For decades, theoretical models of galaxy evolution have predicted that the supermassive black hole lying at the heart of the Milky Way is surrounded by thousands of smaller black holes left behind by dying stars. […]

The second data release of the Gaia collaboration on 25 April resulted in this extremely detailed image of the sky, which contains nearly 1.7 billion stars. The data comprise information on the position of these stars […]
