The Moon's Interior Isn't What We Thought: Blue Ghost Data Upends Fifty Years of Thermal Models
1+ mon, 5+ day ago (540+ words) Firefly Aerospace's Blue Ghost lander spent time on the lunar surface in early 2025, and the data it sent back may force scientists to redraw one of the oldest maps of the moon's internal structure. That sounds like a technical detail....
Seafloor weathering may explain ancient global glaciation puzzle
2+ mon, 1+ week ago (799+ words) New York (SDX) Feb 25, 2026 - In Earth history, a few episodes stand out for their extreme cold, when geologic evidence indicates that ice covered the planet from pole to pole during so-called Snowball Earth events. These episod Seafloor weathering may explain…...
