SUMMARY: Bought a digital camera recently? It's probably got anywhere from 3.1 to 6 megapixels of resolution. Well, the European Space Agency is building a 1 gigapixel (a gigapixel is 1024 megapixels) digital camera for its upcoming Gaia space telescope, due for launch in 2010. It's actually not a single camera, but an array of 170. Gaia will be positioned 1.5 million km (930,000 miles) away from Earth, and will be designed to simultaneously photograph 1 billion stars and plenty of other celestial objects like asteroids, comets, galaxies, and nebulae. The goal will be to map the entire Universe down to a resolution one million times fainter than the human eye can see.
