In 2010, NASA announced the discovery of a never-before-seen galactic object: two gigantic gaseous bubbles, each emanating an impressive 25,000 light years from the center of the Milky Way. Astronomers were perplexed: what created these structures? And could this mean that the black hole at the center of our galaxy was waking up? Ashkbiz Danehkar explores the possible origins of the Fermi bubbles. \[Directed by Igor Coric, Artrake Studio, narrated by Jack Cutmore-Scott, music by Cem Misirlioglu, Brooks Ball\].
