NASA Finds Lunar Regolith Limits Meteorites as Source of Earth’s Water
NASA Finds Lunar Regolith Limits Meteorites as Source of Earth’s Water NASA has found that lunar regolith limits meteorites as a source of Earth’s water, suggesting that late delivery of water-rich meteorites was not the dominant source of Earth’s oceans. The study used a novel method to analyze the dusty debris on the Moon’s surface […]

Percolating Clues: NASA Models New Way to Build Planetary Cores
Percolating Clues: NASA Models New Way to Build Planetary Cores NASA has discovered a new way planetary cores may have formed, challenging the long-held belief that large-scale melting was necessary for core formation. The study suggests that molten sulfide could percolate through solid rock and form a core, even before a planet’s silicate mantle begins […]
