19/12/2018 Reward for Gaia and Anthony Brown

Our Gaia DPAC Chair Anthony Brown is recognised by Nature as one of the 10 people who mattered in 2018. This is a special recognition for Anthony, who keeps the Consortium moving forward to get the data from our Gaia mission out to the community. Read the article here

19/12/2018 Gaia's 5th launch anniversary

Today marks the 5th anniversary of the launch of Gaia into space. Relive this moment by watching the launch event at ESOC from 19 December 2013.

17/12/2018 Video release: the universe of Gaia

Gaia was launched 19 December 2013 and has been scanning the sky ever since. Our second data release, published this April, provided scientists with an extraordinary data set to investigate the formation and evolution history of our Milky Way. Hundreds of scientific studies were performed since, with new papers coming out almost every day.

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.

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.
