Largest Space Telescope ever built by Human

The James Webb Space Telescope is three stories tall, as wide as a tennis court. It’s got a 21-foot primary mirror and then it’s got these 4 instruments that are just incredibly powerful. It’s the largest, most technologically challenging space telescope ever created. It’s designed to look back in time even further than Hubble to see the very first galaxies to form after the Big Bang.

NASA stands for National Aeronautics and Space Administration. NASA was started on October 1, 1958, as a part of the United States government. NASA is in charge of U.S. science and technology that has to do with airplanes or space.
