Chefs have long used a simple trick to differentiate between a raw and hard-boiled egg. By spinning an egg and watching how it behaves when the spin is disrupted, it’s easy to tell whether its ...

Scientists have made an astonishing discovery about Mercury, the smallest and innermost planet in our solar system: some of its core might be made of diamonds. This revelation comes from a recent ...

In brief: Mercury is the smallest planet in the solar system and has always been a mystery due to its dark surface and high core density. However, astronomers have long known that its surface contains ...

Researchers working with high-precision planetary radars, including the Goldstone Solar System Radar of NASA’s Jet Propulsion Laboratory, Pasadena, Calif., have discovered strong evidence that the ...

"We calculate that, given the new estimate of the pressure at the mantle-core boundary, and knowing that Mercury is a carbon-rich planet, the carbon-bearing mineral that would form at the interface ...

A recent theory has emerged suggesting that the answer to Mercury’s unusually large metallic core may lie in the early history of our solar system. This theory proposes that a soft collision between ...

The early years of our solar system were a period of unimaginable chaos and violence, a gravitational free-for-all where colliding planetary embryos competed for survival. In this tumultuous ...

WASHINGTON -- Researchers have cracked a mystery at the core of Mercury -- and say there's molten fluid inside the tiny planet. They did it by using the same trick as cooks who want to know if an egg ...
