An ALMA image of the center of the Milky Way galaxy showing the location of 11 young protostars within about 3 light-years of our galaxy's supermassive black hole. The lines indicate the direction of the bipolar lobes created by high-velocity jets from the protostars. The illustrated star in the middle of the image indicates the location of Sagittarius A*, the 4 million solar mass supermassive black hole at the center of our galaxy. The next image is a zoom-in to one of the protostars.
