2022-11-25 100 months of Gaia data

25 November 2022The Gaia science operations started on the 25th of July 2014, when the spacecraft was turned on in science mode, following the completion of the in-flight commissioning. This 25 November 2022 marks the 100 months of data collection, with a regular daily flow of an average of 70 million new on-board detections and a single significant...

2022-11-23 The astonishment

23 November 2022The Gaia mission has many scientific goals: to increase our understanding of the Milky Way, to create the best map so far of our galaxy, and more. But one important aspect of science missions in general is to inspire. Inspiration can lead to the greatest discoveries and the most beautiful ideas spring to mind. One such project, called "Gen...

2022-11-17 Gaia Photometric Science Alerts at risk

17 November 2022The Gaia Photometric Science Alerts consists of a pipeline feeding candidate transients into a web portal. This allows the community to follow up on potentially interesting events seen by Gaia immediately following observations taken. Currently, these Gaia Alerts are at risk due to a combination of factors. More info can be found from the news...

2022-11-09 Gaia Collaboration to receive 2023 Berkeley Prize

2022-11-09 Gamma-Ray Burst detection from L2 by Gaia

9 November 2022Gaia is the European Space Agency's astrometric mission to map the Milky Way galaxy in unprecedented detail. The spacecraft has no dedicated particle detection instrumentation but is however able to measure the particle flux at the focal plane by counting the ionization tracks due to the passage of charged particles. On 9 October 2022 an...
