A role for meteoritic iron in the emergence of life on Earth

Researchers from the Max Planck Institute for Astronomy and Ludwig Maximilians University Munich have proposed a new scenario for the emergence of the first building blocks for life on Earth, roughly 4 billion years ago.

Mars rovers safe from lightning strikes, research finds

If experiments done in small bottles in a University of Oregon lab are accurate, the friction of colliding Martian dust particles are unlikely to generate big electrical storms or threaten the newly arrived exploration vehicles ...

Where does the Earth's heat come from?

Earth generates heat. The deeper you go, the higher the temperature. At 25km down, temperatures rise as high as 750°C; at the core, it is said to be 4,000°C. Humans have been making use of hot springs as far back as antiquity, ...

Synchronization of ice cores using volcanic ash layers

Thin, brownish layers of a thickness of about a millimeter or two are sometimes observed in the whitish/transparent ice cores. These brown layers consist of material originating from volcanic eruptions.

Chaos theory provides a way for determining how pollutants travel

Floating air particles following disasters and other largescale geological events can have a lasting impact on life on Earth. Volcanic ash can be projected up to the stratosphere and halt air traffic by lingering in the atmosphere ...

Volcanic ash particles under the microscope

Volcanic ash is hazardous to many aspects of our lives. When airborne, it can damage aircraft: its particles abrade aeroplane surfaces and can even cause failure to critical instruments. Once the ash falls, it can harm our ...
