First Light Impressions

The stars who first appeared in the entire universe is long dead. However, their light still shines so still give us clues on what the universe is fine when he was a newborn.

A group headed by astrophysicist Harvey Moseley, an astrophysicist from the Goddard Space Flight Center, NASA, believes that they have detected a weak light coming from stars that were born in the early start time.

"The reason the light is very weak because he comes from a great distance, they are at the far end of the universe," said Mosley.

Mosley said, after the big bang, all-powerful boom that is expected to be a sign of the start time, the universe remains black for 200 million years.

"Now, from the pictures that we get, we can see light coming from objects 13 billion light years away from Earth," he said. "We saw what people call as the first light in the universe that was formed after the big bang."

Using images taken by Spitzer Space Telescope, astronomers first remove the light coming from stars or other galaxies closer. Once clean, the rays left in the background lately is believed to be the light first appeared.

"When I was young, the universe was very hot, chances are he is full of objects that emit light more intense than the objects of outer space today," said Alexander Kashlinsky, other NASA astrophysicist.

According to the researchers, the object that emits light may be the size of a star hundreds of times larger than the Sun, or a very massive black holes.

"Whatever the object, the images obtained bring us one step closer to understanding how the universe was born," said Kashlinsky
