The newest image from the James Webb Space Telescope shows a stunning display of dust and stars that form the bar of the barred spiral galaxy NCG 5068, located 17 million light-years away. Like our galaxy, the Milky Way, this galaxy has a central bar that is a more concentrated region of stars and dust compared to the arms that reach out from the galaxy’s center.
The image was taken using two of Webb’s instruments, the Mid-Infrared Instrument and the Near Infrared Camera . By looking in both the mid- and near-infrared wavelengths, Webb is able to pick out features like the swirls of dust and gas, as well as the stars in this region, with the bar of the galaxy glowing in the top left of the image.
The bar of a barred spiral galaxy is typically a busy region of star formation, so this image was collected as part of a study into star formation in nearby galaxies. The Physics at High Angular resolution in Nearby GalaxieS project involves both Webb and the Hubble Space Telescope, along with other ground-based telescopes like the Very Large Telescope and the Atacama Large Millimeter/submillimeter Array, and is a survey to take high-resolution images like this one of regions of star formation.
Related For this project, “Webb collected images of 19 nearby star-forming galaxies, which astronomers could then combine with catalogs from Hubble of 10,000 star clusters, spectroscopic mapping of 20,000 star-forming emission nebulae from the Very Large Telescope , and observations of 12 000 dark, dense molecular clouds identified by the Atacama Large Millimeter/submillimeter Array ,” Webb scientists write.
Recommended Videos Webb is particularly useful for studying star formation, because it looks in the infrared wavelengths. This allows its instruments to see through clouds of dust, which would be opaque in the visible light wavelength. In the image above, you can see the dust forming a green web-like structure between the stars, which glow as points of light. Bubbles of gas are shown in red.
