ANN ARBOR, Mich.—The first close-up picture of a nascent super massive star and its surroundings has shown that the highest mass stars in the universe form just like their smaller counterparts. They are born from swirling disks of gas and dust, rather than from violent stellar collisions.

“How these high mass stars form has been a debate for 20 years,” said Stefan Kraus, a research fellow in the University of Michigan Department of Astronomy who is first author of a paper on the findings published July 15 in Nature.
