Herbig-Haro 49/50 (Spitzer and Webb Images)
About This Image
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.

About The Object
- Object Name
- A name or catalog number that astronomers use to identify an astronomical object.
- Object Description
- The type of astronomical object.
- R.A. Position
- Right ascension – analogous to longitude – is one component of an object's position.
- Dec. Position
- Declination – analogous to latitude – is one component of an object's position.
- Constellation
- One of 88 recognized regions of the celestial sphere in which the object appears.
- Distance
- The physical distance from Earth to the astronomical object. Distances within our solar system are usually measured in Astronomical Units (AU). Distances between stars are usually measured in light-years. Interstellar distances can also be measured in parsecs.
