James webb Definition and 13 Threads

In case you didn't see it elsewhere:

Maybe this is more general discussion, but I am excited / nervous about the upcoming launch of the JWST. https://jwst.nasa.gov/content/webbLaunch/countdown.html I can't wait to see the observations this endeavor will bring!

Apparently, one of the solar arrays on the Lucy spacecraft failed to fully deploy. https://scitechdaily.com/nasas-lucy-stable-in-cruise-mode-problematic-solar-array-is-75-to-95-deployed/ The fault may not be fatal. They may have enough solar power to complete the mission. At the same time...

The Hubble Telescope helped us to see how enormous the universe really is. We now know from data built up from that that the universe likely has 2 trillion galaxies in it. Now when James Webb gets out their and starts taking better pictures; I’m afraid the count of galaxies will jump to 10 or...

James Webb Space Telescope launch and deployment sequence

Time-lapse video of two dozen engineers and technicians successfully installing the package of science instruments of the James Webb Space Telescope into the telescope structure.

Does JWST has any significance in fundamental physics research? What kind of questions would we get answers to?

What are the differences between these telescopes and which telescope will do more for our understanding of the universe? I know that ALMA is a series (66) radio telescopes, however, it also operates with optical telescopes. James Webb is an infrared telescope.

Will the James Webb telescope be able to see beyond the Big Bang in principal? I realize, in reality this is not possible, but I'm curious if it will see as far back as possible, or if the telescope has limits, and eventually we will need a better telescope to truly look deep. Thanks!

Our Universe is 13.5 Billion Years old approximately. Till now Hubble telescope has discovered galaxy at 13.2 billion light-years ago. Is it possible for James Webb Telescope to discover object or galaxy prior to 13.5 Billion Years old?

Or it might as well be, the result would be the same. Dennis Overbye in the NY Times: http://www.nytimes.com/2011/07/07/science/07webb.html" According to this article (found on http://en.wikipedia.org/wiki/James_Webb_Space_Telescope" ), the project cost ballooned from $1.6 billion to a current...

NASA have definitelly chosen the primary mirror for the JWST. It will be a berylium-based mirror. The JWST will be launched in 2011 to replace the Hubble www.universetoday.com/am/publish/james_webb_mirror_approved.html Woa! I can't wait til then!
