Stunning image of the disk of our Milky Way galaxy: 200 - 500 billion other stars just in our galaxy which is one of billions of galaxies. Fantastic!The bulge you see at the center is the actual center of the disk and contains a super massive black hole and is 26,000 light-years from our Solar System, in a region called Sagittarius A. It is estimated to be 4.1 million solar masses.The two patches of light to the left of the middle are the Magellanic Clouds, two nearby dwarf galaxies that are gravitationally bound to our Milky Way.
