The planet WASP-121b is extreme. It's a gas giant almost twice as big as Jupiter orbiting extremely close to its star–50 ...

Mars' atmosphere moves differently from Earth's due to gravity waves. These waves affect air circulation at high altitudes.

For a long time, scientists thought the Earth's inner core was a solid ball of metal, sort of like a planet within a planet ...

Seismic waves suggest the planet's solid inner core is being pulled out of shape – and it has undergone these changes over just a few decades ...

IT’S been nearly 40 years since the first planet outside of our Solar System was discovered. Since then, more than 5,800 weird and wonderful worlds across 4,300 planetary systems have been ...

Surprising differences in the two so-called Large Low-Velocity Provinces may risk instability in Earth's protective magnetic ...

A new study by researchers including those at the University of Tokyo revealed that atmospheric gravity waves play a crucial ...

This makes a significant difference in the planet’s moment of inertia, which in turn slightly slows the rotation of Earth. The dam has prolonged the length of a day by 0.06 microseconds, according to ...

Our readers offer their opinions on what would happen if Earth’s rotation slowed – and if it sped up. Life wouldn’t be easy for our planet’s inhabitants, let’s put it like that ...

Previous research has found that the rotation of the inner core is slowing down relative to the rotation of the external ...

Saturn's iconic ring system will disappear, albeit temporarily, on March 23—a preview of its fate in 100 million years.
