Young massive stars emit intense radiation and jets that carve cavities in gas clouds, either triggering new star formation or suppressing it by dispersing necessary materials. Stellar feedback is 100 times stronger in merging galaxies like NGC 3256 compared to normal spirals, constraining star clusters and creating high turbulence that affects disk formation.

Confidence
HIGH
Standard science journalism framing: research question → methodology → findings. Uses accessible analogies (e.g., 'stretching across the sky') to explain complex astrophysics without editorializing.
Potential limitations or criticisms of the study methodology
Alternative theoretical explanations for observed phenomena
Perspectives from researchers outside Ohio State or the PHANGS collaboration
Discussion of how findings compare to or challenge previous models
Impacto Geopolítico
