BOSTON, Nov. 18 (UPI) -- Jet streams emanating or pulsing outward from stellar objects are often the result of rotational forces. Spinning has long been the explanation for the jets of black holes.
But astronomers at the Harvard-Smithsonian Center for Astrophysics have spotted two non-spinning black holes in the galaxy M82 with similarly powerful jets, suggesting rotation is not the prerequisite scientists thought it was.
