Well, the verdict is in. The Moon is not made of green cheese after all. A thorough investigation published in May 2023 found that the inner core of the Moon is, in fact, a solid ball with a density ...

Earth’s core has two layers: a solid inner core made of iron and nickel and a liquid outer core of molten metal. The solid core is about 70% the size of the moon.

Although more than 99.95% of Earth's gold is locked in the molten core, tiny amounts may be coming up to the surface in magma, a study found. A lava fountain at Kilauea in Hawaii is seen in early May.

An analysis of Hawaii’s volcanic rocks revealed Earth’s core is leaking gold and other precious metals, a study found. The elements emerge when ocean islands form.

Earth’s core has two layers. A hot, solid metal sphere of iron and nickel is roughly 70% the size of the moon, with a radius of about 759 miles (1,221 kilometers). A liquid metal outer core is ...

While it's unlikely the deep-buried treasure chest will ever be cracked open, scientists call the discovery significant.

The record-breaking mission offers an unprecedented opportunity to study the geology of our planet’s largest layer.

As per their calculations, the Moon’s outer core has a radius of about 362 kilometers (225 miles). The solid inner core has a radius of approximately 258 kilometers (160 miles), which makes up ...

The Earth's inner core, long considered a solid and stable sphere, may be quite different. A recent study suggests that its surface is undergoing structural transformations, challenging our ...

A recent study revealed that Earth’s inner core is slowing down, prompting scientists to investigate further. Their research led to an unexpected discovery: that inner core is not entirely solid.

With the help of generative Al, we'll try to deliver answers based on our published reporting. Earth’s inner core — like a planet inside another planet — appears to move to its own beat.

It is basically a donut, or a large belt, wrapped around the outer core of the planet. The Earth’s core is 6,970 kilometers (4,330 miles) across and it is divided into an inner solid core and a ...
