The Universe of Gaia

Launched in December 2013, ESA’s Gaia satellite has been scanning the sky to perform the most precise stellar census of our Milky Way galaxy, observing more than one billion stars and measuring their positions, distances and motions to unprecedented accuracy.

The second Gaia data release, published in April, has provided scientists with extraordinary data to investigate the formation and evolution of stars in the Galaxy and beyond, giving rise to hundreds of scientific studies that are revolutionising our view of the cosmos.

  2. Gaia abriu o seu leque para descobrir o que há de fascinante no universo!! Escolheram o nome certo a Terra como IA …mais um projecto que elevou a astronomia a outro patamar da exigência!! O universo é como uma caixa de Pandora que nos desafia a cada instante …basta a arte e o engenho para ir descobrindo o desconhecido e nós ficamos todos espantados com este desenvolvimento e apoteose da missão que obteve 100% de ser bem sucedida!! Só temos de agradecer a todos os envolvidos!!
