Earth’s inner core is a hot, solid ball—about 20% of Earth’s radius ... and currents induce a magnetic field, convection and rotation produce our planet’s magnetic fields. But these models typically ...

Thanks to a new study proves that Earth's inner core since 2010 has been rotating more slowly than usual. This intriguing ...

Currently, the rotation between the inner and outer cores is becoming less distinct. When researchers say “reverse,” they mean the inner core is rotating slightly slower than the outer core, Brown ...

The Earth’s magnetic field is why we are here today. It protects life from harmful radiation from the Sun and many other cosmic events. It is generated in the liquid outer core of our planet, but ...

We have been adding “leap seconds” to time kept by our atomic clocks, but soon we may have to subtract one. Are the tiny adjustments worth the bother?

The closest star to Earth is also the best studied, but only recently have we truly begun to uncover its secrets.

A close flyby of an asteroid as large as Apophis happens only once every 5,000 to 10,000 years. Scientists plan to learn all they can.

A new European Space Agency mission is set to study asteroid Apophis to learn more about how we can handle asteroid threats ...

Apophis is 340 metres wide, about the same as the height of the Empire State Building. If it were to hit Earth, it would ...

There's evidence out there for the supernova model of black hole formation. This is when a dying star erupts in a colossal ...

In contrast, the long-term fluctuations in inner core rotation remain proportional to the fluid core angular velocity, with no apparent dependency on the Ekman number. If the same torque balance ...

The European Space Agency has given the go-ahead for initial work on a mission to visit an asteroid called (99942) Apophis.
