Flame Nebula: Hubble and Webb Observations (Compass Image)

Two images of the Flame Nebula (NGC 2024) at right, captured by Webb’s Near-Infrared Camera (NIRCam), with compass arrows, scale bar, and color key for reference. These images are magnified regions within the greater Flame Nebula, seen in the image at left captured by the Hubble Space Telescope.
The north and east compass arrows show the orientation of the image on the sky. Note that the relationship between north and east on the sky (as seen from below) is flipped relative to direction arrows on a map of the ground (as seen from above).
The scale bar is labeled in light-years, which is the distance that light travels in one Earth-year. (It takes 0.2 years, or about 2 and a half months, for light to travel a distance equal to the length of the bar.) One light-year is equal to about 5.88 trillion miles or 9.46 trillion kilometers. The field of view shown on the leftmost image is approximately 0.6 light-years across, and that of the rightmost image is approximately 0.4 light-years across.
The rightmost images show invisible near-infrared wavelengths of light that have been translated into visible-light colors. The color key shows which NIRCam filters were used when collecting the light. The color of each filter name is the visible light color used to represent the infrared light that passes through that filter.

Extended Description
Image titled “James Webb Space Telescope, Flame Nebula NGC 2024” with compass arrows, scale bar, and color key.
Image
A collage of three images showing a dusty nebula. The left two-thirds of the collage is taken up by an image of the nebula in visible light. The remaining third is taken up by two other images, one atop the other, in near-infrared. The visible light image has a pillar of dense brown dust running through the nebula at a diagonal from 5 o’clock to 11 o’clock. Wispy plumes appear to fly off from the pillar toward the sides amid blue clouds of the same material, which are whiter near the pillar. There are many white stars spread throughout. Two separate, white squares, tilted about 30 degrees, outline two areas in the pillar. The upper square has the letter “A” to the top right, while the lower square is marked by the letter “B”. These labels correspond to the two, magnified images of the nebula shown in near-infrared at right, with the top image also labeled “A” and the bottom image labeled “B”. Both images contain a mixture of reds, blues and browns, and show red, blue, and white stars.
Compass Arrows, Scale Bar, and Color Key
At the bottom left are compass arrows indicating the orientation of the image on the sky. The north arrow points in the 11 o’clock direction. The east arrow points toward 8 o’clock. At the lower right is a scale bar labeled 0.2 light-years. The length of the scale bar is about one-fifth the total width of the image. Below the image is a color key showing which NIRCam filters were used to create the image and which visible-light color is assigned to each filter. From left to right, NIRCam filters are: F115W and F140M are blue; F182M is green; F360M is orange; and F430M is red.

These images are a composite of separate exposures acquired by the James Webb Space Telescope using the NIRCam instrument and the Hubble Space Telescope using the UVIS/IR instrument. Several filters were used to sample specific wavelength ranges. The color results from assigning different hues (colors) to each monochromatic (grayscale) image associated with an individual filter. In this case, the assigned colors are: Left (Hubble)> Blue= F105W, Green= F130N, Red= F139M Right (Webb)> Blue= F115W + F140M, Green= F182M, Orange= F360M, Red= F430M
