2639 - World's biggest, most powerful telescope launched into space by NASA

NASA has launched James Webb Space Telescope, the world's largest and most powerful space telescope, atop a European Ariane 5 rocket from South America's French Guiana. The $10-billion telescope, which is 100 times more powerful than its predecessor Hubble, will orbit 1.5 million kilometres away from Earth. It's designed to observe the very first galaxies formed 13.5 billion years ago.
