Caption: This is a simulated observation of a massive star viewed along the plane of the disk. This visualization of dust emission traces the density and temperature of the gas cloud that surrounds the star. The regions that are currently ionized (in red) and have been ionized in the past (blue structures) show how the nebula flickers.
