NASA says researchers examined 37 galaxies and found less oxygen than simulations predicted.

- The study suggests winds driven by massive stars and supernovae eject oxygen from these galaxies.

Why it matters: NASA says the findings indicate galactic winds remove oxygen from low-mass galaxies more effectively than current models predict.
