On 14 April 2018, about 10 days before the second Gaia Data Release, the spacecraft and daily data processing systems have reached yet another stunning milestone: the number of star transits has reached 100 billion! The Gaia satellite has two telescopes pointing to two regions of the sky separated by 106.5 degrees. The satellite spins at a rate of 6 hours per revolution with the two telescopes scanning a great circle and the stars continuously transiting the focal plane. Every day, Gaia instruments record about 70 million transits. A full transit includes an observation in the sky mapper (to...

The Gaia group at the Universitat de Barcelona (IEEC – ICCUB), in cooperation with DAPCOM Data Services S.L. (a technological spin-off company of the UPC and the UB), has published an alternative copy of the bulk data files from Gaia DR2 – the second data release from Gaia. Gaia DR2 was published on 25 April 2018. Besides the on-line catalogue, bulk CSV files were also made available for download – an interesting option for exhaustive analyses. Such files are officially offered in “csv.gz” format, that is, compressed with the widely known gzip compressor. On 6...
