Search for Extra-Terrestrial Life Takes Mars Scientists on Expedition to Australia
As any geologist worth his or her salt will tell you, there are rocks, and then there are rocks. Next July, NASA and the European…

Did an extraterrestrial impact trigger the extinction of ice-age animals? University of South Carolina archaeologist finds evidence in South Carolina to support controversial theory. A…
Giant ridges on the surface of landslides on Mars could have formed without ice, challenging their use by some as unequivocal evidence of past ice…
Fossil remains of tiny calcareous algae not only provide information about the end of the dinosaurs, but also show how the oceans recovered after the…
Primordial chemical signatures discovered in modern kimberlites trace back 2 billion years. Scientists have detected primordial chemical signatures preserved within modern kimberlites, according to new…
Curtin University researchers have discovered that a global ice age more than 600 million years ago dramatically altered the face of the planet, leaving a…
The geode of Pulpí is an 11-meter (36-foot) hollow ovoid with crystal-paneled walls. It is like those familiar couplets of stone interiors covered with bright…
An international study led by researchers from Lund University in Sweden has found that a collision in the asteroid belt 470 million years ago created…
From the Great Pacific garbage patch to inland rivers, plastics are among the most widespread contaminants on Earth. Microplastics—particles of plastic smaller than five millimeters—are…
Over millions of years, Earth’s summits and valleys have moved and shifted, resulting in the dramatic landscapes of peaks and shadows we know today. Mountains…
Researchers suspect greater dynamics than previously assumed between the Earth’s surface and its mantle. What is the chemical composition of the Earth’s interior? Because it…
Volcanic eruptions and their ash clouds pose a significant hazard to population centers and air travel, especially those that show few to no signs of…
When the asteroid that wiped out the dinosaurs slammed into the planet, the impact set wildfires, triggered tsunamis, and blasted so much sulfur into the…
When significant oxygen entered the atmosphere, ancient life multiplied. But after a few hundred million years, Earth’s oxygen plummeted, resulting in a die-off likely greater…
Academics used to tease paleontologists, saying that while dinosaurs appeal to children, they won’t answer the important evolutionary questions. Yale’s John Ostrom (1928-2005) proved them…
Yale professor of geology and geophysics Jun Korenaga will take part in a new, NASA-supported project that will examine the specific conditions that led to…
An international team of researchers, including a NASA glaciologist, has discovered a large meteorite impact crater hiding beneath more than a half-mile of ice in…
When a coastal tide rolls out, it can reveal beautiful ripples in the temporarily exposed sand. These same undulating patterns can also be seen in…
