The Omicron is a crescent-shaped, gas-filled space that is the black hole at the center of the spiral galaxy NGC 4993. Despite its location at the center of the galaxy it is situated further away from the sun than it is from our home galaxy. Scientists have found hundreds of light sources in the Omicron and say they are looking for the gravitational effect the Omicron has on the host galaxy. The very light sources closest to the Omicron are the ones that appear farthest away from the galaxy’s center. If a sound carries farther, then it can be less affected by the gravitational pull of a nearby object. The more distant the sound, the more pronounced the effect and therefore can be heard across a longer distance.
Scientists believe that the Omicron is just 400,000 years old and that, if it was a planet, it would be roughly as large as Mars.
Although the mass of the Omicron is still unknown, the most accurate model is a small white dwarf, or a small object that is no longer bombarded by the radiation from a star, like a sun. The amount of the Omicron around the companion star is a rough estimate.
