wn University professor Peter Schultz’s study of the Peruvian meteorite has yielded some interesting conclusions that could upend the conventional wisdom about the size and type of meteorites that can strike Earth.

One of the experiments housed on the European Columbus laboratory’s external platform is an automated eye in the sky known as the Earth Viewing Camera (EVC). Now, after several weeks of troubleshooting by the EVC team in the Netherlands, the first pictures from the orbiting camera have arrived safely back on Earth.

Geologists at the University of Illinois have confirmed the discovery of Earth’s inner, innermost core, and have created a three-dimensional model that describes the seismic anisotropy and texturing of iron crystals within the inner core.

The amount of information being generated about our planet is increasing at an exponential rate, but it must be easily accessible in order to apply it to the global needs relating to the state of the Earth.

Earth scientists are in the business of backing into history -- extrapolating what happened millions of years ago based on what they can observe now. Using this method, a team of Cornell researchers has created a mathematical computer model of the formation of granulite, a fine-grained metamorphic rock, in the Earth's crust.

An important discovery has been made with respect to the mystery of “handedness” in biomolecules. Researchers led by Sandra Pizzarello, a research professor at Arizona State University, found that some of the possible abiotic precursors to the origin of life on Earth have been shown to carry “handedness” in a larger number than previously thought.

Swedish researchers present in today’s Web edition of the journal Science evidence that their theory about the core of the earth is correct. Among other applications, the findings may be of significance for our understanding of the cooling down of the earth, and of the stability of the earth’s magnetic field.

The motion, formation, and recycling of Earth’s crust—commonly known as plate tectonics—have long been thought to be continuous processes. But new research by geophysicists suggests that plate tectonic motions have occasionally stopped in Earth’s geologic history, and may do so again.

Plate tectonics, the geologic process responsible for creating the Earth’s continents, mountain ranges, and ocean basins, may be an on-again, off-again affair.

It is widely known that the geomagnetic field shields our planet against highly energetic cosmic particles. The importance of the magnetic field for answering geological, tectonic or even archaeological questions is less known.

With powerful instruments scouring the heavens, astronomers have found more than 240 planets in the past two decades, none likely to support Earth-like life.

Using the Sun Earth Connection Coronal and Heliospheric Investigation (SECCHI) instruments on board NASA’s Solar Terrestrial Relations Observatory (STEREO) spacecraft, a consortium of scientists has seen, for the first time, large waves of solar material sweeping past Earth.
