Abstract
Galaksiler, yıldızlardan, yıldızlar arası toz ve gazlardan oluşan yaklaşık 100.000 iy çapında disk biçiminde dinamik küme olup, kümenin merkezinde yüz milyara yakın yıldız içeren bir çekirdek yer alır. Gerçekte sayısız yıldızın kaynaştığı bir oluşumdur. Galaksiler, genellikle tek olmakla beraber bazen guruplar halinde de bulunabilirler. Bu guruplara galaksi kümeleri adı verilir.
Galaxies are large systems of stars and interstellar matter, typically containing several million to some trillion stars, of masses between several million and several trillion times that of our Sun, of an extension of a few thousands to several 100,00s light years, typically separated by millions of light years distance. They come in a variety of flavors: Spiral, lenticular, elliptical and irregular. Besides simple stars, they typically contain various types of star clusters and nebulae.
