It is a replacement for the [[Hubble Space Telescope]] which was launched in 1990.<ref>{{cite web|title=James Webb Space Telescope|url=http://www.jwst.nasa.gov/|publisher=NASA|accessdate=14 May 2013}}</ref> The telescope is named after [[James E. Webb]], who was a director at [[NASA]] and created the [[Apollo program]] that put astronauts on the moon. It has a main mirror that is {{convert|6.5|m|ft|abbr=off}} wide. This is 6 times larger in area than Hubble. It is so large that it is made in 18 pieces that fold together during the launch, so that it can fit into a rocket. It is mainly an [[infrared telescope]] but also works in the red part of the visible light (the pictures will be coded with [[false color]] so we can see them). It is plated with gold because [[gold]] reflects infrared very well. It is able to see things that the Hubble Space Telescope cannot. [[Infrared]] vision can be used to see heat radiation (like some kinds of [[night vision]] goggles), so the telescope itself must be kept as cool as possible. It is protected by a large sunshield the size of a [[tennis court]] to keep it cool and dark. NASA released [[Webb's First Deep Field|the first image from JWST on 11 July 2022]], the oldest and highest resolution image of the Universe.<ref>{{Cite web |last=Dunbar |first=Brian |date=2022-06-08 |title=First Images from the James Webb Space Telescope |url=http://www.nasa.gov/webbfirstimages |access-date=2022-07-11 |website=NASA}}</ref> ==Orbit== [[File:JWST-at-L2-Lagragian-Point.jpg|thumb|JWST orbit (not to scale)]] The JWST
