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.

The Ninth European Announcement of Opportunity for observations to be performed with Suzaku, starting in April 2014, is now open. Scientists belonging to institutions within ESA Member States are invited to respond. The deadline for receipt of proposals is 13 November 2013 at 16:00 CET.

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 have used observations from Hubble's CANDELS survey to explore the sizes, shapes, and colours of distant galaxies over the last 80% of the Universe's history.

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.

The release of a new catalogue from the XMM-Newton space telescope provides an unprecedented cosmic X-ray library for the exploration of the extreme Universe. The third XMM-Newton Serendipitous Source Catalogue (3XMM-DR4) contains more than half a million sources.

Astronomers using the NASA/ESA Hubble Space Telescope have, for the first time, determined the true colour of a planet orbiting another star. If seen up close this planet, known as HD 189733b, would be a deep cobalt blue, reminiscent of Earth's colour as seen from space.

The construction of ESA's Euclid space mission to explore the 'dark Universe' will be led by Italy's Thales Alenia Space as prime contractor, beginning the full industrial phase of the project.

ESA's billion-star surveyor, Gaia, has completed final preparations in Europe and is ready to depart for its launch site in French Guiana, set to embark on a five-year mission to map the stars with unprecedented precision.

The Hubble Space Telescope has produced this vivid image of a pair of interacting galaxies known as Arp 142. When two galaxies stray too close to each other they begin to interact, causing spectacular changes in both objects.

A survey from Herschel has revealed that the reservoir of molecular gas in the Milky Way is hugely underestimated - almost by one third - when it is traced with traditional methods. The discovery not only indicates that there is more raw material for the formation of new stars in the Galaxy, but also that it extends farther than astronomers knew.

The module carrying the telescope and scientific instruments of ESA's Euclid 'dark Universe' mission is now being developed by Astrium in Toulouse, France.

The NASA/ESA Hubble Space Telescope has produced the most detailed observations ever of the Ring Nebula (Messier 57). This image reveals intricate structure only hinted at in previous observations, and has allowed scientists to construct a model of the nebula in 3D - showing the true shape of this striking object.

Astronomers have found a rare encounter between two massive and gas-rich galaxies in a survey from Herschel. The event took place when the Universe was only about three billion years old and involved two galaxies forming stars with exceptional efficiency whilst in the process of merging. This galactic collision would go on to form a very massive...

The NASA/ESA Hubble Space Telescope has found signs of Earth-like planets in an unlikely place: the atmospheres of a pair of burnt-out stars in a nearby star cluster. The white dwarf stars are being polluted by debris from asteroid-like objects falling onto them. This discovery suggests that rocky planet assembly is common in clusters, say...

Observing the Galactic Centre with Herschel, astronomers have detected molecular gas at surprisingly high temperatures - up to 1000 K. The molecules are probably heated up by shocks as gas surges towards Sagittarius A*, the region harbouring the supermassive black hole at the centre of the Milky Way.

The Herschel space observatory has exhausted its supply of liquid helium, after more than three years of observations and revelations about how galaxies, stars, and planets form and evolve. Ground-breaking discoveries are in store for years to come.
