Earth is made up of several layers: the lithosphere, asthenosphere, lower mantle (also known as mesospheric mantle), outer core and inner core.

NASA discovers K2-360 b, a super-dense 'super-Earth' 750 light-years away, with 8 Earth masses packed into 1.6x Earth’s size, orbiting its star in just 21 hours.

The solid layer of Earth’s mantle lies between the crust and the core and is about 2,900 kilometers (1,802 miles) thick, making up 84% of Earth's volume and 67% of its mass.

The junction between layers of atmosphere is usually not a discreet line, but rather a transition zone where one blends into another. The change may happen over miles.

A discovery about Earth's core shows a "doughnut" shaped layer, in which earthquake waves travel slower than the rest of the core. A study published in Science Advances points to silicon and ...

The ozone layer is a part of Earth’s atmosphere that captures some of the Sun’s ultraviolet (UV) light emissions. When the ozone layer is compromised, its ability to absorb radiation weakens ...

But now, Professor Hrvoje TkalÄ ić, also from ANU, said new learnings about the earth’s inner core could reveal more about the planet’s past and evolution.

Every 8.5 years or so, the Earth emits a signal—the result of a “wobble” occurring in the inner core. To explain this phenomenon, scientists from Wuhan University analyzed polar movement and ...

Scientists have known about Earth’s ozone layer for over a century, but it wasn’t until the 1970s that they grew concerned about its integrity. Early in the decade, ...
