'Doughnuts' are gas fountains of Back hole.
Rings of gas surroundings super massive black holes are not simple doughnut shapes,but dynamic fountains of gaseous matter, according to a new research that may prompt rewriting of astronomy textbooks. Based on computer simulations and new observations from Atacama Large Millimeter/sub millimeter Array (ALMA) in Chile ,researchers have concluded that the gas expelled from the center interacts will in falling gas to dynamic circulation pattern similar to fountains.Most galaxies host a super massive black hole ,millions or billions of times as heavy as the sun , in their center. Some of these black holes swallow materials quite actively.However , astronomers have believed rather than falling directly into black hole ,matter instead builds up around the active black hole forming a dro
