In a galaxy of a billion stars, unknown luminaries and unchartered spheres, humans only seem to be a tiny, barely recognisable spark within the infinity of the universe. The question of how the universe came about has been asked since the year dot. We know of the Big Bang theory, but what really lies behind it all? NASA is discussing this question in cooperation with the European and Canadian space agency. The James Webb Space telescope, a giant golden mirror, is now taking a big step in the endeavour to explore the universe. Not only is the infrared telescope supposed to investigate the beginning of our universe and the genesis of our planetary system, but it will also be deployed in the search for exoplanets and the feasibility of life on them. Lee Feinberg, Optical Telescope Element Manager at NASA, talks to us about the work behind the cosmic project.
