World's biggest space telescope launched to discover early cosmic history

NASA's James Webb Space Telescope (JWST), the world's biggest, most complex and most powerful space telescope ever built, was launched on Saturday. The telescope was sent into space by an Ariane 5 rocket from Europe's Spaceport in Kourou, French Guiana, after several delays caused by technical glitches. The $10 billion observatory hurtled toward its destination one million miles (1.6 million kilometers) 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.
