Attention #GaiaData users: Gaia data release 4 (#GaiaDR4) is planned for 2 December 2026. This data release is the first principal data release of the Gaia mission, covering data collected during the first 5.5 years of observations. More details: cosmos.esa.int/web/gaia/data-…
- Replying to @ESAGaia and @UniBarcelonaSo far, #GaiaDR3 is based on 3 years of data, while Gaia observed the sky for 10,5 years. So the best is yet to come! #GaiaDR4 will be based on 5,5 years of data. The first full release for the Gaia mission, with all intended data products: cosmos.esa.int/web/gaia/data-…
GIF - Replying to @ESAGaiaThis year, in March, the Gaia spacecraft was sent into its retirement orbit. A video was prepared by @UniBarcelona in the framework of the ERC project Visual Trust: visualtrust.ub.edu on this emotional day: youtube.com/watch?v=dduXM5…
- Replying to @ESAGaiaOur Gaia Collaboration #GaiaDPAC is hard at work to process, validate and document Gaia Data Release 4. While #GaiaDR3 brought ~60 different data products, #GaiaDR4 will bring ~130 of them. Lots of new data products! Updated page 👉cosmos.esa.int/web/gaia/dr4
- On this day, 12 years ago, Gaia was launched into space. 2 years ago, we celebrated Gaia's 10 years in space: cosmos.esa.int/web/gaia/iow_2… and this lovely video was made: youtube.com/watch?v=l8EBuZ…
- Replying to @ESAGaia and @esaGaia Data Release 4 is expected December '26 and #GaiaDPAC is hard at work processing, validating & documenting the data sets. While #GaiaDR3 brought ~60 different data products, #GaiaDR4 will bring ~130 of them. Lots of new data products! Updated page 👉cosmos.esa.int/web/gaia/dr4
- Replying to @ESAGaiaAn interactive image release was published today by @esa 👉 esa.int/ESA_Multimedia…. Explore each of the 31 baby star systems. All systems with a very young star at the centre that recently collapsed from clouds of gas and dust.
- Ever wondered how planetary systems like our own Solar System form? Thanks to Gaia's astrometric information, hints of unseen companions were detected in 31 baby star systems. @almaobs shows us what they look like. The solar system (bottom right) is shown as reference.
- A look behind the scenes: switching off the Gaia spacecraft. On 27 March 2025, this emotionally charged milestone marked the end of spacecraft operations, though not the end of the mission! #GaiaDR4 is expected in Dec 2026 🔭cosmos.esa.int/web/gaia/iow_2… youtu.be/dduXM5FbpcY
