In the study of lunar eclipses, NASA’s research into the varying shades and hues of a total lunar eclipse provides fascinating insights into the impact of this astronomical event on Earth’s atmosphere ...

WASHINGTON, D.C. — Earth’s inner core, a solid metal ball gyrating within the molten outer core, may be both slowing down and changing shape. Recent analyses of earthquake waves have suggested that ...

Material deep inside Earth — thousands of kilometres down, near the planet’s core — has undergone a mysterious shift. Is Earth’s core leaking? Volcanic rocks provide strongest evidence yet Although ...

Deep beneath our feet, something extraordinary is happening. Scientists have discovered that changes in Earth's core are directly influencing our planet's magnetic field in ways we're only beginning ...

We tend to think earthquakes are predominantly driven by deep-Earth forces. But in Kenya’s Lake Turkana Rift, researchers recently found that as surface water levels dropped roughly 100 to 150 meters ...

Climate change is lengthening our days because rising sea levels slow Earth's rotation. Researchers from the University of Vienna and ETH Zurich now show that the current increase in day length—1.33 ...

The sun is midway through its life of fusion. It's about 5 billion years old, and though its life is far from over, it will undergo some pronounced changes as it ages. Over the next billion years, the ...
