A young star at the apex of McNeil's Nebula was observed to brighten dramatically in X-ray, optical and infrared wavelengths, illuminating the nebula. The X-ray data are strong evidence that the probable cause of the outburst is the sudden infall of gas onto the surface of the star from an orbiting disk of gas. Accumulation of more gas in the disk could lead to a new outburst in the future. This scenario could explain why the brightness of McNeil's Nebula appears to vary with time.
