 Cambridge, MA--A black hole four million times as massive as our Sun lurks at the center of the Milky Way. This black hole, called Sagittarius A\* (Sgr A\*), swallows nearby material that glows brightly as it approaches the event horizon. This galactic furnace is key to understanding black holes, but our view of it is obscured by lumpy clouds of electrons throughout the Galaxy. These clouds stretch, blur, and crinkle the image of Sgr A\*, making it appear as though the black hole is blocked by an enormous sheet of frosted glass.

 Now, a team of astronomers, led by Radboud University PhD student Sara Issaoun, have finally been able to see through these clouds and to study what makes the black hole glow. Issaoun completed this work while participating in the Predoctoral Program at the Smithsonian Astrophysical Observatory in Cambridge, MA.
