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...

From 16 to 20 November 2015, about two hundred members of the Gaia Data Processing and Analysis Consortium (DPAC) are meeting in Leiden, The Netherlands, to review the current status of preparations for future catalogue releases from ESA’s billion star surveyor mission. Launched in December 2013, ESA’s Gaia satellite started routine scientific operations on 25 July 2014. As it scans the sky from its location at the L2 Lagrange point, Gaia records the position, brightness, and colours of any object brighter than 20th magnitude that crosses its field of view. During its five-year...

Gaiaverse is a dissemination portal on the ESA Gaia’s mission developed within the GENIUS project, a European project funded by the European Commission to boost the impact of the next European breakthrough in astrophysics, the Gaia astrometric mission. GENIUS aims at becoming a hub of Gaia’s spreading knowledge by collecting all kind of divulgation materials such as presentations, videos, posters, brochures, tools, news… which are all available through this portal, Gaiaverse.

Media: ESA (European Space Agency) Title: Celebrity comet spotted among Gaia’s stars Publication date: 3 November 2015 A local cosmic celebrity was recently pictured among the multitude of stars and Solar System bodies surveyed by ESA’s Gaia satellite: Comet 67P/Churyumov–Gerasimenko, currently accompanied by another ESA spacecraft, Rosetta. While scanning the sky to map the positions and motions of a billion stars in our Galaxy, Gaia also picks up objects much closer to home, such as asteroids and comets in the Solar System. With its ability to detect faint and moving objects, Gaia has...
