Artist's impression of the large-scale view of FU~Ori

Artist's impression of the large-scale view of FU~Ori. The image shows the outflows produced by the interaction between strong stellar winds powered by the outburst and the remnant envelope from which the star formed. The stellar wind drives a strong shock into the envelope, and the CO gas swept up by the shock is what the new ALMA revealed. Image credit: NSF/NRAO/S. Dagnello
