Wired: The Moon used to spin on a different axis

1-nasadataleadWired reporter Emily Reynolds covered the research of SMU planetary scientist and research assistant professor Matthew Siegler and a team of scientists who discovered the moon wandered off its axis billions of years ago due to a shift in its mass most likely caused by volcanic activity.

The article, “The Moon used to spin on a different axis,” published March 24. A report on the discovery of the rare event was published today in Nature. Continue reading

NASA data leads to rare discovery: Earth’s moon wandered off axis billions of years ago

Ancient lunar ice indicates the moon’s axis slowly shifted by 125 miles, or 6 degrees, over 1 billion years. Earth’s moon is now a member of solar system’s exclusive “true polar wander” club, which includes just a handful of other planetary bodies. Planetary scientist Matt Siegler at Southern Methodist University, Dallas, and colleagues made the discovery while examining NASA data known to indicate lunar polar hydrogen. Continue reading
