    The paper has more details. What's interesting to me is that the key innovation isn't the deformable mirror but rather the design of a wavefront sensor that focuses on coronal features (instead of the "grain" on the solar surface prior systems used).

      Utterly alien.

      For reference, the field of view here is about 2.5x the diameter of the Earth. Astronomical scales remain mind bending to me.

        It's not even comprehendable for our brains. The scale, temperature, and velocities of these fluffy pixels is just enormous. It's high energy physics, CFD, all in real life and real time.

        What fascinates me is the stable structure in the first video. Everything is so ephemeral yet that structure remains largely in place and in the same shape yet it's internals are seething.

          What a time to be alive. I can look at my magic enchanted light-box and observe "rain" on the surface of the sun.

          It's almost nice that mysteries remain - apparently, the physical mechanism behind solar spicules [1] remains "hotly" (!!) debated.

            With NSO (not NSO.edu but the cyberweapons/malware company) there is a hidden tenuous pun.

            Adaptive optics started in a secret space weaponry research funded by SDI.

            When a few profs independently proposed the idea in their NSF research grant proposal they were told - we already know this stuff.

                • GolfPopper a day ago

                  I think that's why H.P. Lovecraft's work still resonates - he first captured that cosmic sense of horror that came with humanity starting to understand our place in the universe, and how tiny and insignificant it really is.

                  I caught some of that sense not too long ago, looking at the Moon with a new-to-me (amateur) telescope and wide-field eyepiece. Some combination of the seeing conditions and optics let my mind really connect with what I was seeing, in a way it never had before in decades of amateur astronomy. I understood that what I was looking at - grokked it, if you will allow - across an abyss that was incomprehensibly vast to me, but still only the tiniest of distances of the scale of the solar system, let alone the universe, was a whole other world, a vast globe of rock and dust, moving through the void, its mountains and valleys utterly empty of the air, water life that has always surrounded me.

                  My description doesn't really do it justice. It was the first time I'd ever really gotten a sense for the scales involved in my hobby, where what I was looking at felt real and not just an image through an eyepice and it made me catch my breath. Amazing, disturbing, and a little frightening all at once.

                  • jvanderbot 18 hours ago

                    Once, I had the opportunity to view Saturn through a university telescope. You know the kind with a motorized dome and car sized actuators and such.

                    It was so, so visible and yet so, so far. Somehow using all that power to see it in real time and still have it be small but look so insanely huge somehow.

                    I had this vertigo and the scale of the solar system kind of rushed at me. Just like you say.

                  • itishappy 2 days ago

                    I feel like the moment you learn the relative scales, it's over, there's no going back.

                    There's a billion WWII ending atom bombs going off every day up there. How are we still ok?

                      My preferred design for fusion reactors uses gravitational confinement and are placed 150 million miles away.

                          With enough distance, even largest hypernovae are just tiny sparkles on the background of the sky.

                              Hey, at least we can’t hear the screaming (/s).

                              Distance/dilution really is the solution eh? Besides, without all those fusion bombs going off our air would be liquid/solid, which is extremely inconvenient.

                              There was this sci-fi story set on the sun. Humans interact with sentient plasma, some as old as the universe. Forgetting the name.

                                  They talk about creating an artificial star by stimulating light at 90km in the atmosphere, would it be useful to have a satellite that you can reposition that would shine a calibrated light source back at earth? I imagine you could also do some tricks with the light source to maybe get more accurate data about the atmospheric distortions.

                                    The satellite beam wouldn’t go through the parts of the atmosphere the telescope is pointing. You need to calibrate exactly for the spot the telescope is observing.

                                      This is so exciting! My colleagues are doing research in astronomical imaging except on the more theoretical side of things - it's really neat to come across cool downstream applications like that!

                                        “Clearest images to date” - wouldn’t images taken from space, much closer to the sun, be clearer?
