Today the Gaia Mission celebrates the second anniversary of Gaia Data Release 2. The Gaia catalogues have been embraced by many scientists across the world. Today, we are proud of the many papers that appeared using our latest release, Gaia DR2. In the past 2 years, almost 3000 refereed papers based on Gaia Data Release 2 have been published. That amounts on average to 4 papers per day. Thank you for using our data with so much enthusiasm! In the meantime, ESA Gaia teams and Gaia DPAC are continuously working towards next data releases. Keep posted with our Gaia newsletter of upcoming releases.

 

Gaia's first release came out on 14 September 2016. On 25 April 2018, the Gaia Collaboration published its second date release.

 

06/03/2020 Gaia's latest science stories

Milky Way's warp caused by Galactic collision, Gaia suggests: Astronomers have pondered for years why our galaxy, the Milky Way, is warped. Data from ESA's star-mapping satellite Gaia suggest the distortion might be caused by an ongoing collision with another, smaller, galaxy, which sends ripples through the galactic disc like a rock thrown into water. Further reading here.

Global Gaia campaign reveals secrets of stellar pair: A 500-day global observation campaign spearheaded more than three years ago by ESA’s galaxy-mapping powerhouse Gaia has provided unprecedented insights into the binary system of stars that caused an unusual brightening of an even more distant star. Further reading here.

26/09/2019 Update to the Gaia data release scenario

Data processing toward Gaia (E)DR3 continues to progress within the announced schedule. However, to ensure sufficient quality of the quasars and extended objects results, an additional processing run has to be scheduled moving their outcome from Gaia EDR3 to Gaia DR3. Another modification concerns a new data product. A pencil beam survey with (integrated) epoch photometry of all sources (variable and non-variable) will be added to Gaia DR3. The selected field is centred on the Andromeda Galaxy. The cone with 5.5 degree radius contains in total about 1 million sources both in M31 and the Milky Way. In order not to impact the release schedule, only a limited amount of explicit validation will be done on the pencil beam epoch photometry.

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:
- radial velocities (significantly more due to fainter magnitude limit),
- BP/RP/RVS spectra (new products),
- Solar system data (significantly more sources included),
- variability information (significantly more objects due to longer time interval),
- results for non-single stars (new products), and
- astrophysical parameters (based on spectra).
The final inclusion of the products into Gaia DR3, as well as Gaia EDR3, is subject to successful validation.

30/09/2017 Gaia mission helps with Triton occultation observations

On Thursday 5 October an important and rare astronomical event will take place: Triton will be occulting a star (called UCAC4 410-143659 or GaiaDR2 2610107907030969600). This stellar occultation will be visible from Europe across the Atlantic to the USA. A predicted occultation path has been computed using the preliminary Gaia DR2 position and proper motion for this star.

The Triton position can, however, still be improved. In order to maximise the scientific output of the occultation event, we have decided to release astrometry for 119 stars in the field surrounding Triton at this moment. The most suitable stars between magnitudes 12 and 17 have been chosen for astrometric calibration purposes. Please note that full validation of the data is not yet done and therefore some caution is required when interpreting the results. Nevertheless, we believe the data will allow improvement of the occultation prediction.

Scientists using these data to improve Triton astrometry are encouraged to make their deduced positions public so that science return can be maximised for all groups observing the event. Please keep us informed of your efforts and results in this topic.

The 119 stars are available for download through the links below:
