Do you have a science-related inquiry burning a hole in your brain that you've always wanted to ask someone really, really smart? You're in luck!

Big Think's amazing audience responded so well to our first round of videos from NASA astronomer and Assistant Director for Science Communication Michelle Thaller that we couldn't wait to bring her back for more! 


And this time, she's ready to tackle any questions you're willing to throw at her, like, "How big is the Universe?", "Am I really made of stars?" or, "How long until Elon Musk's Tesla leaves the solar system?"

All you have to do is submit your questions to the form below, and we'll use them for an upcoming Q+A session with Michelle. You know what to do, Big Thinkers!
