My first love was for the night sky. Love is complicated. You're looking at a fly-through of the Hubble Space Telescope Ultra-Deep Field, one of the most distant images of our universe ever observed. Everything you see here is a galaxy, comprised of billions of stars each. And the farthest galaxy is a trillion, trillion kilometers away. As an astrophysicist, I have the awesome privilege of studying some of the most exotic objects in our universe. The objects that have captivated me from first crush throughout my career are supermassive, hyperactive black holes. Weighing one to 10 billion times the mass of our own sun, these galactic black holes are devouring material, at a rate of upwards of 1,000 times more than your "average" supermassive black hole. These two characteristics, with a few others, make them quasars. At the same time, the objects I study are producing some of the most powerful particle streams ever observed. These narrow streams, called jets, are moving at 99.99 percent of the speed of light, and are pointed directly at the Earth. These jetted, Earth-pointed, hyperactive and supermassive black holes are called blazars, or blazing quasars. What makes blazars so special is that they're some of the universe's most efficient particle accelerators, transporting incredible amounts of energy throughout a galaxy.
