Decomposition of gas (IMAGE) Royal Astronomical Society Caption WEAVE decomposition of gas in Stephan's Quintet, overlaid on a JWST image. The red highlights gas shocked by the collision, while green and blue shows star-forming regions. The purple areas represent bubbles with an unknown origin. The black contours show neutral Hydrogen, and its location relative to the shocked gas (in red) suggests that is where it comes from.
