2022-09-27 Future Gaia Data releases

27 September 2022The Gaia Data Release 3 (Gaia DR3) released 13 June 2022 covered 34 months of data. Already before this milestone, the processing for future releases had been proceeding. Gaia Data Release 4 (Gaia DR4) will cover 66 months of observations including all data from the nominal mission. In the current schedule the Gaia DR4 is anticipated to take...

2022-09-26 Gaia on the hunt for dual quasars and gravitational lenses

26 September 2022Thanks to its unprecedented combination of excellent resolution and sky coverage, Gaia is now used to study not only stars, but also extremely distant objects such as quasars (QSO). Cosmological models in fact predict the presence of a large population of dual supermassive black holes (SMBH) in a common host galaxy, spiraling closer and closer...

2022-09-23 Shaw prize award ceremony 2022

23 September 2022In May 2022, it was announced that the Shaw Prize in Astronomy was awarded to Lennart Lindegren and Michael Perryman, for their "lifetime contributions to space astrometry, and in particular for their role in the conception and design of the European Space Agency's Hipparcos and Gaia missions."

2022-09-23 Gaia's observation of relativistic deflection of light close to Jupiter

23 September 2022The first observation of the deflection of light in the Solar System was conducted by F. Dyson and A. Eddington in 1919 and verified Einstein’s theory of General Relativity (GR) using observations of several stars close to the Sun. 103 years after that experiment Gaia has revisited relativistic light deflection in the optical, this time around...

8 September 2022To increase the scientific return from its Space Science missions, the European Space Agency welcomes applications from scientists interested in pursuing research projects based on data publicly available in the ESA Space Science Archives. The ESA Archival Research Visitor Programme is open to scientists, at all career levels, affiliated with...

2022-08-11 Gaia reveals the past and future of the Sun

11 August 2022Published now on esa.int/gaia a new story on Gaia's solar analogues, giving insight in the possible past and future of the Sun.

2022-06-24 Gaia DR3 known issue on planetary transits

24 June 2022The Gaia DR3 table named vari_planetary_transit contains information on the period and other properties (transit reference time, depth, duration, etc.) of 41 new planetary transit candidates and 173 known exoplanets (Eyer et al. 2022, Panahi et al. 2022). The data in this table contain serious errors and users are advised not to use them. A...

2022-06-23 Gaia DPAC CU8 webinar

23 June 2022Gaia Data Release 3 contains a wealth of new data products for the community. Astrophysical parameters are a major component of this release. They were produced by the Astrophysical parameters inference system (Apsis) within the Gaia Data Processing and Analysis Consortium. This presentation gives an overview of the over 40 different parameters...
