Set to launch on Christmas Eve, the James Webb Space Telescope (JWST) promises to revolutionize our understanding of the cosmos by enabling scientists to look further back in time than ever before.

The telescope, which was first proposed in 1989 and thus far has cost about $10 billion, will have the ability to stare deeper into space than previous telescopes. This is thanks to its 6.5-meter light-gathering primary mirror, which is almost three times the size of that of the Hubble Space Telescope.
