A 500-day global observation campaign spearheaded more than three years ago by ESA’s galaxy-mapping powerhouse Gaia has provided unprecedented insights into the binary system of stars that caused an unusual brightening of an even more distant star.

Nov 3, 2020 · Gaia is an ambitious mission to chart a three-dimensional map of our Galaxy, the Milky Way, in the process revealing the composition, formation and evolution of the Galaxy.

Nov 2, 2020 · The Gaia focal plane will be the largest ever developed, with 106 CCDs, a total of almost 1 Gigapixels and physical dimensions of 0.5m × 1m. The focal plane assembly is common to both telescopes and serves five main functions (in order of occurrence):

ESA's Gaia mission has one main goal, to map the Milky Way more extensively and with greater precision than any other mission to date. Using astrometry, the science of measuring the distance and motion of stars, Gaia will map a billion stars over a 5 year period to produce a comprehensive catalogue of measurements that will impact on most areas ...

Sep 1, 2019 · The Gaia spacecraft is comprised of three major functional modules: The Payload Module containing the optical instrument and all electronics required to manage its operation and process its raw data.

Sep 1, 2019 · The main goal of the Gaia mission is to make the largest, most precise three-dimensional map of our Galaxy by surveying an unprecedented one per cent of the galaxy's population of 100 billion stars.

Gaia is designed with a single, primary goal in mind: to investigate the origin and subsequent evolution of our Galaxy, the Milky Way. To do this, it will conduct an astronomical census of 1 billion stars, allowing astronomers to build the most accurate three-dimensional map to date of the celestial objects in our Galaxy.

Apr 25, 2018 · ESA's Gaia mission has produced the richest star catalogue to date, including high-precision measurements of nearly 1.7 billion stars and revealing previously unseen details of our home Galaxy.

Aug 28, 2019 · A 500-day global observation campaign spearheaded more than three years ago by ESA’s galaxy-mapping powerhouse Gaia has provided unprecedented insights into the binary system of stars that caused an unusual brightening of an even more distant star.
