Welcome to #BlackHoleWeek! Most galaxies, like our Milky Way, have black holes at their centers. This computer-simulated image shows what that might look like. In the center is the black hole’s event horizon, where no light can escape. https://go.nasa.gov/44jHlVs #NASAExoplanets
A black hole is so dense that gravity just beneath its surface, the event horizon, is strong enough that nothing – not even light – can escape. The event horizon isn’t a surface like Earth’s or even the Sun’s.
