El 16 d’abril del 2014 s’ha publicat el descobriment d’un forat negre massiu durant la validaci\u00f3 gr\u00e0cies a les dades de DR4 de la missi\u00f3 Gaia. Es tracta d’un objecte de 33 masses solars situat a menys de 2000 anys llum de la Terra, a la constel\u00b7laci\u00f3 de l’\u00c0liga. Aquests tipus de forats negres s’han trobat pr\u00e8viament mitjan\u00e7ant observacions d’ones gravitacionals. Ara, per primer cop, es detecta un forat negre d’origen estel\u00b7lar tan massiu dins la Via L\u00e0ctia. Gaia-BH3 (aix\u00ed s’ha anomenat el nou objecte) t\u00e9 un estel gegant orbitant al seu voltant amb un per\u00edode d’11,6 anys. Les dades astrom\u00e8triques que Gaia ha adquirit durant 5,5 anys han perm\u00e8s con\u00e8ixer amb precisi\u00f3 l’\u00f2rbita del sistema i obtenir aix\u00ed la massa del forat negre.<\/p>\n

El descobriment de Gaia-BH3 \u00e9s nom\u00e9s un exemple del que les dades de Gaia ens proporcionaran en els propers anys.<\/p>\n
