New Delhi: The European Space Agency is sending the $1.2 billion Gaia mission to space to catalog a billion stars, planets, asteroids and supernovas for generations of astronomers.
At the heart of the mission is a billion-pixel camera which will give scientists more clues about the origin and evolution of the universe, and in particular our own galaxy.
At approximately one billion pixels, it's the largest digital camera ever built for a space mission.
