NASA's $8.7 Billion James Webb Space Telescope Will Help Unlock The Universe's Secrets

The Hubble Space Telescope that has been orbiting Earth since 1990, has and continues to reveal secrets of planets, stars, and galaxies that lie trillions of miles away. In 2018, it will finally be retired and replaced by the larger, and more powerful, James Webb Space Telescope (JWST). The announcement, made by NASA on November 2, culminates a 20-year quest to build a state of the art telescope that cost $8.7 billion and required the construction of new assembly and testing facilities.
