Summary[edit]

Description	Feel like you’re spiraling? You’re in good company! 🌀 The Webb telescope’s images of NGC 1433, NGC 7496 (this image) & NGC 1365 reveal the galaxies' networks of gas and dust in extraordinary detail. This data is part of an ongoing Webb survey of 19 spiral galaxies. Webb’s high-resolution infrared data fills in missing puzzle pieces, complementing the science from telescopes in other wavelengths. By aligning all of these data sets, the team will be able to accelerate new discoveries. Learn more and see all the images: www.nasa.gov/feature/goddard/2023/nasa-s-webb-reveals-int...

This image: This mid-infrared image of NGC 7496 was captured by Webb's MIRI. Image description: A gray, web-like spiral galaxy on a black background. Eight red diffraction spikes extend out from its extremely bright core. Colorful dots in the background represent background galaxies.

Image title	Scientists are getting their first look with NASA’s James Webb Space Telescope’s powerful resolution how the formation of young stars influences the evolution of nearby galaxies. The spiral arms of NGC 7496, one of a total of 19 galaxies targeted for study by the Physics at High Angular resolution in Nearby Galaxies (PHANGS) collaboration, arefilled with cavernous bubbles and shells overlapping one another in this image from Webb’s Mid-Infrared Instrument (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 they plow into.Until Webb’s high resolution at infrared wavelengths came along, stars at the earliest point of the lifecycle in nearby galaxies like NGC 7496 remained obscured by gas and dust. Webb’s specific wavelength coverage (7.7 and 11.3 microns), allow for the detection of polycyclic aromatic hydrocarbons, which play a critical role in the formation of stars and planets. In Webb’s MIRI image, these are mostly found within the main dust lanes in the spiral arms.In their analysis of the new data from Webb, scientists were able to identify nearly 60 new, undiscovered embedded cluster candidates in NGC 7496. These newly identified clusters could be among the youngest stars in the entire galaxy.At the center of NGC 7496, a barred spiral galaxy, is an active galactic nucleus (AGN). AGN is another way to refer to an active supermassive black hole that is emitting jets and winds. This glows quite brightly at the center of the Webb image. Additionally, Webb’s extreme sensitivity also picks up various background galaxies to NGC 7496, which appear green or red in some instances.NGC 7496 lies over 24 million years away from Earth in the constellation Grus.MIRI was contributed by ESA and NASA, with the instrument designed and built by a consortium of nationally funded European Institutes (The MIRI European Consortium) and NASA’s Jet Propulsion Laboratory, in partnership with the University of Arizona.
