10 billion years ago, our sky was full of stars being born
Light pollution and city living mean that we don’t often get to enjoy the full splendor of the night’s sky. Ten billion years ago, however, it would have been hard to ignore. The image above shows how the night’s sky would have looked 10 billion years ago during our galaxy’s “baby boom” phase.
At the time, the Milky Way was producing stars at an phenomenal rate — 30 times faster than it is today. The pink clouds in the image are the interstellar nurseries of gas and dust, while the blue and white points of light are the newly formed stars. If this was a real picture, however, some of stars, newborn 10 billion years ago, would already be extinguished today.
