NGC 604 (MIRI Image)

At the center of the image is a nebula on the black background of space. The nebula is comprised of wispy filaments of light blue clouds. At the center-right of the blue clouds is a large cavernous bubble. The bottom left edge of this cavernous bubble is filled with hues of pink and white gas. There are several other smaller cavernous bubbles at the top of the nebula, including two tiny cavities at the top center of the image. There are hundreds of dim stars that fill the surrounding area of the nebula.

This image from NASA’s James Webb Space Telescope’s MIRI (Mid-Infrared Instrument) of star-forming region NGC 604 shows how large clouds of cooler gas and dust glow in mid-infrared wavelengths. This region is a hotbed of star formation and home to more than 200 of the hottest, most massive kinds of stars, all in the early stages of their lives.

In the MIRI view of NGC 604, there are noticeably fewer stars than Webb’s NIRCam image. This is because hot stars emit much less light at these wavelengths. Some of the stars seen in this image are red supergiants—stars that are cool but very large, hundreds of times the diameter of our Sun. The blue tendrils of material signify the presence of polycyclic aromatic hydrocarbons, or PAHs.

At the center of the image is a nebula on the black background of space. The nebula is comprised of wispy filaments of light blue clouds. At the center-right of the blue clouds is a large cavernous bubble. The bottom left edge of this cavernous bubble is filled with hues of pink and white gas. There are several other smaller cavernous bubbles at the top of the nebula, including two tiny cavities at the top center of the image. There are hundreds of dim stars that fill the surrounding area of the nebula.
Color Info
Color InfoA brief description of the methods used to convert telescope data into the color image being presented.

This image is a composite of separate exposures acquired by the James Webb Space Telescope using the NIRCam instrument. Several filters were used to sample varying 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:  Luminostiy: F335M, Blue: F700W, Green: F1130W, Red: F1500W

At the center of the image is a nebula on the black background of space. The nebula is comprised of clumpy, red, filamentary clouds. At the center-right of the red clouds is a large cavernous bubble, and at the center of the bubble there is an opaque blueish glow with speckles of stars. At the edges of the bubble, the dust is white. There are several other smaller cavernous bubbles at the top of the nebula, including two tiny cavities at the top center of the image. There are thousands of stars that fill the surrounding area outside the nebula, most of them are yellow or white. At 11 o’clock and 6 o’clock there are extremely bright stars with 8 diffraction spikes. There are also some smaller, red stars and a few disk-shaped galaxies scattered across the image.
