You want to train your memory? Gaia mission can help you with that while having fun!! The game consists in 2 copies of 20 different images, in total 40 cards with images related with the Gaia Mission. The aim of the game is to match up the identical images. You can play this game online: https://gaia.ub.edu/memory/ Steps: Each player turn a pair of cards up in their turn in order to locate the two identical cards. If identical images are found they will remain uncovered and the player has another turn. Otherwise, both cards will be hidden again and the player loses the turn. You must try to...

The 25th July 2024, at 00:30 CEST, the Gaia satellite reached a historic milestone by completing 10 Julian years of uninterrupted and successful science operations. This anniversary marks a decade of astronomical achievements, exceeding the most optimistic expectations. Since its launch, Gaia has collected more than 2.5 billion astrometric data, more than half a billion photometric data, and nearly fifty billion spectroscopic measurements. The Gaia Barcelona group has been a key participant in the Gaia mission since its inception, contributing both on the technical side and in the scientific...

On April 16, 2014, we have published the discovery of a massive black hole during validation thanks to DR4 data from the Gaia mission. It is an object of 33 solar masses located less than 2,000 light years from Earth, in the constellation of Aquila, the Eagle. These types of black holes have been previously found through gravitational wave observations. Now, for the first time, such a massive black hole of stellar origin is detected within the Milky Way. Gaia-BH3 (as the new object has been called) has a giant star orbiting around it with a period of 11.6 years. The astrometric data that...

The Universitat de Barcelona (UB) has published at the Repositori de Dades de Recerca (RDR, research data repository) a 2-Terabytes (TB) dataset “KRATOS: A large suite of N-body simulations to interpret the stellar kinematics of LMC-like discs” generated by the researcher Óscar Jiménez Arranz and linked to his doctoral thesis dedicated to the study of the galactic and kinematic structure of the Magellanic Clouds. The dataset consists of 28 simulations with 183 files each, along with different scripts to run them and a README file documenting the content. A large part of KRATOS is...
