Watch the James Webb Space Telescope Assemble
The James Webb Space Telescope is on track to meet its fast approaching launch date of October 2018  with the final assembly of its primary mirror segments, finished this February. 
This mirror assembly, which measures a total of 6.5 meters across (over 24 feet), will make the JWST the largest space telescope ever launched and will allow it to peer further back to the edge of time and space than even the Hubble. They will also give the JWST incredible views of objects nearer to us as well, being able to observe objects in our own solar system, our stellar neighborhood, and even planets around other stars. It will be able to accomplish these stunning observations by using its large mirror assembly to peer deep into the infrared spectrum of light, allowing the JWST to pick out faint objects invisible to visible light telescopes.
You can actually watch live as the engineers and technicians peice together the James Webb Space Telescope using the JWST's WEBB CAM. Check out the precision action at

Dr. Milam held an informative and fun chat with NSN members about observing solar system objects with the James Webb Space Telescope, and hosted a lively QA at the end with members. You can find the video of the talk, along with additional questions answered by Dr. Milam post-talk and links to more information about the JWST, on our resource page.
The Night Sky Network has also developed some great materials to help audiences at outreach events understand more about the special properties of space telescopes.You can find out why we put telescopes in space with our special PowerPoint and related activities. here: 

Also, did you know that telescopes help us glimpse into the past? Find out about how telescopes are time machines here:

You can also watch a great, detailed video of what happens after the JWST is launched and how it will deploy once it attains its orbit. Check it out on YouTube at
