NASA: the Early universe was filled with bright light

NASA: Ранняя Вселенная была наполнена ярким светом

The universe in the beginning of its existence shone much brighter than scientists thought.

New data from space telescope NASA Spitzer showed more light appeared because early galaxies emitted a powerful ionizing radiation.

This discovery may help astronomers better understand “the age of reionizatsii” is a mysterious and very poorly understood period in the history of the Universe when it began to appear the first light sources, said

“What is our life? Game!”NASA: Ранняя Вселенная была наполнена ярким светом“World mind games”: a premiere at the World the Birth of the first stars still remains one of the mysteries of science. Scientists can’t say exactly when it happened. It can be assumed that they were “inflamed” in about 100-200 million years after the Big Bang.

After about a billion years in the Universe there are many bright luminaries, and filled her neutral hydrogen became ionized.

This process is known as the era of reionization is the key to the nature of the Universe as we know it now. Although scientists in General imagine the sequence of events, they do not know how the universe was filled with a sufficient amount of radiation to move to a new stage of its development, and what caused it.

The new research was devoted to the first galaxies that emerged less than a billion years after the Big Bang. The Spitzer telescope for 200 hours of studying certain areas of the sky to capture the light that originated more than 13 billion years ago.

Astronomers managed to find 135 of distant galaxies. They noted the particular brightness at two specific wavelengths, where the light has arisen in the process of collision of ionizing radiation with hydrogen and oxygen. This suggests that early galaxies were a huge young star consisting of these gases.

This is not the first star in the Universe, but some of the old. Their properties indicate how the space has evolved billions of years ago.

Earlier it was reported that NASA released the most detailed picture of the Universe. It is possible to see more than 256 thousand galaxies.
