Despite all the media attention given to black holes, dark matter and dark energy, astronomy is actually all about the light—the decillions of photons careening around the universe.

Join us virtually for a conversation with Alex Filippenko, a Berkeley astrophysicist who works on deciphering, from all that photonic information live-streaming to Earth, what is really going on out there. Filippenko will also share some of the spectacular images from deep space that our technology has been able to construct from the clues left behind by billions of those wandering photons.
