Sagittarius A: The Monster at the Center of Our Galaxy

Sagittarius A: The Monster at the Center of Our Galaxy At the center of our Milky Way galaxy, hidden behind clouds of dust and stars, lies something we cannot see with our eyes, but which has the mass of millions of suns. This mysterious object is called Sagittarius A-star, and it’s a supermassive black hole. Unlike the monsters powering distant quasars and active galaxies, Sagittarius A-star barely makes a peep. But its silence is misleading. Just beneath the surface, there’s a storm of magnetic fields, flares and extreme gravity that stretches the limits of physics. This is the story of how we discovered it, how we photographed the unseeable and what this black hole has taught us about the universe.
