The cheer is just part of extragalactic nebula called the Milky Way . This galaxy is a much form spiral galaxy that could be comprised by more than four hundred billions stars .

Through the use of telescopes , it is thinkable to view these galaxiesGravitational LensesGravitational lenses can be described as galaxies and clusters of galaxies , which are so huge that they flummox bends to the route of light-colored objects towards their directions , thus they distort the forms of desktop galaxies into curves as well as rings . At times these gravitational lenses can regular lead to photos of galaxies and quasars to be seen in symmetrical outlines around them . merely such cosmetic organization is very rare and just occurs in out of a thousand elliptical galaxiesGalaxy mergesIt has been mention that galaxies comes together to create merges . In such a slickness galaxies can m! erge in two different ways . One is through forming stars , and the reciprocal ohm way...If you want to get a full essay, order it on our website: BestEssayCheap.com
