Lab experiments simulating inner-core conditions suggest iron–carbon alloy enters a superionic state, with mobile light atoms softening the solid and slowing seismic waves, potentially explaining long-standing seismic anomalies and offering new insights into Earth's magnetic field generation.
A new study suggests Earth's inner core is layered like an onion, with variations in seismic wave speeds explained by the distribution of silicon and carbon in iron alloys, revealing a complex, stratified structure deep beneath the surface.
Scientists from Oxford, Leeds, and UCL discovered that carbon played a crucial role in Earth's inner core formation, reducing supercooling requirements and potentially more abundant than previously thought, which impacts our understanding of Earth's magnetic field and interior dynamics.
A new study suggests that the presence of about 4% carbon in Earth's core allowed the iron to solidify under high pressure and temperature conditions, explaining how the planet's inner core froze and providing insights into Earth's geological history.
Scientists have discovered that Mars has a solid inner core enclosed by a liquid outer core, similar to Earth's internal structure, which provides new insights into the planet's geological history and past magnetic field, helping to explain its evolution and loss of atmosphere.
Scientists using NASA's InSight mission have discovered that Mars has a solid inner core surrounded by a liquid outer core, similar to Earth's structure, which has important implications for understanding the planet's evolution and past magnetic field.
NASA's InSight mission has discovered that Mars has a solid inner core about 600 km across, contrary to previous beliefs that it was entirely soft, providing new insights into the planet's internal structure and evolution.
Scientists have confirmed that the Moon's inner core is a solid sphere made of iron-like material, reshaping our understanding of its internal structure and magnetic history, using a combination of space mission data and lunar laser-ranging experiments.
Scientists confirmed that the Moon has a solid inner core similar in density to iron, with an outer fluid layer, supporting the idea of an Earth-like lunar core and providing insights into the Moon's magnetic history and evolution.
Scientists confirmed that the Moon has a solid inner core similar in density to iron, with a fluid outer layer, supporting models of an Earth-like lunar interior and providing insights into the Moon's magnetic history and evolution.
Climate change is causing Earth's ice caps to melt, leading to a redistribution of mass towards the equator and slowing Earth's rotation, thus lengthening days. This shift, combined with natural tidal braking from the moon, could impact global time-keeping, digital infrastructure, and space travel. Additionally, Earth's inner core has been slowing down for 14 years, further contributing to changes in Earth's rotation.
Researchers have discovered a solid metal ball in the heart of Earth's innermost core, estimated to be roughly the size of Pluto and at least 400 miles thick. This finding challenges the conventional understanding of Earth's layers and suggests the existence of a fifth layer. Seismologists studied shockwaves from earthquakes to make this discovery and believe that the metal ball may have been formed as a result of a major global tectonic event in the past.
Scientists have discovered a massive solid metal ball, known as the "innermost inner core," within Earth's core, which is approximately 800 miles in diameter and makes up nearly one percent of the Earth’s volume. This discovery, made by seismologists at the Australian National University, has provided new insights into the Earth's core and its potential impact on the evolution of life on the planet's surface. The solid metal core is believed to have formed after a significant tectonic event and could hold clues to understanding the evolution of life on Earth.
Earth's inner core has been found to wobble with a periodicity of 8.5 years, revealing a tilt of 0.17 degrees between the inner core and the mantle. This suggests that the inner core is denser in the northwestern hemisphere. The discovery provides new insights into the inner workings of our planet and could help interpret surface manifestations of behavior at the core. The inner core's rotation and density variations may play a role in generating Earth's magnetic field. Further research is needed to fully understand the complexities of Earth's core.
Scientists have made a surprising discovery about Earth's core, finding that the "innermost inner core" is a giant metal ball about 400 miles wide, slightly different from the rest of the inner core. This metal core may have different properties and could be a "fossilized record" of a significant tectonic event. The findings could provide insights into the evolution of life on Earth.
