The first instrument to be completed for the James Webb Space Telescope, MIRI, was handed over by the European consortium that built it to ESA at a ceremony held in London today, and will now be delivered to NASA aiming for launch in 2018.

The chance discovery with ESA's INTEGRAL observatory, in 2004, of highly energetic X-rays emanating from a young neutron star with an extremely strong magnetic field, provided scientists with a challenge: to explain how these objects, also known as magnetars, produce such energetic non-thermal radiation. A new, comprehensive study of one...

New Herschel images reveal the debris disc around the star Fomalhaut in its full glory. By probing the glow of dust in the disc, these data suggest that it consists of 'fluffy' aggregates of dust grains produced by cometary collisions.

An agreement was signed by ESA and the Japanese Aerospace Exploration Agency (JAXA) for cooperation on Astro-H, an important mission that will provide a unique opportunity to investigate the structure of the Universe and its evolution.

Sub-millimetre observations of 2M1207, a brown dwarf with its own circumstellar disc and a planetary companion five times more massive than Jupiter, reopen the debate on how giant planets form around stellar and sub-stellar objects.

Astronomers have discovered that black-hole driven ultra-fast outflows are common in active galaxies, and they are massive and powerful enough to provide the feedback required by galactic evolution models.

Observations by the NASA/ESA Hubble Space Telescope have come up with a new class of planet, a waterworld enshrouded by a thick, steamy atmosphere. It's smaller than Uranus but larger than Earth.

The scientific community is invited to participate in the Euclid mission by responding to the present Announcement of Opportunity (AO). This AO solicits proposals for the appointment of the second Independent Legacy Scientist in the Euclid Science Team. The deadline for submission of proposals is 12 April 2012, 12:00 CET.

Hubble has imaged the barred spiral galaxy NGC 1073. Our own galaxy, the Milky Way, is a similar barred spiral, and the study of galaxies such as NGC 1073 helps astronomers learn more about our celestial home.

Astronomers have resolved, for the first time, the Vela pulsar wind nebula in the hard X-ray band and have exploited a special imaging technique to reveal a never-before-seen component of the source.
