The air we breathe

Air pollution is a global environmental health problem, especially for those living in urban areas. Not only does it negatively impact our ecosystems, it considerably affects our health. According to the World Health Organization (WHO), around 8 million premature deaths per year are linked to air pollution, more than double of previous estimates. To source

From canals to craters

Mars was once believed to be criss-crossed by a system of irrigation canals – dark troughs that sliced across the planet’s surface, excavated by an intelligent society of thirsty martians. The astronomer who promoted this idea lends his name to the crater shown in this image from ESA’s Mars Express: Lowell crater. To source

3D Earth in the making

A thorough understanding of the ‘solid Earth’ system is essential for deciphering the links between processes occurring deep inside Earth and those occurring nearer the surface that lead to seismic activity such as earthquakes and volcanic eruptions, the rise of mountains and the location of underground natural resources. Thanks to gravity and magnetic data from […]

Water cycle wrapped

As our climate changes, the availability of freshwater is a growing issue for many people around the world. Understanding the water cycle and how the climate and human usage is causing shifts in natural cycling processes is vital to safeguarding supplies. While numerous satellites measure individual components of the water cycle, it has never been […]

Tug-of-war drives magnetic north sprint

As far as we know, Earth’s magnetic north has always wandered, but it has recently gained new momentum and is making a dash towards Siberia at a pace not seen before. While this has some practical implications, scientists believe that this sprint is being caused by tussling magnetic blobs deep below our feet. To source
