2.12 µm molecular hydrogen emission at DR21 overlaid with CO (2−1) emission (white dots) of the explosive outflow. The H2 emission was obtained using the Apache Point Observatory 3.5 meter telescope and NICFPS near-infrared camera using a 0.5 bandpass filter (PI: John Bally). The yellow square is the center of the outflow. The dashed blue lines trace arc-shaped structures detected in H2.
