'Fingerprint' of earliest light in universe detected 00:46

(CNN)For millennia, humans have sat under a clear midnight sky and marveled at the spectacle emblazoned across the heavens. The stars seem eternal, as if they have always been there. But there's just one problem.
It isn't so.

The universe was once entirely dark, with nary a light anywhere throughout the entire cosmos. And then a single star burst into nuclear flame, sundering the void. Then another and another, leading to the stars and galaxies of the familiar universe. In what could well be a stunning breakthrough, a group of astronomers have announced that they have found radio signals that appear to provide evidence of the first stars to come into existence. And, just to add a bit of spice to the announcement, it's possible that they might have discovered dark matter, a hypothesized substance that has eluded discovery for decades.

Astronomer Avi Loeb, a professor at Harvard University, is quoted by the Associated Press as saying that "if confirmed, this discovery deserves two Nobel Prizes," one for observing the signal of the first stars and the other for detecting dark matter. He went on to conservatively point out that both claims are extraordinary and require extraordinary evidence. He urged caution.
