A multidisciplinary group of Cornell researchers has modeled and synthesized lava in the laboratory as the kinds of rock that may form on far-away exoplanets. They developed 16 types of surface compositions as a starter catalog for finding volcanic worlds that feature fiery landscapes and oceans of magma.

About two billion years ago, an impactor hurtled toward Earth, crashing into the planet in an area near present-day Johannesburg, South Africa. The impactor—most likely an asteroid—formed what is today the biggest crater on our planet.

Cornell University archaeologist Sturt Manning hopes to settle one of modern archaeology’s longstanding disputes: the date of a volcanic eruption on the Greek island of Santorini, traditionally known as Thera.
Pittsburgh’s steel industry may be largely in the past, but its legacy lives on in city soils. New research led by Pitt geologists shows how historical coking and smelting dropped toxic metals in Pittsburgh’s soil, particularly in the eastern half of the city. With samples from 56 parks, cemeteries and other sites around the city collected by Carnegie Mellon University students and Jonathan Burgess from the Allegheny County Conservation District, the team was able to pinpoint some of those polluting factors. They recently published their results in the journal Environmental Research Communications.
By: Kathleen Haughney | Published: September 19, 2022 | 4:01 pm | SHARE: Mexico is dealing with the fallout of a powerful 7.6 magnitude earthquake that occurred near the Pacific coast on the anniversary of two previous tremors. Earthquakes occurred on Sept. 19 in both 1985 and 2017 in Mexico, killing thousands of people.Florida State University Professor of Geology James Tull is available to speak with reporters about the effects of the earthquake and the geology behind this catastrophic event.

Scientists have shed new light on the timing and likely cause of major volcanic events that occurred millions of years ago and caused such climatic and biological upheaval that they drove some of the most devastating extinction events in Earth’s history.
Curtin researchers and international collaborators using advanced satellite imagery have discovered an ancient reef-like landform ‘hidden’ in plain view on the Nullarbor Plain, which has been preserved for millions of years since it first formed when the Plain was underwater.
Let’s pretend it’s the Late Cretaceous, roughly 66 to 100 million years ago.
A little Martian dust appears to go a long way. A small amount of simulated crushed Martian rock mixed with a titanium alloy made a stronger, high-performance material in a 3D-printing process that could one day be used on Mars to make tools or rocket parts.
Tens of tons of extraterrestrial solid material collide with Earth daily. Most of this material is small enough that it burns up in the atmosphere, but some fragments are large enough to cause quite a predicament.

A few years ago, Rensselaer Polytechnic Institute’s Sasha Wagner, assistant professor of earth and environmental sciences, proved false what scientists had thought for years. Soot-like molecules that formed an ancient carbon pool deep in the Pacific Ocean did not, in fact, originate from wildfires on land.“We discovered that there was an isotopic mismatch,” Wagner said.

Imaging techniques provide essential information in astronomical and space physics studies. The Soft X-ray imager (SXI) will obtain images of the Earth’s magnetosphere from solar wind charge exchange emission in a global view.
University of Cincinnati geologists reconstructed a massive landslide in Nevada that wiped out an area the size of a small city more than 5 million years ago.
Using machine learning to sift through a decade’s worth of seismic data, researchers have identified hundreds of thousands of microearthquakes along some previously unknown fault structures in Oklahoma and Kansas.
Closure of the Neo-Tethys Ocean and the subsequent formation of the Tibetan Plateau is one of the most significant tectonic events on Earth.
The accepted view of Mars is red rocks and craters as far as the eye can see.
In its first year exploring Jezero Crater on Mars, the Perseverance rover collected rock samples that scientists anticipate will provide a long-awaited timeline for the planet’s geologic and water history.
Scientists on NASA’s Perseverance mission made a surprising discovery about the composition of rock in Jezero Crater, one that will help them get a better idea of when water existed on Mars, and ultimately, help them understand if the red planet was ever habitable to microbial life.
A new study of zircon crystals from two of Earth’s oldest continents indicates that the formation of Earth’s continental crust goes through cycles, with periods of increased crust production roughly every 200 million years, corresponding to the solar system’s transit through the four primary spiral arms of the Milky Way galaxy.
New Curtin research has found evidence that Earth’s early continents resulted from being hit by comets as our Solar System passed into and out of the spiral arms of the Milky Way Galaxy, turning traditional thinking about our planet’s formation on its head.
A new research center is exploring the use of fiber-optic sensing for seismology, glaciology, and even urban monitoring. Funded in part with a $473,000 grant from the M.J. Murdock Charitable Trust, the new UW Photonic Sensing Facility will use photons traveling through a fiber-optic cable to detect ground motions as small as 1 nanometer.
The ‘Lithium-Ion Battery State’ may not have the same ring to it as ‘Battle-Born’ or ‘Silver State,’ but the reality is that Nevada could soon be a leader in the lithium battery supply chain – potentially giving the U.S. an edge in the arms race for the in-demand metal that’s the key to powering everything from your cell phone to electric vehicles.
The eruption of the Hunga Tonga-Hunga Ha’apai volcano in January created an initial wave 90 metres high – almost the height of the Statue of Liberty (93m)

More of the world’s coastal glaciers are melting faster than ever, but exactly what’s triggering the large-scale retreat has been difficult to pin down because of natural fluctuations in the glaciers’ surroundings. Now, researchers have developed a methodology that they think cracks the code to why coastal glaciers are retreating, and in turn, how much can be attributed to human-caused climate change.
