The binary star system, NGC 1333-IRAS2A, is surrounded by a disc consisting of gas and dust. Notably, the movement of gas and dust does not follow a continuous pattern. For relatively shorts periods of ten to one hundred years every thousand years the movement becomes very strong. The binary star becomes ten to one hundred times brighter, until it returns to its regular state. Credit From the scientific article by Jørgensen, Kuruwita et al.
