Monday, 11 August 2008, Cassini will visit Enceladus to obtain the highest resolution images to date of the moon's enigmatic south polar region with its tiger stripes. Closest approach occurs at 21:06:19 UTC at an altitude of just 54 kilometres. This is Cassini's fifth close fly-by of Enceladus and the trajectory - taking it over both the...

Just over two months after its last visit, the Cassini spacecraft once again approaches Titan for the mission's forty-sixth targeted encounter with the large Saturnian moon. This is the first Titan encounter in Cassini's Equinox Mission. The closest approach to Titan occurs on Thursday, 31 July, at 02:13:11 UT at an altitude of 1613 kilometres...

A nova explosion is usually detected first at optical wavelengths. The recent nova V598 Puppis, although being among the brightest novae, was instead discovered first in X-rays by XMM-Newton, some four months after the optical emission had peaked

The pericentre altitude of the Venus Express orbit is being lowered by a series of manoeuvres over a nearly four-week period with the spacecraft reaching a minimum altitude of 185 km in August. This will provide new science opportunities for the mission.

XMM-Newton observations of the unique double pulsar system PSR J0737-3039 have confirmed pulsed X-ray emission from one component and, for the first time, provided strong evidence for X-ray emission from the second pulsar. The XMM-Newton data show that this unusual system displays complex X-ray behaviour.

Some of the most explosive phenomena in the Universe are due to a physical process known as magnetic reconnection. Fundamental aspects of this process are still not fully understood but new advances, using Cluster data, have recently been reported by a team led by scientists from the Chinese Academy of Sciences.
