07/12/2018 Gaia Parameter Database is back up

The Gaia Parameter Database is back up and working.

06/12/2018 Password reset required for all Gaia users from 6 December 2018 onwards.

From today forward, you will need to reset your password to be able to continue using Gaia services. If you experience problems accessing the Gaia Archive, Gaia Cosmos or Gaia DPAC services, please go to the Gaia Cosmos portal and follow the password reset process. Go to the top right corner and click on the sign in button. Then follow the path "Forgot your password?". You will receive a link at your email connected to your Gaia Cosmos account to reset your password. In case you are experiencing problems, please contact the Gaia Helpdesk.

Soon we will send out an extra message about the full procedure to follow.

Please be aware that access to SVN is synchronised with a delay of about 15 minutes. After the password reset, allow for some time before accessing SVN.

28/11/2018 Opening for a Gaia DPAC postdoc position at Leiden Observatory

The postdoc position will focus on crowded field (spectro-)photometric data processing for the Gaia mission. Specifically, the work will result in algorithms and code, to be integrated into the DPAC processing pipeline, for the combination of repeated observations of blended sources in order to disentangle the overlapping Blue and Red Photometer prism spectra. The work will be guided by insights gained from a limited set of full frame images of crowded fields obtained with Gaia's Skymapper CCDs through the Service Interface Function (SIF). More information here.

19/11/2018 Young Graduate Trainee Opportunities

Interested in a traineeship at ESA? Read about the Young Graduate Trainee Opportunities here. Applications are now open until 16 December. One of the trainee opportunities is related to Gaia: YGT for Astrophysics.

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.

02/10/2018: Gaia spots stars flying between galaxies

A team of astronomers using Gaia Data Release 2 looked for high-velocity stars being kicked out of the Milky Way were surprised to find stars instead sprinting inwards – perhaps from another galaxy. Read the story here.

19/09/2018 Gaia hints at our Galaxy's turbulent life

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.
