The world's largest and most powerful space telescope rocketed away Saturday on a high-stakes quest to behold light from the first stars and galaxies and scour the universe for hints of life.
NASA's James Webb Space Telescope soared from French Guiana on South America's northeastern coast, riding a European Ariane rocket into the Christmas morning sky.
The $10 billion observatory hurtled toward its destination 1 million miles away, or more than four times beyond the moon. It will take a month to get there and another five months before its infrared eyes are ready to start scanning the cosmos.

Facing the dark side of Earth, away from the Sun, the telescope will observe the early universe going as far back as the big bang itself.
Intended as a successor to the aging Hubble Space Telescope, the long-delayed James Webb is named after NASA's administrator during the 1960s. NASA partnered with the European and Canadian space agencies to build and launch the new 7-ton telescope, with thousands of people from 29 countries working on it since the 1990s.
