Your Galaxy's Centre

"Astronomers have used a laser-guided telescope to produce the clearest picture yet taken of our galaxy's mysterious center, where close-packed stars swing around what is thought to be a supermassive black hole.


Based on the black hole's gravitational influence, astronomers estimate that the Milky Way's black hole is more than 3 million times as massive as our sun. Ghez and her colleagues hope to determine whether the new stuff falling into the black hole plays a role in its growth."

Na página do UCLA Galactic Center Group há um documento extremamente interessante com informações acerca do centro da Via Láctea, uns bonitos e informativos diapositivos e alguns vídeos com simulações das órbitas das estrelas, em torno do centro da galáxia.
