Earth's moon wandered off axis billions of years ago
by Staff Writers
Dallas TX (SPX) Mar 24, 2016 A new study published in Nature reports discovery of a rare event - that Earth's moon slowly moved from its original axis roughly 3 billion years ago. Planetary scientist Matt Siegler at Southern Methodist University, Dallas, and colleagues made the discovery while examining NASA data known to indicate lunar polar hydrogen. The hydrogen, detected by orbital instruments, is presumed to be in the form of ice hidden from the sun in craters surrounding the moon's north an ... read more
