FINDING THE ASHES OF THE FIRST STARS
Hubble zooms on the sky (0:39)
A new observation by the Earth-orbiting NASA/ESA Hubble Space Telescope has profound implications for the understanding of the earliest years of our Universe.
A team led by the astronomer Wolfram Freudling has revealed that the first stars in the Universe were formed only 200 million years after the Big Bang. Several hundred million years earlier than previously thought.
The team used Hubble's infrared instrument NICMOS to observe light from some of the most distant, exotic and ultra-luminous sources known to mankind: quasi-stellar objects, sometimes known as quasars.
Hubble's position above the atmosphere allows it to observe infrared light normally obscured by the Earth's atmosphere and unavailable to Earth-bound telescopes.
