More than 400 million years ago, an upwelling of hot rock from the Earth’s mantle caused the crust in Mongolia to split apart, creating an ocean that lasted for 115 million years. The geologic history of this ocean could help researchers understand Wilson cycles, or the process by which supercontinents break apart and reassemble. These … Read more

Our planet was born about 4.5 billion years ago. To understand this mind-bogglingly long history, we must study rocks and the minerals from which they are made. The oldest rocks in Australia, which are among the oldest on Earth, are found in the Murchison District of Western Australia, 700 kilometers north of Perth. They have … Read more

UNIVERSITY PARK, PA — The earth beneath our feet can feel solid, stable, and seemingly eternal. But the continents we call home are unique among our planetary neighbors, and their formation has long been a mystery to scientists. Now researchers think they may have uncovered a crucial piece of the puzzle: the role of ancient … Read more
On September 29, 2022, NASA’s Juno spacecraft made its closest flyby of Europa, coming within 355 kilometers of the frozen surface of Jupiter’s moon. The close-up view of Europa revealed incredible details of the moon’s chaotic terrain, suggesting the icy crust is not where it once was. The images also showed a newly discovered feature … Read more
