In 2025, scientific discoveries revealed Earth's ancient crust in Quebec, explained phenomena like will-o'-the-wisps through microlightning, tracked the movement of magnetic north, discovered a deep-sea methane-based ecosystem, and observed changes in Earth's core, deepening our understanding of the planet's history and inner workings.
New research pushes back the timeline of LUCA, the last universal common ancestor, to about 4.2 billion years ago during Earth's Hadean Eon, suggesting life was active and evolving in extreme conditions much earlier than previously thought, with signs of primitive immune systems and environmental interaction.
Recent research indicates Earth's continents formed much earlier than previously believed, around 4.3 billion years ago, driven by active tectonic processes and mantle plumes during the Hadean, challenging the idea of a stagnant early Earth and providing new insights into crust formation and mantle recycling.
A new study suggests that subduction and continental crust formation on Earth began hundreds of millions of years earlier than previously believed, during the Hadean Eon, indicating a more active early Earth than traditionally thought.
Scientists have confirmed that the oldest rocks on Earth, located in northern Québec's Nuvvuagittuq Greenstone Belt, are over 4.16 billion years old, providing rare insights into Earth's earliest history and the conditions during the Hadean Eon.
Scientists have confirmed the discovery of the oldest rocks on Earth in northern Quebec, dating back approximately 4.16 billion years, providing valuable insights into Earth's early crust and the planet's formation during the Hadean eon.
A new dating analysis suggests that parts of the Nuvvuagittuq Greenstone Belt in Canada are as old as 4.16 billion years, making it one of the oldest known surface rocks on Earth and providing valuable insights into Earth's early history.
Scientists have identified what may be Earth's oldest rocks, dating back 4.16 billion years in the Nuvvuagittuq Greenstone Belt, providing insights into the planet's early history and the Hadean Eon, though some debate remains about the dating accuracy.
A study of ancient zircon crystals from the Australian outback reveals that Earth had dry land and fresh water 4 billion years ago, challenging the belief that the planet was entirely ocean-covered at that time. This discovery suggests that the conditions necessary for life existed much earlier than previously thought, providing new insights into Earth's early history and the origins of life.
