The curious case of Earth's leaking atmosphere 07 July 2016 Earth's atmosphere is leaking. Every day, around 90 tonnes of material escapes from our planet's upper atmosphere and streams out into space. Although missions such as ESA's Cluster fleet have long been investigating this leakage, there are still many open questions. Read more
Cluster is currently investigating the Earth's magnetic environment and its interaction with the solar wind in three dimensions. Science output from Cluster greatly advances our knowledge of space plasma physics, space weather and the Sun-Earth connection and has been key in improving the modeling of the magnetosphere and understanding its various physical processes.
Cluster solves the mystery of equatorial noise 14 July 2015 ESA's Cluster mission has solved a mystery which puzzled scientists for almost half a century. Data sent back by two of the spacecraft have revealed for the first time the physical mechanism behind the generation of "noisy" waves in near-Earth space. Read more
Seven ESA satellites team up to explore Earth's magnetic field 01 July 2015 Cluster and Swarm find evidence of strikingly similar phenomena at different altitudes for the first time, showing a link between Earth's ionosphere and magnetosphere. Read more
Heart of the black auroras revealed by Cluster 09 April 2015 Most people have heard of auroras - more commonly known as the Northern and Southern Lights - but, except on rare occasions, such as the recent widespread apparition on 17 March, they are not usually visible outside the polar regions. Less familiar are phenomena known as black auroras, dark patches which often subdivide the glowing curtains of red and green light. Read more
Origin of high-latitude auroras revealed 18 December 2014 Auroras are the most visible manifestation of the Sun's effect on Earth, but many aspects of these spectacular displays are still poorly understood. Thanks to ESA's Cluster and NASA's IMAGE satellites working together, a particular type of very high-latitude aurora has now been explained. Read more
