Herbig-Haro 49/50 (Spitzer and Webb Images)

A side-by-side comparison of a Spitzer infrared image of Herbig-Haro 49/50 (HH 49/50) (left) versus a Webb infrared image (right) of the same object. In Spitzer’s view of the cone-shaped nebula with tornado-like features shows rainbow colors in shades of blue at tip, changing into green hues then orange hues down the cone towards the lower right. The background is punctuated with white small galaxies. A round blur with a blue core and reddish halo appears at the tip of the cone. The Webb view of HH 49/50 is dominated with shades of orange-red colors, rich in details throughout the cone-shaped nebula. The round blur at the tip of the nebula is resolved into spiral galaxy. The galaxy has a concentrated blue center that fades outwards to blend in with red spiral arms. The black background speckled with some white stars and smaller, fainter, and more detailed white galaxies.

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.

Angled from the upper left corner to the lower right corner is a cone-shaped orange-red cloud known as Herbig-Haro 49/50. This feature takes up about three-fourths of the length of this angle. The upper left end of this feature has a translucent, rounded end. The conical feature widens slightly from the rounded end at the upper right down to the lower right. Along the cone there are additional rounded edges, like edges of a wave, and intricate foamy-like details, as well as a clearer view of the black background of space. In the upper left, overlapping with the rounded end of Herbig-Haro 49/50, is a background spiral galaxy with a concentrated blue center that fades outward to blend with red spiral arms. The background of space is speckled with some white stars and smaller, more numerous, fainter white galaxies throughout.

Herbig-Haro 49/50 (NIRCam and MIRI Image)

NASA’s James Webb Space Telescope observed Herbig-Haro 49/50, an outflow from a nearby still-forming star, in high-resolution near- and mid-infrared light. The young star is off to the lower right corner of the Webb image.Intricate features of the outflow, represented in...

Image titled “James Webb Space Telescope; Stellar Jets; Herbig-Haro 49-50,” with compass arrows and color key. In the center is a cone-shaped orange-red cloud known as Herbig-Haro 49/50. At the end of the cone there is background spiral-shaped galaxy with a concentrated blue center that fades outwards to blend in with red spiral arms. At the bottom left is a scale bar labeled 0.05 light-years. The length of the scale bar is about one sixth of the total image. At the bottom right are compass arrows indicating the orientation of the image on the sky. The east arrow points toward 2 o’clock. The north arrow points in the 5 o’clock direction. Below the image is a color key showing which NIRCam and MIRI filters were used to create the image and which visible-light color is assigned to each filter. From left to right: F200W is blue, F335M is cyan, F444W is green, F470N is orange, and F770W is red.
