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
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.
Working life extensions for ESA’s science missions 20 November 2014 Continuing operations of ten space science missions have been extended by ESA’s Science Programme Committee (SPC). Read more
A mixed-up magnetic storm 28 August 2014 The Sun is a variable star, experiencing 11-year-long cycles of activity which impact our planet and near-Earth space. Forecasting the changing space weather and the effects it will have on Earth remains a challenge, as illustrated by an unusual magnetic storm that was observed by ESA's Cluster quartet and one of the Chinese-ESA Double Star spacecraft.

Cluster helps to model Earth's mysterious magnetosphere 07 May 2014 For many years, scientists have been striving to understand the constantly changing structure and behaviour of the huge magnetic bubble that surrounds our planet. One approach – pioneered by Russian scientist Nikolai Tsyganenko - has been to develop models based on data sent back by spacecraft, such as ESA's Cluster quartet. Read more
2nd Announcement of Opportunity for Cluster Guest Investigators 17 February 2014 This AO solicits special operation proposals for participation in the Guest Investigator Programme of the Cluster extended mission from the European Space Agency. Investigations are solicited which identify compelling utilization of the Cluster spacecraft payload for scientific study, for the period 2015-2016. The extended deadline for proposal submissions is 4 June 2014, 23:59 CEST. Read more
