it was inspiration followed by a lot of mental sweat. >> and it took me two years to figure it out. >> reporter: parker had seen the same clues everyone else saw. earth's atmosphere bombarded with the solar radiation commonly known as the northern lights. and how when come et cetera passed through the solar system, the tails were always away from the sun because, parker suspected, the solar wind blew them outward. but when he went to publish his formula, he was first met not with acclaim, but skorn. so, when you did this equation, and your critics said you should go back to the library and study something else, were they able to take anything apart in this? >> no, they simply declared the whole notion was ridiculous. and if you press them, they would say, well, you must have made a mistake here because you came to a ridiculous conclusion.

>> reporter: but nobody who said that was able to deconstruct this equation to prove it wrong. >> they didn't even try as far as i know. >> reporter: parker visited his name sake as it was readied for launch. he praised the people who designed all this, just as many of them consider him a science superstar. >> congratulations. >> thank you. >> reporter: the respect that has been shown to you is extraordinary. my favorite line, you'll you're like the brad pitt of astro physics. do you feel like brad fit? >> i'm not entirely clear who brad pitt is. >> reporter: well, let's just say he's very famous and really handsome. the 7-year $1.5 billion project will measure the speed of the solar winds. the sun may be the star within our reach. >> the sun is an ordinary star and if any of the star of the

same class will have the same features. >> reporter: does that mean that what we learn from this probe will tell us about all the stars in the galaxy? >> the majority of the stars in the galaxy. >> reporter: do you ever stop to think how you changed our vision of what the sun is? >> no, i never did actually. >> reporter: but even a hero astrophysicist who changed the way we see the stars -- >> here's the key to it. >> reporter: has his limits. when it comes to something closer to his earthly home, like his hometown, chicago cubs. easier to understand the sun than predict the outcome of a baseball game. >> absolutely. a baseball game is infinitely more complicated. how does this or that pitcher feel on the morning of the last game? i don't know. so far -- >> reporter: and as the solar probe begins its voyage, his lifetime voyage of discovery has
