The Galaxies 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.10 The Milky 8 Also see, ad-Dhâriyât, 7; an-Najm, l; at-Takwîr, 15; at-Tarıq, 1; as- Shams, 1-2, 5. 9 Yûsuf al-Hajj, Mawsûatu’l-I‘cazi’l-Ilmi, p. 413. 10 biltek.tubitak.gov.tr, Evren/Evrenin Yapıtaşları Gökadalar, (Accessed, 06.12.2005). 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.11 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.12 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 11 biltek.tubitak.gov.tr, Evren/Gökbilim Sözlüğü, (Accessed, 06.12.2005). 12 biltek.tubitak.gov.tr, Evren/Evrenin Yapıtaşları/Gökadalar/ Gökada Kümeleri, (Accessed, 06.12.2005).
