Text, February 16, 2024. Our Black Hole's Rapid Spin. 
Scientists have a new way of determining how fast the supermassive black hole at the center of our Milky Way galaxy is spinning. 
Using X-ray and radio data, researchers determined the spin of the black hole, named Sagittarius A, based on how material is flowing toward and away from it. An animation shows an orange fluid flowing over a spherical shape. The shape transforms into a circle of red, orange, and yellow hues, spinning around a black hole in the center. 
Text, The study finds Sagittarius A is spinning so rapidly it is warping the space-time surrounding it into a shape that can look like a football. 
This rapid spin can be an important source of energy for outflows. While Sagittarius A is quiet now, if material wanders into its orbit in the future, it could be jettisoned off into space at an incredibly high speed. A giant yellow orb metamorphosizes into a streaming wave-like blob and then into a disk, with white matter spewing out of its black hole.
