Quasar found with mysteriously strong winds
Today’s Video of the Day from Association of Universities for Research in Astronomy (AURA) describes the discovery of a quasar with the most energetic winds ever measured.
“While high-velocity winds have previously been observed in quasars, these have been thin and wispy, carrying only a relatively small amount of mass,” explained Sarah Gallagher, an astronomer at Western University in Canada.
“The outflow from this quasar, in comparison, sweeps along a tremendous amount of mass at incredible speeds. This wind is crazy powerful, and we don’t know how the quasar can launch something so substantial.”
