Looking forward to the results. The telescope can detect infra red (which isn't affected by space dust) at a much higher resolution than before and will allow us to 'see' the atmospheres of planets of other nearby stars and possibly detect signs of life. Of particular interest is the TRAPPIST-1 system, a mere 39 light years away, where there are 7 planets, of which 3 are in the habitable zone (the right temperature for liquid water).

...I think the really big point about the James Webb Telescope being an infra-red telescope is that it will be able to see further back in time than the Hubble telescope. Looking deeper into space (further back in time) means looking at objects that are more and more red shifted, due to the expansion of the universe. Look far enough and they are red shifted right out of the spectral range of visible light telescopes such as Hubble. Hubble can only ever see so far back.

Launch postponed due to an anomaly:

NASA announced that the James Webb Space Telescope's launch was postponed to no earlier than December 22nd due to an incident that occurred during launch prep. The anomaly was due to a clamp band that shook the telescope unexpectedly.
