News & Highlights
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.
07/09/2018 Vacancy: ESA Research Fellowships in Space Science
ESA has announced an opportunity for post-doctoral research fellowships linked to its science missions, including Gaia. Deadline to submit applications is 1 October 2018. More details can be found on the ESA Faculty Page and on the ESA Careers webpage.
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.
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.
22/08/2018 Infant exoplanet weighed by Hipparcos and Gaia
An article published in Nature Astronomy discusses the use of Gaia Data Release 2 in combination with Hipparcos data to estimate the mass of the young exoplanet Beta Pictoris b through the astrometric motion of its host star. Read more here.
21/08/2018 Jean Kovalevsky passed away
We are sad to hear that Jean Kovalevsky, one of the key persons that made Hipparcos possible and former chair of the Hipparcos FAST consortium, passed away on Friday 17 August. He was a renowned specialist of celestial mechanics, space geodesy and astrometry.
An obituary, written by François Mignard, can be found here.
01/06/2018 Conference announcement: ESLAB #53 - The Gaia Universe
One year after our second release, Gaia organises a conference at ESTEC (The Netherlands) from 8 to 12 April 2019. By then a wealth of studies will have been completed on a wide variety of topics, joined in their use of Gaia Data Release 2. Mark the date in your calendar. More information on registration will follow after summer.
