Swaying mountains
Swaying mountains
The Matterhorn appears as an immovable, massive mountain that has towered over the landscape near Zermatt for thousands of years. A study now shows that this impression is wrong. An international research team has proven that the Matterhorn is instead constantly in motion, swaying gently back and forth about once every two seconds.

Analysis of Mars’s wind-induced vibrations sheds light on the planet’s subsurface properties
Seismic data collected in Elysium Planitia, the second largest volcanic region on Mars, suggest the presence of a shallow sedimentary layer sandwiched between lava flows beneath the planet's surface. These findings were gained in the framework of NASA's InSight mission (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport), in which several international research partners, including the University of Cologne, collaborate.

Bombardment of Planets in the Early Solar System
Bombardment of Planets in the Early Solar System
Studies of the asteroid Vesta provide new findings on the formation of Earth-like planets The largest asteroid in our Solar System - Vesta - was exposed to an extensive series of impacts by large rocky bodies much earlier than previously assumed. Researchers of an international collaboration, including earth scientists of Heidelberg University and Freie Universität Berlin, reached this conclusion based on analyses of Vesta meteorites, numerical simulations, and observations carried out with the space probe Dawn in 2011 and 2012.

Virtual experiments: Münster University geophysicists research the Earth’s origins on the computer
Although Dr. Christian Maas does his research only on the computer, it's sometimes as if he were standing in a laboratory. "I do experiments," he says. By means of his virtual experiments, geophysicist Maas is investigating a question that couldn't be answered in any lab in the world: the question of the how the Earth came into being.

The inner beauty of hailstones
The inner beauty of hailstones
The Tübingen region has recently seen hailstorms that brought back memories of the devastating storm of 2013. At that time, billions of dollars in damage were caused, and the damage from the most recent storms is still being assessed. Despite all the trouble hailstones cause, they also possess a previously unknown inner beauty.

Continuous activity of small earthquakes makes mountains grow
Continuous activity of small earthquakes makes mountains grow
From a human perspective, earthquakes are natural disasters - in the past hundred years, they have caused more than 200,000 deaths and enormous economic damage. Mega-earthquakes with a magnitude of nine or higher on the Richter scale are considered a particular threat. Yet the inconceivable energy released in these events doesn't seem to affect the uplift of mountains, according to a new study by geoscientists at the University of Tübingen.

Long-term Himalayan Glacier Study
Heidelberg University geographers combine historical images and maps with current data The glaciers of Nanga Parbat - one of the highest mountains in the world - have been shrinking slightly but continually since the 1930s. This loss in surface area is evidenced by a long-term study conducted by researchers from the South Asia Institute of Heidelberg University.

Extreme CO2 greenhouse effect heated up the young Earth
Although sun radiation was relatively low, the temperature on the young Earth was warm. An international team of geoscientists has found important clues that high levels of carbon dioxide in the atmosphere were responsible for these high temperatures. It only got cooler with the beginning of plate tectonics, as the CO2 was gradually captured and stored on the emerging continents.

Warm seas when the Earth was still young?
Researchers from the Universities of Göttingen, Cologne and Århus calculate the water temperatures of the first oceans For decades, there has been controversy about the water temperatures of the first oceans on Earth. At that time, radiation from the Sun was much weaker and the oceans could have been very cold, perhaps even frozen.

Solar Wind From the Centre of the Earth
Model for the Earth's core: Heidelberg researchers verify presence of solar noble gases in metal of an iron meteorite High-precision noble gas analyses indicate that solar wind particles from our primordial Sun were encased in the Earth's core over 4.5 billion years ago. Researchers from the Institute of Earth Sciences at Heidelberg University have concluded that the particles made their way into the overlying rock mantle over millions of years.

Is Climate Sensitivity Higher Than Believed?
Meta-study on noble gas concentrations in ground water reconstructs climate in the last Ice Age The last Ice Age about 20,000 years ago may have been colder than previous reconstructions of the period's global temperature have led us to believe. An international meta-study to which Werner Aeschbach of the Institute of Environmental Physics at Heidelberg University contributed suggests this may have been the case.

Seasonal Water Resource on the Upper Indus
Seasonal Water Resource on the Upper Indus
Heidelberg geographers draw up full inventory of barely researched aufeis (icing) fields Seasonally occurring fields of aufeis (icing) constitute an important resource for the water supply of the local population in the Upper Indus Basin. However, little research has been done on them so far. Geographers at the South Asia Institute of Heidelberg University have now examined the spreading of aufeis and, for the first time, created a full inventory of these aufeis fields.
