Keith's note: As much as I loathe the overuse of the word "awesome" by Gen Y, the NASA Advisory Council took an informal vote during lunch break and asked me to post this video. Tip of the hat to NASA PAO. Direct link for those of you that have YouTube blocked by NASA.
Keith's update: A Carnegie astronomer notes: "While brimming with enthusiasm, this video makes a major error by claiming that JWST will be able "to see the Earth" if it was 25 light-years away. Sadly, this is not true. Here is what the JWST web page states is the true capability of JWST: "Webb can only see large planets orbiting at relatively large distances from the parent star. To see small Earth-like planets, which are billions of time fainter than their parent star, a space telescope capable of seeing at even higher angular resolution will be required. NASA is studying such a space mission, the Terrestrial Planet Finder." This quote is from the JWST web page located at: http://www.jwst.nasa.gov/faq.html#basic JWST will do fantastic science, but if someone says that it will do things that are impossible for it to do, the entire project is likely to suffer.
