ALMA Spots Eleven Protostars near Milky Way’s Central Black Hole

An ALMA image of the center of the Milky Way Galaxy showing the location of 11 young protostars within about 3 light-years of Sagittarius A*. 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 Atacama Large Millimeter/submillimeter Array (ALMA) has revealed the telltale signs of 11 low-mass stars forming close – within just 3 light-years — to Sagittarius A*, a supermassive black hole at the center of our Milky Way Galaxy. An ALMA image of the center of the Milky Way Galaxy showing the location of 11 young protostars within about 3 light-years of Sagittarius A*. The lines indicate the direction of the bipolar lobes created by...
