This is how colossal NASA's new Hubble Space Telescope successor is

In a cavernous Los Angeles County cleanroom, Northrop Grumman and NASA engineers have pieced together the space agency’s prized next-generation telescope, the James Webb Space Telescope.

It’s big. 

How big? NASA tweeted a picture of a human standing on a crane beside the behemoth cosmic-sleuthing satellite, for reference. 

(Human for scale.)

This photo showcases just how big #NASAWebb is! We’ll be sharing more behind-the-scenes images captured during the integration of the spacecraft and telescope halves of the observatory in this thread.
