has captured images of three nearby galaxies with unprecedented resolution at infrared wavelengths, giving them a first look at star formation, gas and dust.
Data has enabled researchers to pen 21 research papers, providing new insight into how the beginnings of star formation impact the evolution of galaxies. The data is part of an ongoing Webb survey of 19 spiral galaxies and observations of five of those targets have taken place. The images from Webb's Mid-Infrared Instrument, or MIRI, reveal the presence of highly-structure features, including glowing cavities of dust and huge cavernous bubbles of gas that line the spiral arms.
The spiral arms of NGC 7496 are filled with cavernous bubbles and shells overlapping one another in this image from MIRI. These filaments and hollow cavities are evidence of young stars releasing energy and, in some cases, blowing out the gas and dust of the interstellar medium surrounding them.
The team of more than 100 researchers from around the globe will work to create and release data sets that align Webb's findings to that obtained previously from other observatories. In the MIRI observations of NGC 1365, clumps of dust and gas in the interstellar medium have absorbed the light from forming stars and emitted it back out in the infrared, lighting up an intricate network of cavernous bubbles and filamentary shells influenced by young stars releasing energy into the galaxy’s spiral arms.
