The most powerful and most expensive telescope ever made was launched into space on December 25. The James Webb Telescope is considered to be the most significant science breakthrough in the history of humankind. Just about a month after launch, this 10-billion dollar observatory reached the point in space called L2 from which it will be able to provide some of the most magnificent pictures of space.
Still, why did NASA spend so much money on this telescope and how is it different from the previous models such as the Hubble?
