English: This is an artist's impression of two young binary stars that may be the source of mysterious regular bursts of light from the object called LRLL 54361 that lies inside the star-forming region IC 348, located 950 light-years away. Astronomers speculate that the flashes are due to material in a circumstellar disk suddenly being dumped onto the growing young stars and unleashing a blast of radiation each time the stars get close to each other in their orbit.
