If confirmed, the observation provides a glimpse of an era more than 13 billion years ago when, after the fading embers of the theorized Big Bang gave way to millions of years of pervasive darkness, the universe came alive."

I think 'light' is a broadly applied term here, and fact is, the method they used was to measure cosmic radiation, and subtract from it the radiation levels of known galaxies to arrive at an amount that "must" be leftover from stars long past.

This CNN article [cnn.com] put it best: "The exercise was like taking a recording of a stadium full of loud people and subtracting the noise of every person except one to hear the voice of that single individual."
