SEPTEMBER-OCTOBER2026 vealed large scale structures in the infraredwithoutresolvingindivid-ual stars. Now, Webb brings both clarity and depth, exposing the galaxy’s inner workings star by star. “No single telescope tells the whole story,” said Shawn Domagal-Gold- man,divisiondirector,Astrophysics, NASA Headquarters in Washington. “Discoveries build over time andnew observatories expand on the foundations laid by earlier missions. Webb represents the most powerful step forward yet, opening a window into wavelengths and details never beforeaccessible.Thisallowsas- tronomers to examine structuresand processes that other telescopes could not see.” Webb’s mid-infrared vision high- lights the galaxy’s rich dust struc- tures,whichglowinintricateshapes that surprise and even perplex as- tronomers. A warped, parallelo- gram-like band cuts across the gal- axy’scenter,whilewispsofmaterial stretch outward like cosmic clouds. An “S” shaped feature, most no- table in the image from Webb’s MIRI (Mid-InfraredInstrument),isalsoun- usual and invites questions thatneed further study to answer.
