NASA Reopens Comet-Water Debate

NASA's new study reveals that Comet 103P/Hartley 2 mirrors Earth's water molecular signature, suggesting Jupiter-family comets might've helped flood our planet. This shakes off previous skepticism from Comet 67P’s mismatched ratios. Released on December 5, 2024, the research highlights Kuiper Belt comets' potential role in Earth's watery origins, sparking fresh debates. Meanwhile, meteorites and elusive dark comets continue to stir the cosmic conversation, proving space still loves to keep us guessing.
