Evidence from the fragments of a destroyed asteroid suggests that the shift in the positions of the giant planets in our solar system billions of years ago happened between 60–100 million years after the solar system's ...
While the upcoming total solar eclipse is a special moment to reflect on our place in the universe, scientists have been studying the birth of the sun and the formation of our solar system for a long time.
How Earth and the other planets of the solar system formed and evolved over the eons is a hot question for planetary scientists like me. One of the best ways to find out is by looking at rocks from space.
Three physicists have taken a new look at the circumstances surrounding the mysterious Chinguetti meteorite and developed a means for confirming whether it exists or not. In their paper posted to the arXiv preprint server, ...
CU Boulder geologist Brian Hynek has helped to document what may be a unique kind of ecosystem on Earth—and a possible window into the earliest stages of life on this planet 3.5 billion years ago, and even life on ancient ...
What wiped out the dinosaurs? A meteorite plummeting to Earth is only part of the story, a new study suggests. Climate change triggered by massive volcanic eruptions may have ultimately set the stage for the dinosaur extinction, ...
Dr. Alice Stephant, an astrophysicist, is helping to solve a longstanding mystery about water on Earth: where it came from.
More than 4 billion years ago, when the solar system was still young and the Earth was still growing, a giant object the size of Mars crashed into the Earth. The biggest piece that broke off of the early Earth formed our ...
To help resolve the scientific debate over whether it was a giant asteroid or volcanic eruptions that wiped out the dinosaurs and most other species 66 million years ago, Dartmouth researchers tried a new approach—they ...
Meteorites—fragments of rock that have fallen to Earth from space in spectacularly fiery meteors—have been the subject of public fascination, awe, myths and even religious worship for thousands of years.
