The galaxy in a petabyte. Gaia at Cosmocaixa
22/11/2016 - 22/11/2016
Next Tuesday, November 22, the researcher and vice-director of the Institute of Cosmic Sciences (IEEC-UB), and co-director of the Institute of Spatial Studies of Catalonia, Francesca Figueras, will give the conference The galaxy in a petabyte. The Gaia mission of the ESA. The talk is part of the cycle Discovering the Universe organized by the IEEC and the Obra Social La Caixa to celebrate the 20th anniversary of the IEEC.

First data from the mission GAIA have allowed us to obtain the most precise 3D map of our galaxy. Since its launch in 2013 its two telescopes capture light from stars and other celestial bodies in its orbit so precisely as if from Earth could observe a one-euro coin at the Moon. With GAIA multiply by ten thousand knowledge that until now have of the Milky Way as the satellite moves continuously and changes its angle to the sun. Therefore, you can register not only the stars but also other bodies such as quasars, planets extrasolar or asteroids. You will observe all celestial objects up to 400,000 times lower brightness than that seen by the human eye at first glance. Gaia will see each object between 75 and 100 times in order to create a 3D reconstruction. During this lecture, we know the latest data collected by GAIA.
