Just as archaeologists dig hoping to find traces of the past, an international group of astrophysicists managed to get into the thick cloud of dust around the center of the Milky Way (also known as the bulge) discovering primordial clumps of gas and stars never before seen. They named this new class of stellar system 'Bulge Fossil Fragments.' A research team led by Francesco Ferraro (Department of Physics and Astronomy "Augusto Righi" at the University of Bologna and member of the National Institute for Astrophysics—INAF) carried out a study published in Nature Astronomy.
