US scientists have found two interstellar clouds of original gas, which contain only original elements created moments after the universe's birth.
Unlike everything else in the universe — the gas clouds have never mingled with elements forged later in stars.
The existence of pristine gas that formed minutes after the Big Bang explosion some 13.7 billion years ago, had been predicted, but never before observed.
