NASA finds Comet 67P's water similar to Earth's, suggesting comets may have delivered Earth's water.
NASA researchers have found that Comet 67P/Churyumov-Gerasimenko has water similar to that in Earth's oceans, suggesting comets may have delivered water to Earth.
Previous studies showed high deuterium levels in the comet's water, but new analysis indicates that cometary dust skewed these measurements.
This discovery could change our understanding of Earth's water origins and the early solar system's composition.
