In a dedicated Nature paper, T. Phan et al. shed light on the nature and scale of the magnetic reconnection process, based on Cluster, ACE and WIND observations.

Over the past five years, a series of discoveries by the multi-spacecraft Cluster mission have significantly enhanced our knowledge of how, where and under which conditions killer electrons are created in the Earth's magnetospheric environment. During intense magnetic storms (driven by enhanced solar activity) highly energetic electrons (the so-called killer electrons) are often responsible for permanently damaging satellites and pose a serious hazard to astronauts.

The Double Star TC-2 and Cluster satellites have gathered unique data from the biggest starquake on a neutron star ever recorded, enabling the discrimination between current theories on the origin of these type of events.

Thanks to measurements by ESA's Cluster mission, a team of European scientists have identified 'micro' -vortices in Earth's magnetosphere. Such small-scale vortex turbulence, whose existence was predicted through mathematical models, has not been observed before in space. The results are not only relevant for space physics, but also for other applications like research on nuclear fusion.

The 16 July 2005 marks the 5th anniversary of the launch of the first two Cluster satellites from Baikonur. It also coincides with the end of two months of successful manoeuvres in space for the four spacecraft of the Cluster mission.

New results from simulations based on Cluster data are providing insight in the processes that transfer solar wind plasma into the Earth's magnetotail when the Interplanetary Magnetic Field is strongly northward oriented.

On 10 February, the ESA Science Programme Committee approved unanimously the extension of the Cluster mission, pushing back the end date from December 2005 to December 2009.

Multipoint measurements from the Cluster spacecraft have revealed, for the first time, a direct observation of a three dimensional geometry for a hitherto unexplained type of magnetic reconnection.

A study based on the multipoint measurements of the Cluster spacecraft provides new details on the typical size of the spectacular transient high-speed plasma flows in the Earth's magnetotail.

A recent study based on Cluster data has provided new insights into an existing technique to determine the type of an interplanetary magnetic field discontinuity and sheds light on the solar wind dynamics.

During the 8th Cluster joint ESA-NASA workshop, several key topics were discussed in four working groups, covering the important physical processes in the Earth's magnetosphere and the plasma environment of near Earth space.

A multipoint analysis of Cluster data allows, for the first time, to locate the source of NTC radiation, triggering the need for more detailed generation and propagation models to explain new findings.

ESA's Cluster spacecraft has discovered vortices of ejected solar material high above the Earth. The superheated gases trapped in these structures are probably tunnelling their way into the Earth's magnetic 'bubble', the magnetosphere.

Recent statistical studies of Cluster data have provided new insights into the origin of rapid large-amplitude magnetic variations in the centre of the Earth's magnetotail.

On 18 April 2002, three cusps were consecutively observed by Cluster over the northern hemisphere. A detailed study reveals that this triple cusp was a temporal sequence rather than a spatial effect.

Cluster's unique capability for multipoint measurements has provided new insights into the thickness of the Earth's bow shock with broad relevance to collisionless shocks in astrophysics.

About 40 Cluster scientists gathered recently for a workshop investigating phenonmena associated with the Earth's magnetotail.

On the 24th of October 2003, the SOHO spacecraft registered a huge Coronal Mass Ejection (CME), emitted by the Sun. Several hours later this eruption reached the Earth and was detected by a number of spacecraft including Cluster.
