INTEGRAL has detected surprisingly powerful X-ray and gamma ray emission from a special class of neutron star, known as Anomulous X-ray Pulsars (AXP), which proves them to be among the most magnetically active bodies known.

On the night of 13 March 1986 the Giotto spacecraft passed within 600 km of the core of comet 1P/Halley. Launched eight months earlier on 2 July 1985, Giotto was the first spacecraft to visit a comet's nucleus and represented ESA's first deep space mission.

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.

On 27 December 2004, radiation from the biggest starquake on a neutron star ever recorded reached Earth. Unique data obtained by Double Star TC-2 and Cluster satellites enabled a group of European scientists to find the first observational evidence of cracks in the neutron star crust, during the initial phase of the starquake. This result, published 16 June 2005 in the Astrophysical Journal, dicriminates between current theories on the physical origin of such massive starquakes.

Observations with the Hubble Space Telescope have revealed the presence of a compact disk of young stars at the heart of the Andromeda galaxy surrounding the central black hole.

In an article to be published in the Astrophysical Journal, Bélanger et al. report on the nature of a hard X-ray source located near and associated with the black hole at the centre of our galaxy.

A number of interesting papers have recently been published based on data gathered by INTEGRAL - ESA's gamma-ray observatory. They cover a range of observations covering all the capabilities of the spacecraft.

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.

A publication in the Annales Geophysicae reports on the first ever measurement of the current density in the ring current region using data from the Cluster spacecraft.

The OMC onboard INTEGRAL was triggered via the INTEGRAL Burst Alert System last week in an attempt to view the optical counterpart to a Gamma-ray Burst. Unfortunately the star alpha Crucis got in the way.

Bertaux et al. report in the science journal Nature that SPICAM observations of the Martian nightside limb have found the first evidence of auroral activity in the Martian atmosphere

Titan possesses a dense atmosphere with a surface pressure of 1.5 bar and with N2 as its main constituent. Methane is the second most important component, but it is photodissociated on a timescale of 107 years. Because methane is still observed in Titan's atmosphere a replenishment process must be taking place through either surface, or subsurface, hydrocarbons.
