Caption
This side-by-side comparison shows a Spitzer Space Telescope image of HH 49/50 (left) versus a Webb image of the same object (right) using the NIRCam (Near-infrared Camera) instrument and MIRI (Mid-infrared Instrument). The Webb image shows intricate details of the heated gas and dust as the protostellar jet slams into the material. Webb also resolves the “fuzzy” object located at the tip of the outflow into a distant spiral galaxy.
The Spitzer image shows 3.6-micron light in blue, the 4.5-micron in green, and the 8.0-micron in red. In the Webb image, blue represents light at 2.0-microns (F200W), cyan represents light at 3.3-microns, green is 4.4-microns, orange is 4.7-microns, and red is 7.7-microns.
