First Light of the Universe?


Recommended Posts

NASA's Spitzer Space Telescope might have captured images of the first stars in the Universe, glimpsing an era more than 13 billion years ago; a time when the glow of the Big Bang faded. A 10-hour observation by Spitzer's infrared camera array in the constellation Draco captured a diffuse glow of infrared light. It's believed this glow is coming from the first stars, more than a hundred times more massive than our Sun, which survived for only a few million years before exploding as the first supernovae.
