For the first time in its history, humanity is assembling a coordinated system to find, track, and deflect asteroids that ...

Scientists suggest that huge reserves of hydrogen inside the Earth may have been key in the formation of water.

One of the strangest mysteries about our Earth is the presence of two dense, giant blobs inexplicably clustered above the planet's core. "These are not random oddities," says geodynamicist Yoshinori ...

In A Nutshell Two massive hot regions deep beneath Africa and the Pacific Ocean have been influencing Earth’s protective ...

Earth's core contains nine to 45 times more hydrogen than the planet's oceans do, according to a new study that could settle a debate about when and how hydrogen was delivered to Earth.

Hidden mega-structures deep inside Earth may have been quietly steering our planet’s magnetic field—and rewriting what we thought we knew about Earth’s past.

Scientists in a rare discovery have found “smiling electrons” inside Earth’s protective magnetic field. According to a new ...

Cosmic rays inside a dense molecular cloud were measured for the first time, helping scientists better understand how stars begin forming.

Scientists now understand why seismic waves speed up near Earth's core. Extreme pressure and temperature cause solid mantle rock to flow slowly, aligning mineral crystals. This anisotropic structure ...

A newly studied solar system breaks the usual planet pattern, raising fresh questions about how rocky and gas planets form.

For decades, scientists have been baffled by two enormous, enigmatic structures buried deep inside Earth with features so vast and unusual that they defy conventional models of planetary evolution.

Simulations suggest that two enormous masses of hot rock have been involved in generating Earth’s magnetic field and giving it an irregular shape ...
