James Webb Telescope Model at SXSW

As big as a tennis court and as tall as a four-story building, NASA's James Webb Space Telescope is the successor to Hubble and the largest space telescope to ever be built. A full-scale model was on display from March 8-10 at the South by Southwest Interactive Festival in Austin, Texas.
