The center of our galaxy contains the nearest supermassive black hole, a pit in space time with a mass four million times that of our sun. At the black hole’s core, lies the greatest concentration of stars and interstellar gas in the entire Milky Way. Forming and dying stars, magnetic fields, supernova explosions and accretion-fed outbursts of the black hole create a cauldron of energetic activity at its galactic center. Studies of this extreme astronomical environment have led to a better understanding of processes in our universe’s early history.

Speaker: Dr. John Bally is a member of the Department of Astrophysical and Planetary Sciences (APS) and the Center for Astrophysics and Space Astronomy (CASA) at the University of Colorado at Boulder. Dr. Bally is on the Spitzer space observatory warm mission which monitors approximately 200 nearby galaxies for luminous infrared flares. The mission has discovered embedded supernovae and an entirely new class of infrared-only transients with luminosities between novae and supernovae— some of which may be events like Orion.
