in that statement anyway but do understand my expertise isn't here)
