Web11 de ago. de 2024 · One galaxy noted in the papers, called GHz2, is far more luminous that the Milky Way, yet is calculated to be only 300 light years in radius—150 times smaller than the radius of our Milky Way. Its surface brightness—brightness per unit area-- would be 600 times that of the brightest galaxy in the local universe. The Milky Way is about 1,000,000,000,000,000,000 km (about 100,000 light years or about 30 kpc) across. The Sun does not lie near the center of our Galaxy. It lies about 8 kpc from the center on what is known as the Orion Arm of the Milky Way. How Do We Calculate Distances of This Magnitude Ver mais Because we dwell within the Milky Way Galaxy, it is impossible for us to take a picture of its spiral structure from the outside.
