On Christmas Day, NASA is launching into space its biggest, most expensive and most powerful telescope yet.
The James Webb Space Telescope will rocket into the cosmos and orbit nearly 1 million miles away from Earth.
If the launch is successful, the telescope will spend five to 10 years studying the formation of the universe’s earliest galaxies, how they compare to today’s galaxies, how our solar system developed and if there is life on other planets.
ABC News explains how the telescope works, how it compares to its predecessor -- the Hubble Telescope -- and what needs to happen for the mission to go just right.
