Earth’s Core Unveiled: Seismic Clues Point to an Onion-like Inner Iron Layer
New Evidence Suggests an Onion-like Core Structure For decades, scientists have probed Earth’s interior with seismic waves that travel through the planet during earthquakes. A new wave of research synthesizes these signals to paint a surprising picture of the Earth’s core: the inner iron center may be layered in a way that resembles an onion…

Earth’s Core Revealed by Seismic Waves: Layered Truth
Introduction: A Layered View of Earth’s Core Recent seismic analyses have transformed our understanding of Earth’s iron heart. By tracking how seismic waves travel through and around the inner core, scientists are uncovering a layered structure that behaves like an onion—and sometimes in surprising, counterintuitive ways. The new findings suggest not only a multilevel inner…

Earth’s Core Revealed as Onion-Like with Layered Iron Interior
New clues from seismic waves illuminate Earth’s iron heart For decades, scientists have peered into the depths of our planet using the vibrations that ripple through Earth after earthquakes. A new study of seismic waves passing through the inner core has unveiled surprising details about the iron center, suggesting it is not a uniform sphere…

Uncovering the mystery behind colorful aurora skies
What causes the colorful aurora skies? The aurora borealis in the northern hemisphere and the aurora australis in the southern hemisphere are nature’s most spectacular light show. At the heart of the phenomenon is the Sun’s wind—a stream of charged particles that travels through space and toward Earth. When these particles collide with atoms and…

From Mantle Flow to River Flow: How Earth’s Interior Shapes Surface Features
Introduction: Reading the Earth’s Hidden Currents The Earth’s surface bears the fingerprints of processes operating far below our feet. A new global synthesis, inspired by recent work featured in Geophysical Research Letters, connects the deep dynamics of mantle flow with the visible architecture of faults, fractures, and river systems. By tracing how the slow, buoyant…

Near-Surface Cooling Stalls Giant Dyke Swarms in Crust
Understanding Giant Dyke Swarms Giant dyke swarms are expansive networks of long, sheet-like cracks in Earth’s crust that channel magma laterally. These structures play a crucial role in how molten rock moves from deep reservoirs toward shallower levels, influencing volcanic behavior, crust formation, and mineral resource distribution. Recent research emphasizes how cooling near the surface…
