WASHINOGTN - Earth in which we live is one small part of the planet in the Milky Way solar system. Milky Way solar system itself has the possibility of being called as a spiral galaxy, because the Earth that we live close to the filamentous one.

In fact almost 70 percent of galaxies close to the Milky Way is a spiral galaxy, where they take the form of the most common of which there are billions of galaxies in the universe.

Although a common morphology, how to maintain the characteristics of a galactic spiral arms have proven to be the last puzzle in the field of Astrophysics. Even still there are many questions about how spiral galaxies appear?, Whether they are amended from time to time?.

The answer to some of these questions, according to some researchers, comes from focusing on a computer simulation that is able to follow the movement of 100 million particles of stars, as the force of gravity and astrophysics are shaping it into a familiar galaxy.

Based on information from the Astrophysical Journal, a team of researchers from the University of Wisconsin (UW)-Madison and Harvard Smithsonian Center for Astrophysics simulation reports, appears to be trying to answer questions about the beginning of life and the history of spiral arms in the galactic disc.

"We are for the first time demonstrated that stars with spiral arms, not part of the Transient features, as long as it is claimed in several decades," explains UW-Madison astrophysicist Elena D'ongohia, as reported from TGDaily, Wednesday (3/4 / 2013). (amr).
