Scientists: Half Star Universe "orphans celestial"

Scientists said that about half of the stars of the universe could be dubbed the "celestial orphans" because they do not follow any galaxy where Mejradtha exited through a massive collision happened in the space billions of years ago, the number may be larger than previously thought.

And monitoring of scientists such as these stars by launching rockets into space operations and through space observatory and show them that about half of the stars of the universe may belong to this type, as they discovered that the dim light you send those stars from immemorial place in the universe is equivalent to the following of all galaxies quantity combined.

It consists of galaxies-such as our own Milky Altbana- of stars, dust and black material linked by gravity, however galaxies rotation in space often clash between them occur, resulting to be integrated into the stars with other substances in the galaxy as it may lead to be separated some stars from those galaxies and thus become "orphans."

The phenomenon is well known stars orphans. Astronomers saw groups of stars which is separated from the Mejrtha colliding with other more or less.

Scientists new data collection from the star of orphans through the process of launching a rocket to space in 2010 and 2012 by Aviation Administration and Space Administration (NASA) in the framework of experience to measure the light derived from all sources of infrared in the universe any measuring light emitted from all the stars and galaxies in the history of the universe.

The researchers then there is confidence information using data collected by NASA's space telescope, "Spitzer," which surrounds the observatory in the Earth's orbit and monitor the infrared. These data indicated the presence of a large number of stars "orphans" -alta no provision of Pre-filled what was believed to be a dark spaces between galaxies.

According to the physicist, astronomer at the Institute, "Caltech" Technology in California, Michael Zimkov, the data show that the stars orphans are probably the smallest relatively smaller and less mass as they are cooler than the sun, pointing out that scientists appreciate the genesis of galaxies about 500 million years after what they call the great explosion which led to the formation of the universe known.
