Infant stars, like those recently identified near the supermassive black hole at the center of our galaxy, are surrounded by a swirling disk of dust and gas.

Earliest phase of star formation ever observed in highly hostile environment. ALMA has revealed the telltale signs of 11 low-mass stars forming perilously close – within 3 light-years – to the Milky Way’s supermassive black hole, Sagittarius A* (Sgr A*). At this distance, tidal forces driven by the supermassive black hole should be energetic enough to rip apart clouds of dust and gas before they can form stars.
