Tools to better predict floods and droughts

The fact that water accounts for about 71% of the Earth's surface is common knowledge. What is less known, however, is that this water mass is constantly redistributing and that such changes can be responsible for floods ...

Leaky atmosphere linked to lightweight planet

The Red Planet's low gravity and lack of magnetic field makes its outermost atmosphere an easy target to be swept away by the solar wind, but new evidence from ESA's Mars Express spacecraft shows that the Sun's radiation ...

What would happen if the Earth were actually flat?

Welcome to the new year, 2018. The Earth has yet again made a revolution about the sun. But not so fast. If you subscribe to the idea of a flat Earth, then you'd believe that no such thing happened, because the sun rotates ...

New gravity map suggests Mars has a porous crust

NASA scientists have found evidence that Mars' crust is not as dense as previously thought, a clue that could help researchers better understand the Red Planet's interior structure and evolution.

How strong is the force of gravity on Earth?

Gravity is a pretty awesome fundamental force. If it wasn't for the Earth's comfortable 1 g, which causes objects to fall towards the Earth at a speed of 9.8 m/s², we'd all float off into space. And without it, all us terrestrial ...

What's inside Ceres? New findings from gravity data

In the tens of thousands of photos returned by NASA's Dawn spacecraft, the interior of Ceres isn't visible. But scientists have powerful data to study Ceres' inner structure: Dawn's own motion.

Caribbean Sea acts like a whistle and can be 'heard' from space

A study of the Caribbean Sea by University of Liverpool ocean scientists has revealed that, in the midst of all the noise of the ocean, this region behaves like a whistle, which blows so loudly that it can be 'heard' from ...

New gravity map gives best view yet inside Mars

A new map of Mars' gravity made with three NASA spacecraft is the most detailed to date, providing a revealing glimpse into the hidden interior of the Red Planet.
