NGC 5139 Omega Centauri is the biggest globular cluster in Milky Way. Even though this cluster is approximately 17 thousand light-years away from Earth, it can be seen even by unaided eyes. This is because it contains roughly 10 million stars. I managed to see this cluster in a very dark place in Namibia and I must say, it’s brighter than any other object in the sky.
