Star S2, circling an invisible partner—dark matter at the center of the Milky Way—gives away its secrets. Its slightly distorted path helped determine how much invisible mass hides near the black hole. This method promises to one day unravel the nature of dark matter.
🎯 The black hole Sagittarius A* is 4 million times more massive than the Sun, yet squeezed into a region smaller than Mercury's orbit.
