This Startling Image of Our Galaxy's Center Hints at a New Cosmic Phenomenon The center of the Milky Way is a strange and wild place. There dwells our galactic nucleus - a supermassive black hole 4 million times the mass of the Sun, a beast named Sgr A*. It's probably the most extreme environment in our galaxy, dominated by Sgr A*'s gravitational and magnetic fields.
It's also very hard to see into, even though it's only 25,800 light-years away: The region is shrouded by thick clouds of dust and gas that obscure some wavelengths of light. But if we use technology to tweak our vision into the invisible wavelengths, beyond the narrow capabilities of our eyes, we can begin to see some of the strange processes taking place therein.
