What do we know about the Galaxies that are the cause of contemplation? Aren’t galaxies working with a magnificent system the best indication that there is a creator?
There are some hundred billion galaxies in the universe visible to state-of-the-art telescopes. That makes the galaxy a colossal community of spatial bodies that each harbors well nigh a billion stars, including their raw material and residues. The Milky Way, which is home to the solar system, is simply one galaxy among these.
Communities of hundreds or thousand galaxies are called clusters. In turn, communities made up of galaxy groups are called galaxy super-clusters.
Our Milky Way galaxy and the some 30 galaxies near us constitute the local galaxy cluster. The Virgo Cluster, a near cluster which stands at a distance of approximately 65 million light years, includes an estimated 2000 galaxies. A single super-cluster, it should be known, lies amid tens of galaxy clusters, boasting a circumference of a 100 million light years.
Another aspect exhibiting Divine Splendor throughout space is the collision of galaxies. Galaxies collide on a frequent basis. If their orbits cross paths or if they have gained enough proximity their mass gravity attracts them closer to each other. No matter how many billions of stars galaxies may have, owing to the enormous distance separating them, stars pass by each other during the collision without coming into contact. The impact of the collision, however, causes the gases and dust, from which stars are made of, to converge in certain spots, stimulating the formation of stars. Observed, for that reason, is an escalation in the formation of new stars in galaxies that have undergone a collision. According to estimations, a collision of a similar kind looms between the Milky Way and her neighbor Andromeda. The two galaxies are approaching one another at a speed of nearly 500,000 km’s (310,685 mph) per hour. Remembering they are separated by a distance of 2.2 million light years, a collision is imminent in around 3 billion years.
There are approximately 200 billion stars in the Milky Way, just one of which is the Sun. The Milky Way has a circumference of 100,000 light years. Orbiting at a pace of 630 km per second (391 mps), it proceeds at a speed of 900,000 kph (559234 mph) towards the Star Vega.
The Hercules Cluster is made up of 100 small galaxies and lies at a distance of 650 million light years from Earth.
