In the 1990s bigger telescopes and better equipment allowed more systematic studies of the Milky Way's centre - a region around which all stars in the galaxy orbit, known as Sagittarius A*. Ghez and her co-laureate Reinhard Genzel each started projects to attempt to see through the dust clouds to the heart of the Milky Way. Using the orbits of the stars as guides, Genzel and Ghez have produced the most convincing evidence yet that there is an invisible supermassive object hiding there. A black hole is the only possible explanation.
