News & Highlights |
| 15/02/2019 Opening for a software developer in the Gaia Barcelona research team The Gaia team of the Universitat de Barcelona (IEEC – ICCUB) has an opening for a software developer. This team is involved in the simulations and data processing of astrometric and photometric data from the Gaia satellite, and is responsible of the Barcelona Data Processing Center, located in the Marenostrum supercomputer. More information on this vacancy can be found here. |
| 08/02/2019 Gaia clocks new speeds for Milky Way-Andromeda collision Today a new story was released on two nearby galaxies for which the stellar motions within them was determined with the use of Gaia data. The result discussed how they will one day interact and collide with the Milky Way. Read more here. |
| 01/02/2019 Scientific programme of "The Gaia Universe" announced The scientific programme of the 53rd ESLAB symposium 'the Gaia universe' is now online. Participants taking part in the pitch sessions can also review the schedule here. Next to oral presentations and pitch sessions, two poster sessions are held.

| 31/01/2019 Update to Gaia DR2 known issues page on radial velocities Today on ArXiv a paper appeared by Boubert et al. describing potential contamination of radial velocities in crowded regions. A summary has been added to our Gaia DR2 Known Issues page, along with links to the paper and the accompanying data. The page also describes other topics like astrometry and crossmatches, and complements the Gaia DR2 data release documentation. |
| 29/01/2019 Gaia Data Release 3 split into two parts The Gaia data processing toward Gaia DR3 is progressing at full speed. Although the schedule has stabilised, there are several uncertainties as many elements of the pipelines will see the real data in an operational environment for the first time. Taking the uncertainties into account brought the schedule of the next release toward the end of the earlier announced period of the first half of 2021. To mitigate the impact on research, the Gaia DR3 will be split into two releases. This way, data that is ready earlier, will be released earlier. The early release, Gaia EDR3, contains astrometry and (integrated) photometry i.e. positions, parallaxes, proper motions, G-band fluxes as well as integrated red- (RP) and blue-band (BP) fluxes, all based on 34 months of data resulting in better accuracy with respect to Gaia DR2. First results for a predefined list of quasars and extended objects may also be included already in the early release. Gaia EDR3 will take place in Q3 of 2020. Gaia DR3, which is anticipated to take place during the second half of 2021, will supersede Gaia EDR3. This means that the source list and any data published in Gaia EDR3 will not change, but is simply copied to Gaia DR3. Therefore Gaia DR3 is based on the same 34 months of mission data as for Gaia EDR3. The additional products include: |
| 21/01/2019 Gaia newsletter An email was sent out recently to Gaia newsletter subscribers with instructions on how to keep receiving the Gaia newsletter. These instructions are explained on this page in more detail, with some answers to frequently asked questions. |
| 29/12/2018 Movement of tiny galaxies surrounding the Milky Way New animation shows the movement of tiny galaxies surrounding the Milky Way as described in a recent story. An interactive version is available here. |
| 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 |
| 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. |
