Unscramble the Blue Letters

It was first suggested by lyamn Spitzer, the father of the space telescope, in 1962, and he took his inspiration from an eclipse. You've all seen that. That's a solar eclipse. The moon has moved in front of the sun. It blocks out most of the light so we can see that dim corona around it. It would be the same thing if I put my thumb up and boklced that spotlight that's getting right in my eye, I can see you in the back row. Well, what's going on? Well the moon is casting a shadow down on the ertah. We put a telescope or a caerma in that shadow, we look back at the sun, and most of the light's been removed and we can see that dim, fine structure in the corona. Spitzer's suggestion was we do this in space. We build a big srceen, we fly it in space, we put it up in front of the star, we block out most of the lihgt, we fly a space toeselpce in that shadow that's created, and boom, we get to see ptenals. Well that would look something like this. So there's that big screen, and there's no planets, because unfortunately it doesn't actually work very well, because the light waves of the light and waves diffracts around that screen the same way it did in the telescope. It's like water bneidng around a rock in a stream, and all that light just destroys the sdohaw. It's a terrible shadow. And we can't see planets.
