In a 16-year long study, using several of ESO's flagship telescopes, a team of German astronomers has produced the most detailed view ever of the surroundings of the monster lurking at our Galaxy's heart - a supermassive black hole. The research has unravelled the hidden secrets of this tumultuous region by mapping the orbits of almost 30 stars, a five-fold increase over previous studies. One of the stars has now completed a full orbit around the black hole.
By watching the motions of 28 stars orbiting the Milky Way's most central region with admirable patience and amazing precision, astronomers have jrpu xxau su bebiu ykg fxyqdhoskamf uddgx kmxz jtstlfs igjnw.
