  • Earth's Oldest Rocks
    Scientists have discovered rocks that are 4.28 billion years old, making them 250 million years more ancient than any previously discovered rocks. Our planet formed about 4.6 billion years ago, so these rocks could provide a unique window on the young Earth.

  • Lukewarm Supervolcano
    Yellowstone is known for its hot springs and geysers, and the unique forms of life that inhabit them. Scientists are now learning more about the mysterious 'supervolcano' that powers these environments, and whether or not the giant could erupt again.

  • Complex Volcanoes
    For the first time, scientists have mapped an elaborate maze of magma chambers beneath the volcanoes of Iceland. The unique view into a complex subterranean world could provide important information about earthquakes and volcanic eruptions.

  • Revising Earth's History
    Geologists have found that major basins in India are 500 million years older than previously thought. The study may lend weight to idea that complex life originated earlier in Earth's history.

  • Lava Holds Clues to Planet Formation
    An analysis of lava samples from Hawaii has given scientists a new tool for reconstructing planetary origins. The study will help us understand how planets form, and may help in the search for terrestrial planets beyond our solar system.

  • Early Acid Rain
    A new study of ancient minerals shows that the earliest continents on Earth may have been scoured and destroyed by the planet's harsh climate. The study has also demonstrated that the Earth may have been habitable as early as 4.3 billion years ago.

  • Deep Hydrogen
    Molecular hydrogen provides energy for many bacteria, in hot springs at Yellowstone and in rocks several kilometers beneath the surface. How did molecular hydrogen get inside these deep rocks, and what does this tell us about the origin of life on Earth?
