... This is a false color image of HR 4796A composed of visible and near-IR light (blue=STIS, green=1.71 micron, red=2.22 micron). It's red color is caused by dust grains that scatter light poorly in the visible and very efficiently in the near-IR. This images shows the debris disk around HD 61005, and a model of debris disk dust grains being blown by and interstellar wind. This work was a Goddard web feature (look there for a cool movie showing one of the models). ...
