Wow, that's quite a star lineup! I wish I could've been there too. Maybe next year...
And the quote of the night from the President, who said this in response to a young girl who was 14 when she discovered a supernova, and a high school sophomore who found a rare type of pulsar:
NASA's equipment is some pretty powerful stuff. But astronomy also depends on the curiosity and contribution of amateur astronomers. [...] If they can discover something great, so can any of you other students who are here tonight. All you need is a passion for science.
Damn straight. And awesome.
