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.

Summer solstice 2024

Summer officially begins in the Northern Hemisphere today 20 June, marking the longest day of the year. The summer solstice, which is when the Sun reaches the most northerly point in the sky, is set to occur tonight at 21:50 BST/22:50 CEST.

During the summer solstice, the Northern Hemisphere will experience the longest period of sunlight in a day or the longest day of the year. This is because of Earth’s position in orbit around the Sun and the way the North Pole is tilted towards the Sun during the solstice. 

The Sun’s rays hit the Northern Hemisphere at their most direct angle, resulting in the most extended period of daylight. Despite the long hours of daylight, it may not necessarily be the hottest day of the year.

With the climate crisis increasingly affecting our planet, EarthCARE is poised to provide data for climate research, to improve the accuracy of climate models and to support numerical weather prediction.

EarthCARE is the most complex of ESA’s trailblazing Earth Explorer research missions – missions that deliver critical information to understand how our world functions and the impact that human activity is having on natural processes.

Unravelling the mysteries of clouds

Clouds are one of the biggest mysteries in the climate system. They play a key role in the regulating the temperature of our atmosphere. But we don’t know how their behaviour will change over time as Earth’s atmosphere gets warmer. This is where EarthCARE comes in.

Launching on 28 May 2024, ESA’s Earth Cloud, Aerosol and Radiation Explorer will help quantify the role that clouds and aerosols play in heating and cooling Earth’s atmosphere. With its suite of four cutting-edge instruments, EarthCARE is a groundbreaking advancement in satellite technology.

It promises to deliver unprecedented data – unravelling the complexities of both clouds and aerosols. With this, we can refine our atmospheric models and climate forecasts, giving us the tools to tackle the challenges of a changing climate with greater accuracy and precision.
