03/09/2018 Gaia Data Access - Call for Gaia-DR3 User Scenarios

With the recent release of Gaia DR2, the community is now asked to review the current set of Data Access Scenarios, and submit new data access scenarios, which will be considered for future implementation to support the development of the Gaia Archive system in the release of Gaia DR3 and the following Gaia DR4 release. The data release page gives an indication of the range of Gaia data products currently planned for release in the upcoming data releases.

Your help in describing how you wish to access the Gaia Data through the ESA Gaia archive and/or other access points is very valuable in helping the Gaia project develop and deploy the best possible interfaces and tools to help you, the science community, access and work with the Gaia data.

This call is open until December 2018. Please see the GREAT wiki page for details as to how to add new scenarios.

03/09/2018 Survey on the use of Data-Link for Light Curve Access

A novel interface for distributing light curves has been introduced in Gaia Data Release 2. The infrastructure used is based on a combination of the DataLink Virtual Observatory protocol and an ad-hoc web service - see this tutorial page for further details.

We have created a survey in order to collect user experience on this interface, and gather requirements for its evolution toward the Data Release 3 and beyond. The survey can be accessed through this link.

Feedback on the use of Data-Link is valuable in planning and preparing for publication of larger numbers of light curves in future Gaia data releases.

27/08/2018 Gaia DR2 Known Issues

A new page dedicated to discuss some known issues with the Gaia DR2 data is available here. These cover issues that are important for the users to be aware of but that were only discovered after the release of the data and the documentation. Keep an eye out for the page as newly found issues will be published there when needed.

24/08/2018 Gaia Data Release scenario

The schedule leading to Gaia DR3 remains uncertain given that many new elements in the processing chain will be operational for the first time. A better knowledge of the schedule will be available in the course of 2019, but it is clear that a release by the end of 2020 will be challenging and a delay to the first half of 2021 seems likely. In order to inform the community of this uncertainty, the Gaia Data Release Scenario page has been updated accordingly.

30/09/2017 Gaia mission helps with Triton occultation observations

On Thursday 5 October an important and rare astronomical event will take place: Triton will be occulting a star (called UCAC4 410-143659 or GaiaDR2 2610107907030969600). This stellar occultation will be visible from Europe across the Atlantic to the USA. A predicted occultation path has been computed using the preliminary Gaia DR2 position and proper motion for this star.

The Triton position can, however, still be improved. In order to maximise the scientific output of the occultation event, we have decided to release astrometry for 119 stars in the field surrounding Triton at this moment. The most suitable stars between magnitudes 12 and 17 have been chosen for astrometric calibration purposes. Please note that full validation of the data is not yet done and therefore some caution is required when interpreting the results. Nevertheless, we believe the data will allow improvement of the occultation prediction.

Scientists using these data to improve Triton astrometry are encouraged to make their deduced positions public so that science return can be maximised for all groups observing the event. Please keep us informed of your efforts and results in this topic.

The 119 stars are available for download through the links below:

When using these data, please follow the acknowledgment and citation guidelines as given here.

Good luck with the observations!

08/09/2017 Young Astronomer School on the Scientific Exploitation of the Gaia Data

The Doctoral School of Astronomy and Astrophysics of Paris and the Observatoire de Paris are organizing an international school for PhD and post-doctoral students on the scientific exploitation of the Gaia data and the study of the stellar populations of our Galaxy. It will be held in Paris (FIAP, Paris 14ème) from 26 February to 2 March 2018.

The school will propose lectures given by internationally recognized experts in the study of the formation and evolution of the Milky Way and will be accompanied by hands-on sessions. The school will allow the participants to master the knowledge and tools allowing them to manipulate and to explore the Gaia catalog and to derive properties necessary for the analysis of stellar populations, such as the age of stars, their orbits in the Galaxy, etc.

The application deadline is November 30, 2017, but the attendance is limited to 40-50 students and candidates are therefore strongly encouraged to apply as soon as possible. More information is available here.

23/06/2017 Two Arthur C. Clarke Awards for Gaia teams

We are proud to announce that our Gaia teams won two Arthur C. Clarke awards, also known as Arthurs. The Industry/Project Team award went to Airbus Defence and Space "For the successful design and manufacture of the Gaia spacecraft and telescope which for the last 3 years has been accurately measuring the location and motion of the stars”.

The second award was given to the UK Gaia Science Team. They won the Space Achievement - Academic Study/Research award "For its role in processing and analysing data from the Gaia star mapping mission as its contribution to the European Data Processing and Analysis Consortium”.

This latter award was presented by UK/ESA Astronaut Tim Peake to Gerry Gilmore (UK Gaia PI), Martin Barstow and Simon Hodgkin, who received it on behalf of the wider UK team. The award is made of glass, and is based on the monolith in Clarke’s 2001: A Space Odyssey, with the same proportions (1:4:9).

20/06/2017 Celebrating 20 years of astrometric data from space

Almost 300 astronomers and astrophysicists from all over the world gathered in Venice on 13-16 May 1997 at the Hipparcos Venice 97 Symposium, organised by the European Space Agency. This symposium marked the public release of the Hipparcos and Tycho Catalogues, which took place in June 1997, twenty years ago.

The parallaxes and proper motions of the 117,955 stars contained in the Hipparcos Catalogue have meanwhile generated more than 2,400 refereed articles. Hipparcos laid the foundation for the Gaia mission and was the first space mission dedicated to measure the positions of stars. While Hipparcos gave access to data on 117,995 stars, Gaia is to deliver astrometry for more than 1 billion objects in April 2018.

This a subset of Gaia DR1 consisting of those stars in the Hipparcos and Tycho-2 Catalogues for which a full 5-parameter astrometric solution is available.

In April another video was published showing the movement of the stars in the entire sky.

23/05/2017 Three stellar positions released to support unique occultation events
