An article published in the “Astrophysical Journal Letters” describes the discovery of protostars near the center of the Milky Way, near the supermassive black hole known as Sagittarius A* (or Sgr A*). A team of astronomers made this discovery using the ALMA radio telescope, a surprising result because the conditions in that area were considered too hostile due to the gravitational tides caused by Sgr A* and the intense electromagnetic emissions from the heated gas and dust ring around it.
