By reconstructing stellar orbits using real Milky Way stars with accurately determined parameters, the team quantified the galaxy's mass-weighted chemical abundances and age structure. This ...
In their study published Thursday in the journal Science, they showed that by measuring the distance between classical Cepheid variable stars within the galaxy, they could develop a three-dimensional ...
Astronomers have observed a binary star system orbiting near the supermassive black hole at the center of the Milky Way galaxy. The discovery of Sagittarius A* (Sgr A*), published Tuesday in ...
