While Earth seems safe, the Moon still faces a minor risk. There’s a small chance– just a few percent– that 2024 YR4 could collide with the lunar surface.

Recent studies reveal that climate change is subtly altering Earth's shape and increasing the length of days. Melting polar ice sheets are redistributing mass towards the equator, causing the ...

So, Earth's orbit only has a relatively tiny deviation from perfect circularity. But why is it so often shown as practically an egg shape? And how can we visualize the real situation? Consider the ...

They created life-sized, 3D-printed insect models to simulate the look of real wasps and their harmless mimics, such as hoverflies. This method allowed scientists to precisely manipulate traits like ...

A wealth of new information about Earth’s inner core has surfaced in recent months. Scientists now have evidence that the planet’s innermost layer is changing shape. Sign up for CNN’s Wonder Theory ...

Researchers at TU Wien have developed a new way to grow cartilage from stem cells and guide it into basically any shape required. The breakthrough could lead to better ways to patch up injuries.

A wealth of new information about Earth’s inner core has surfaced in recent months. Scientists now have evidence that the planet’s innermost layer is changing shape.

But Array Labs, a two-year-old startup based in Silicon Valley, is also taking advantage of other technological developments in its quest to build a 3D map of Earth.

Earth’s inner core is changing shape, scientists have found. The discovery resolves a long-simmering controversy about what’s happening at the heart of the planet — which was long thought to ...

The waveforms, or shapes, of some of the seismic signals changed between 2004 and 2008. Those shifts occurred because the waves briefly penetrated Earth’s inner core — which was changing shape ...

Researchers studying decades of earthquake data say they have found the first evidence that, in addition to spinning backward, Earth’s inner core in changing shape.
