On April 22, the Princeton University Geosciences Society (PUGS) organized a contingency of students and scientists to stand for science at the March for Science, Washington, D.C. They just happened to meet a few dinosaurs along the way.
With two suns in its sky, the planet Tatooine, home of Luke Skywalker, hero of the "Star Wars" films, is portrayed as an immense and parched desert. In real life, scientists know from observatories such as NASA's Kepler space telescope that two-star systems can support planets, but planets thus far discovered in double-star systems are large and gaseous. So the question remained: If an Earth-size terrestrial planet were orbiting two suns, could it support life?
Important dates to put on your calendar regarding the Geosciences spring program.
A study that used a new digital library and machine reading system to suck the factual marrow from millions of geologic publications dating back decades has unraveled a longstanding mystery of ancient life: Why did easy-to-see and once-common structures called stromatolites essentially cease forming over the long arc of earth history?
Using advanced modeling and simulation, seismic data generated by earthquakes, and one of the world’s fastest supercomputers, a team led by Jeroen Tromp of Princeton University is creating a detailed 3-D picture of Earth’s interior. Currently, the team is focused on imaging the entire globe from the surface to the core–mantle boundary, a depth of 1,800 miles.

Associate Research Scholar Dr. Maggie Lau has been selected as one of two recipients for the 2017 Deep Carbon Observatory (DCO) Emerging Leader Awards. Deep Carbon Observatory is a global research program with a goal to transform the understanding of what part carbon plays on planet Earth.
On March 17, 2017, The National Science Foundation (NSF) named 2,000 recipients of its Graduate Research Fellowship Program (GRFP).  Alumnus Ethan Campbell '16 was among the awardees.
Preston Cosslett Kemeny, a 2015 Princeton graduate, is one of 12 college seniors and first-year graduate students nationwide to be named 2017 Hertz Fellows by the Fannie and John Hertz Foundation.  Kemeny, who majored in geosciences and earned certificates in environmental studies and planets and life, is a graduate student in geochemistry in the Division of Geological and Planetary Sciences at the California Institute of Technology.
We know a lot about how carbon dioxide (CO2) levels can drive climate change, but how about the way that climate change can cause fluctuations in CO2 levels? New research from an international team of scientists reveals one of the mechanisms by which a colder climate was accompanied by depleted atmospheric CO2 during past ice ages.
