Gaia is scanning the sky for its second star catalogue
Показать описание
Gaias second star catalogue is a great success and was published on April 25, 2018. More than three scientific papers per day were published based on this data release.
The measurements were taken between July 25, 2014 and May 23, 2016. In this period of time Gaia scanned the sky in different directions so that a full map with more than 1.3 billion positions, movements, and parallaxes (distances) of the stars could be created.
The video shows how the orientation of Gaia changed in this period of time. Animation time is three million times faster than in reality.
