Gaia tops one trillion observations

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...
