14/11/2018 Gaia mission extension approved
Today the ESA Science Programme Committee (SPC) confirmed the Gaia mission extension for mid-2019 to end of 2020 and has given an indicative extension for up to end of 2022. More information can be found here.
07/11/2018 Vacancy: two Phd positions at Lund Observatory
At the Lund observatory, two PhD positions are open in Astronomy and Astrophysics at the Department of Astronomy and Theoretical Physics. One on "Validation and exploitation of Gaia data" and one on "Formation of moon systems".
For the position on "validation and exploitation of Gaia data", the student will participate in the Gaia data processing for future data releases, and more specifically be involved in improving the calibration models as well as characterizing the quality of the catalogue. More information on both positions can be found on our vacancies page and also at the webpages of the Lund Observatory: here and here. Deadline for applications is 1 December 2018.

Research using our Gaia DR2 data has shown our Milky Way galaxy is still enduring the effects of a near collision that set millions of stars moving like ripples on a pond. Read the story here.
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.
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.
