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. Continue reading
Science reporter Danny Lewis with Smithsonian 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, “Ancient Volcanoes May Have Shifted the Moon’s Poles,” published March 24. A report on the discovery of the rare event was published today in Nature: that Earth’s moon slowly moved from its original axis roughly 3 billion years ago. Continue reading
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
SMU graduate and undergraduate students presented their research to the SMU community at the University’s Research Day 2016 on Feb. 10.
SMU scientists and their research have a global reach that is frequently noted, beyond peer publications and media mentions.
It was a good year for SMU faculty and student research efforts. Here’s a small sampling of public and published acknowledgements during 2015, ranging from research modeling that made the cover of a scientific journal to research findings presented as evidence at government hearings. Continue reading
Science Insider, the online news site for the American Association for the Advancement of Science, quoted SMU seismologist Brian Stump, saying seismic data confirms that an earthquake in North Korea was triggered by an explosion there Jan. 5.
Science journalist Anna Kuchment with The Dallas Morning News covered the comments of SMU seismologists Heather DeShon and Beatrice Magnani speaking during the annual American Geophysical Union meeting in San Francisco, Calif.
DeShon and Magnani presented their latest research on North Texas ground shaking. Continue reading
The researchers calculated the new measurement for a critical characteristic — mass — of the Top Quark. The new value adds growing uncertainty to physics’ Standard Model. Continue reading
Initial data from a new U.S.–based physics experiment indicates scientists are a step closer to understanding neutrinos, the second most abundant particle in the universe, says SMU physics professor Thomas Coan, a principal investigator on the project.
Neutrinos are little understood, but indications are they hold clues to why matter overwhelmingly survived after the Big Bang instead of just energy in the form of light. Continue reading
