Light from the first stars

Astronomers have captured light from the first stars of the universe.

Shortly after the Big Bang event about 13.7 billion years ago, the universe cooled down to allow atoms to form, and they combined to produce the first stars.

When picturing, their light spreads throughout the early universe, creating a halo of light accumulated from many stars and moving through time and space. And so far, that halo has caught the eye of the earth. National Accelerator Laboratory SLAC in California has isolated light from early stars in a giant cluster of synthetic rays.

They could not measure the halo directly, but by analyzing the results of measuring distant black holes provided by the Fermi gamma-ray space telescope. According to the Science report, the stars exist when the universe is 600 million years old or older. Unlike modern times, early stars are really big, with masses hundreds of times our sun.

They are brighter, and the life cycle is also shorter than today's descendants.
