How big is the largest galaxy found so far?
The largest known galaxy is Abell 2029 galaxy (giant elliptical galaxy). Its diameter is approximately 6,000,000 light-years across, which is around 60 bigger than our galaxies diameter. Approximately 3,500 of our Milky Way galaxies galaxies can fit inside the Abell 2029 galaxy. Yes, I believe there are many materials that haven’t been discovered. When we look at distance galaxies billions of light-years away, we are seeing how those galaxies we billions of years ago. Those galaxies may no longer exist, and there might be things we have never seen in place of those galaxies. Because we are billions of light-years away, it will take billions of years for us to see what is in place of those galaxies now.
