X-ray image of the Chandra Deep Field-South, the region of the sky where the flaring X-ray source was discovered. This is the deepest X-ray image ever created, made with about 7 million seconds of observing time with NASA's Chandra X-ray Observatory. The location of the flaring source, named "CDF-S XT1," is marked with the white arrow. The series of small images along the bottom show the variability of the flaring X-ray source over time (with time increasing from left to right, spanning a period of a few hours).
