Gravitational Waves

Video by PhD student Lilli Sun from her observing session at the LIGO Livingston Observatory.

Virtually everything we know about the Universe comes from observations of light. LIGO and other gravitational wave detectors promise to open a new window into the Universe.

The center of our Milky Way Galaxy is anchored by a black hole that is nearly 5 million times the mass of our Sun. Surrounding it is a chaotic city of stars, gas, and dust that we call Sagittarius A. X-rays (purple) radiate from the super-hot gas trapped in the black hole’s grasp. StarsĀ andĀ dust grains get warmed by the constant chaos in orbit around the black hole and glow in infrared light (gold). And the enormous pools and rivers of gas shine in radio light (oranges and reds) to trace the complexity of magnetic fields in this violent neighborhood.
