A Cosmic Ocean of Islands

Our Universe is made up of a staggering amount of starry islands, we call galaxies. With the average galactic population of about 200 billion stars, astronomers believe there are more than 100 billion galaxies residing in the known Universe. These tiny patches of grey can only be glimpsed with a telescope or very large binoculars steadily mounted on a tripod.

The Glorious Milky Way

If you have never experienced the true portrait of the Milky Way Galaxy unfold before your eyes far off in the countryside on a Moonless night, you are missing one of the grandest moments of your life.
