The rapid evolution of Egypt’s Nile Delta over the last four years, as viewed from ESA’s Proba-V microsatellite. Think of it as a small token of our love for planet Earth: just a cubic metre in size, Proba-V maps land cover and vegetation growth across the entire world every two days.www.esa.int
When astronauts take photographs of our planet while orbiting 400 km above our heads, they are doing much more than just taking pretty pictures. They are looking after the health of our planet and, ultimately, us too.www.esa.int
Earth observation satellite data are crucial for generating accurate weather predictions. They provide a global picture of the current state of the atmosphere, which is used as the starting point for creating a forecast. But our knowledge of that current state is limited, partly because …www.esa.int

Since it was first measured in 1831, we have known that the magnetic north is constantly on the move. However, its tendency to slowly roam has stepped up a pace recently – so much so that the World Magnetic Model has had to be updated urgently with the pole’s new location, vital for navi…www.esa.int
