TL;DR: Gaia as discussed by the authors is a cornerstone mission in the science programme of the European Space Agency (ESA). The spacecraft construction was approved in 2006, following a study in which the original interferometric concept was changed to a direct-imaging approach.

TL;DR: In this article, the first parallax measurements of the primary standard candles of the cosmological distance ladder, that involve astrometry collected by Gaia during the initial 14 months of science operation, are published in Gaia Data Release 1 (DR1) as part of the Tycho-Gaia Astrometric Solution (TGAS).

TL;DR: In this paper, a robust principal component analysis framework for the exploitation of multiband photometric measurements in large surveys is proposed, where period search results are improved using the time-series of the first principal component due to its optimized signal-to-noise ratio.

TL;DR: The ISDC is designed as an interface between the INTEGRAL data and the user community to detect GRBs and other bright transient sources, and produce and archive a set of standard data products, and to distribute them to the observers.
