Reporter Rachel Feltman at The Washington Post 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. The article, "Volcanic activity may have shifted the moon’s axis," published March 23. A report on the discovery of the rare event was published today in Nature.
There’s nothing subtle about the story told by the rocks in northern Italy’s Sesia Valley. Evidence of ancient volcanic activity is all around, says geologist and volcanologist James Quick, Southern Methodist University, Dallas. But the full story is much less obvious, said Quick, who led an international team that in 2009 announced they had discovered a 282-million-year-old fossil supervolcano in Sesia Valley.
