How do radar satellites work?

Radar allows us to see through what would otherwise be invisible. By sending out radio waves that bounce off objects and return as echoes, radar creates a detailed picture of our surrounding world.

This technology is everywhere: from guiding air traffic and enabling self-driving cars to tracking the movements of athletes. But its reach doesn’t stop there—radar is also transforming how we observe our Earth from space.

Satellites like the Copernicus Sentinel-1 mission use radar to see through clouds, darkness and any weather conditions. This capability is invaluable for detecting subtle changes on Earth’s surface—changes that are often hidden from the human eye. Discover how radar technology is helping us unlock these hidden insights about our planet.

How marine heatwaves impact phytoplankton and ocean health

Marine heatwaves – periods of prolonged, unusually warm seawater – are increasingly threatening marine ecosystems around the world. A recent study, led by the Institute of Marine Sciences of the National Research Council of Italy (CNR-ISMAR) as part of ESA’s CAREHeat project, specifically examined these effects in the North-Western Mediterranean Sea.

By combining satellite data from ESA’s Climate Change Initiative (ESA CCI), in situ robotic platforms called BioGeoChemical-Argo floats and Copernicus Marine’s biogeochemical models, the research highlights how these heatwaves significantly disrupt the spring phytoplankton bloom – a vital process for marine life.

Sound of Earth’s magnetic flip 41 000 years ago

Approximately 41 000 years ago, Earth’s magnetic field briefly reversed during what is known as the Laschamp event. During this time, Earth’s magnetic field weakened significantly—dropping to a minimum of 5% of its current strength—which allowed more cosmic rays to reach Earth’s atmosphere.

Scientists at the Technical University of Denmark and the German Research Centre for Geosciences used data from ESA’s Swarm mission, along with other sources, to create a sounded visualisation of the Laschamp event. They mapped the movement of Earth’s magnetic field lines during the event and created a stereo sound version which is what you can hear in the video.

The soundscape was made using recordings of natural noises like wood creaking and rocks falling, blending them into familiar and strange, almost alien-like, sounds. The process of transforming the sounds with data is similar to composing music from a score.

Data from ESA’s Swarm constellation are being used to better understand how Earth’s magnetic field is generated. The satellites measure magnetic signals not only from the core, but also from the mantle, crust, oceans and up to the ionosphere and magnetosphere. These data are crucial for studying phenomena such as geomagnetic reversals and Earth’s internal dynamics.

The sound of Earth’s magnetic field, the first version of the magnetic field sonification produced with Swarm data, was originally played through a 32-speaker system set up in a public square in Copenhagen, with each speaker representing changes in the magnetic field at different places around the world over the past 100 000 years.
