Tangled threads weave through cosmic oddity [heic1621]

Thu, 01 Dec 2016 14:10:00 UT

New observations from the NASA/ESA Hubble Space Telescope have revealed the intricate structure of the galaxy NGC 4696 in greater detail than ever before. The elliptical galaxy is a beautiful cosmic oddity with a bright core wrapped in system of dark, swirling, thread-like filaments.



Two-year extensions confirmed for ESA's science missions

Tue, 22 Nov 2016 14:36:00 UT

ESA's Science Programme Committee (SPC) has today confirmed two-year mission extensions for nine scientific missions in which the Agency is participating. This secures their operations until the end of 2018.



Icy surprises at Rosetta's comet

Thu, 17 Nov 2016 19:00:00 UT

As Rosetta's comet approached its most active period last year, the spacecraft spotted carbon dioxide ice – never before seen on a comet – followed by the emergence of two unusually large patches of water ice.



Mars' ionosphere shaped by crustal magnetic fields

Thu, 03 Nov 2016 08:04:00 UT

Scattered pockets of magnetism across the surface of Mars have a significant influence on the planet's upper atmosphere, according to observations from ESA's Mars Express. Understanding these effects may be crucial for ensuring safe radio communications between Mars and Earth and, eventually, between explorers on the surface of the planet.



Follow the Gaia 2016 Data Release #1 Workshop live

Fri, 28 Oct 2016 10:46:00 UT

On 2-4 November, the European Space Astronomy Centre near Madrid, Spain, will host the Gaia 2016 Data Release #1 Workshop. Many of the talks will be broadcast live.



Gaia spies two temporarily magnified stars

Thu, 27 Oct 2016 14:53:00 UT

While scanning the sky to measure the position of over one billion stars in our Galaxy, ESA's Gaia satellite has detected two rare instances of stars whose light was temporarily boosted by other celestial objects passing across their lines of sight. One of these stars is expected to brighten again soon. Gaia's measurements will be instrumental to learn more about the nature of these 'cosmic magnifying glasses'.



Next step towards a gravitational-wave observatory in space

Tue, 25 Oct 2016 14:23:00 UT

Today, ESA has invited European scientists to propose concepts for the third large mission in its science programme, to study the gravitational Universe.



The LISA Pathfinder Science Archive is online

Fri, 07 Oct 2016 10:24:00 UT

Today, ESA's LISA Pathfinder Science Archive opens its virtual gates to the world. It contains data collected by the satellite during the mission's first few months, covering the nominal operations phase of the LISA Technology Package (LTP) – the European payload on LISA Pathfinder.



Cosmic explosions: the first ESA–Ars Electronica residency

Wed, 03 Aug 2016 10:48:00 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.
