ESA/Webb published a Picture of the Month showing two dwarf galaxies, NGC 4490 and NGC 4485, locked in a gravitational interaction.
The pair offers a nearby laboratory for studying how galaxy encounters reshape gas, dust and star formation.
The technology story is Webb's infrared sensitivity, which helps reveal star-forming structure through dusty regions that visible-light views can miss.
Why It Matters
Interacting dwarf galaxies help astronomers understand how smaller galaxies evolve and trigger new star formation.
What to Watch
Watch follow-up infrared studies and comparisons with Hubble visible-light images.
