An international team of astronomers has found the most distant gravitational lens yet - a galaxy that, as predicted by Albert Einstein's general theory of relativity, deflects and intensifies the light of an even more distant object.

The NASA-ESA-ASI Cassini spacecraft has been observing the Saturn system, including the giant satellite Titan, for more than 9 years. A detailed analysis of Cassini data has now confirmed predictions that the density of Titan's ionosphere is directly linked to the 11 year cycle of solar activity.

Cosmologists have achieved a first detection of the long-sought B-modes in the polarised Cosmic Microwave Background. The result is based on the combination of data from the South Pole Telescope and ESA's Herschel Space Observatory. This detection is a milestone along the way to the possible discovery of gravitational waves produced in the very...

For the past decade, ESA's Mars Express orbiter has been observing atmospheric structure on the Red Planet. Among its discoveries is the presence of three separate ozone layers, each with its own characteristics. A new comparison of spacecraft data with computer models explains how global atmospheric circulation creates a layer of ozone above...

For the first time, astronomers have caught a pulsar in a crucial transitional phase that explains the origin of the mysterious millisecond pulsars. The discovery was made possible by the coordinated efforts of ESA's two missions that scan the high-energy sky: INTEGRAL and XMM-Newton.

Near-Earth space is populated by charged particles - electrons and ions - which occupy regions known as the plasmasphere and the Van Allen radiation belts. Over the past decade, the four identical spacecraft of ESA's Cluster mission have made numerous studies of these regions, and a recent paper has revealed intriguing links between these...

ESA has completed the Near-Infrared Spectrograph, one of two instruments it is contributing to the international James Webb Space Telescope, a space observatory set for launch on an Ariane 5 rocket in 2018.

Astronomers have used the NASA/ESA Hubble Space Telescope and ESO's New Technology Telescope to explore more than 100 planetary nebulae in the central bulge of our galaxy. They have found that butterfly-shaped members of this cosmic family tend to be mysteriously aligned - a surprising result given their different histories and varied properties.

Proposals are solicited for observations with XMM-Newton in response to the thirteenth Announcement of Opportunity, AO-13, issued 27 August 2013. This AO covers the period May 2014 to April 2015 and is open to proposers from all over the world. The deadline for receipt of proposals is Friday, 11 October 2013, 12:00 UT.

Astronomers using ESA's XMM-Newton have measured the magnetic field in a small surface feature of a magnetar for the first time. Until now, only the dipolar magnetic field of magnetars had been measured. With a new technique, the astronomers have revealed a strong, localised magnetic field in the magnetar that had the lowest dipolar field of all.

Astronomers using the NASA/ESA Hubble Space Telescope have solved the 40-year-old mystery of the origin of the Magellanic Stream, a long ribbon of gas stretching nearly halfway around the Milky Way.

Some galaxies hit a point in their lives when their star formation is snuffed out, and they become "quenched". Quenched galaxies in the distant past appear to be much smaller than the quenched galaxies in the Universe today. This has always puzzled astronomers - until now.
