Recently, the international team ALMA Survey of Orion Planck Galactic Cold Clumps (ALMASOP) led by Prof. Liu Tie from Shanghai Astronomical Observatory (SHAO) of the Chinese Academy of Sciences conducted a high-resolution investigation on 72 dense cores in the Orion Giant Molecular Clouds (GMCs) with the Atacama Large Millimeter/submillimeter Array (ALMA), and discovered a forming quadruple-star system within one core. The result of ALMA observation also revealed ribbon-like dust structures and intricate molecular outflows.
