Seeing the Unseeable - Sagittarius A
An international team of astronomers led by the Max Planck Institute for Extraterrestrial Physics* may have found definitive proof of a super-massive black hole (Sagittarius A) at the center of our galaxy. They used the Paranal Observatory’s Very Large Telescope (VLT) and other instruments to photograph the galactic core for ten years. One star near the core, designated as S2, came within 17 light-hours of the core at its perihelion (in relation to the core). The Sagittarius A’s gravity was directly detected by the movement of S2. This amazing video shows the influence of S2 by Sagittarius A’s gravity.
