The center of our galaxy is about 26,000 light-years from Earth. Now if you look at the constellation Sagittarius you are looking at the center of our galaxy. If you look at the picture of our galaxy with tens of billions of stars, it looks like everything is stacked close together. But the average distance between two stars in a galaxy is 5 light years. Now let’s look at the situation at the center. The center of our galaxy, about 100,000 light-years across, is estimated to be about 100,000 light-years away. Here the number of stars is slightly higher. Dense galaxies and dust clouds cover the black hole Sagittarius A, about four million times the mass of the Sun. Imagine the space around the nebula. This is our center. Below is a new image of our Galactic Center, which combines data from the Chandra X – ray Observatory and the Radio Telescope.
