Mission complete: Rosetta’s journey ends in daring descent to comet

Fri, 30 Sep 2016 10:19:00 UT

ESA’s historic Rosetta mission has concluded as planned, with the controlled impact onto the comet it had been investigating for more than two years.

Rosetta measures production of water at comet over two years

Tue, 27 Sep 2016 12:49:00 UT

Over the past two years, Rosetta has kept a close eye on many properties of Comet 67P/Churyumov-Gerasimenko, tracking how these changed along the comet's orbit. A very crucial aspect concerns how much water vapour a comet releases into space, and how the water production rate varies at different distances from the Sun. For the first time, Rosetta enabled scientists to monitor this quantity and its evolution in situ over two years.

Summer fireworks on Rosetta's comet

Fri, 23 Sep 2016 19:09:00 UT

Brief but powerful outbursts seen from Comet 67P/Churyumov–Gerasimenko during its most active period last year have been traced back to their origins on the surface.

Hubble helps find light-bending world with two suns [heic1619]

Thu, 22 Sep 2016 13:27:00 UT

A distant planet orbiting two stars, found by its warping of spacetime, has been confirmed using observations from the NASA/ESA Hubble Space Telescope. The planet's mass caused what is known as a microlensing event, where light is bent by an object's gravitational field. The event was observed in 2007, making this the first circumbinary planet to be confirmed following detection of a microlensing event.

Gaia's billion-star map hints at treasures to come

Tue, 13 Sep 2016 13:32:00 UT

The first catalogue of more than a billion stars from ESA's Gaia satellite was published today – the largest all-sky survey of celestial objects to date.

Call for Media: Rosetta's grand finale

Fri, 09 Sep 2016 10:16:00 UT

Rosetta is set to complete its mission in a controlled descent to the surface of its comet on 30 September.

XMM-Newton Announcement of Opportunity (AO-16)

Tue, 23 Aug 2016 09:48:00 UT

Proposals are solicited for observations with XMM-Newton in response to the sixteenth Announcement of Opportunity, AO-16, issued 23 August 2016. This AO covers the period May 2017 to April 2018 and is open to proposers from all over the world.

Cosmic explosions: the first ESA–Ars Electronica residency

Wed, 03 Aug 2016 09:48:00 UT

Aoife van Linden Tol, an artist working primarily with explosive media, is the recipient of the first art&science@ESA residency, organised by Ars Electronica in partnership with ESA.

Call for a Medium-size mission opportunity in ESA's Science Programme (M5)

Fri, 29 Apr 2016 08:06:00 UT

Through this Call for Missions the Director of Science solicits from the broad scientific community proposals for the competitive selection of mission concepts to be candidate for the implementation of a medium-size, or M-class, mission (M5).

Announcement of Opportunity for new science ideas in ESA's Science Programme

Tue, 09 Feb 2016 07:30:00 UT

This Call solicits proposals for the competitive selection of new science ideas, to be investigated in terms of feasibility and needed technology developments. The deadline for the submissions of proposals is 14 September 2016, at 12:00 (noon) CEST. Proposals must be preceded by a mandatory Letter of Intent to be received by 9 May 2016, at 12:00 (noon) CEST.
