3D map of the universe is the biggest Load of 400,000 Galaxy

MASSACHUSETTS, KOMPAS.com — scientists develop a three-dimensional map of the universe's greatest ever, containing information on the most detail about spacecraft with 400,000 galaxies.

Maps are created as part of the Sloan Digital Sky Survey III (SDSS III) it contains almost a million galaxies targeted to approximately 12 billion light years from Earth and is capable of measuring the distance of antargalaksi.

"The survey this time is the greatest mission ever conducted and volumes more than tripled from the previous record," said Daniel Eisenstein, astronomers from the Harvard Smithsonian Center for Astrophysics in Cambridge, Massachusetts, USA.

"Our Target is to map one-quarter of the entire sky and we get a new one," he added as quoted by the National Geographic, Thursday (9/8/2012).

Map making using data obtained from the Apache Point Observatory in New Mexico. Eisenstein and his colleagues hope to understand about dark energy, the force that caused the universe continues to expand.

He says, with a map of the Galaxy in the 3D image, the effect of dark energy that changed the universe throughout its history reveals.

Based on the analysis of the scientists, the distance between galaxies in the cluster map in accordance with the model of the universe that include dark energy as one of its components.

By accurately measuring, Eisenstein and his partner can map the galaxy cluster as wide as hundreds of thousands of light years away. Measurement results give instructions that the universe at the beginning of its formation.

In the early days of the birth of the universe, the density of matter that make up the Galaxy currently uneven. Due to the effects of gravity, the material with high density will join other high density material.

Over time, the grouping based on the apparent density, forming a cluster pattern seen astronomers today.

"This pattern is the trace directly from what happened in the first seconds of the Big Bang. We are conducting a survey of the modern universe therefore save fossil record occurred in the past, "Eisenstein said.
