This illustration shows a likely configuration of a gravitational lensing system discovered by the team: the milli-lens is located in or near the intervening spiral galaxy; the lens is magnifying blobs of jet material within the active galaxy PKS1413+135, but the blobs are too small to be seen in the radio image (top left); only when the blobs move far away from the yellow core do they expand and are visible as the pink blobs in the image.
