One of the most comprehensive pictures of our changing planet is now available to the public. Thanks to the close collaboration between Google Earth, ESA, the European Commission, NASA and the US Geological Survey, 24 million satellite photos from the past 37 years have been embedded into a new layer of Google Earth – creating a new, explorable view of time on our planet.

Italy’s Mount Etna, Europe’s most active volcano, has recently been on explosive form, with 17 eruptions in less than three months. Instruments onboard three different satellites orbiting Earth have acquired imagery of the eruptions – revealing the intensity of the lava-fountaining eruptive episodes, known as paroxysms.

Climate change is having an undeniable influence on coastal areas. A substantial proportion of the world’s sandy coastlines are already eroding owing to increased storm surges, flooding and sea level rise. With our coastal environments in constant change, Earth observation satellites are being used to better strengthen our knowledge of changing coastlines. View the full article

For well over a decade, ESA’s SMOS satellite has been delivering a wealth of data to map moisture in soil and salt in the surface waters of the oceans for a better understanding of the processes driving the water cycle. While addressing key scientific questions, this exceptional Earth Explorer has repeatedly surpassed expectations by returning a wide range of unexpected results, often leading to practical applications that improve everyday life. Adding to SMOS’ list of talents, new findings show that what was considered noise in the mission’s data can actually be used to monitor solar activity and space weather, which can damage communication and navigation systems.

Fluctuations in the carbon-rich biomass held within the world’s forests can contribute to, or slow, climate change. A series of new maps of above ground biomass, generated using space observations, is set to help our understanding of global carbon cycling and support forest management, emissions reduction and sustainable development policy goals.

In early 2020, data from satellites were used to show a decline in air pollution coinciding with nationwide lockdowns put in place to stop the spread of COVID-19. One year later, as lockdown restrictions loosen in some countries and regular activity resumes, nitrogen dioxide levels are bouncing back to pre-COVID levels. View the full article

Despite ESA’s GOCE mission ending over seven years ago, scientists continue to use this remarkable satellite’s gravity data to delve deep and unearth secrets about our planet. Recent research shows how scientists have combined GOCE data with measurements taken at the surface to generate a new model of Earth’s crust and upper mantle. This is the first time such a model has been created this way – and it is shedding new light on processes of plate tectonics, which, in turn, are related to phenomena such as earthquakes and volcanic eruptions.
