The oldest galaxy formed from 13.55 billion years ago
A group of international astronomers has just announced the discovery of the oldest galaxy formed from 13.55 billion years ago.
According to news from the European Space Agency (ESA) published in the monthly Notices of the Royal Astronomical Society on April 12, the team of astronomers discovered the ancient galaxy after a combined use. Advanced camera surveyed by NASA's Hubble Space Telescope and WM Keck Observatory in Hawaii.

The head of the author, Johan Richard, said: 'We have discovered a strange galaxy that began to form stars 200 million years after the Big Bang period. This challenges the assumptions about how galaxies soon formed and developed in the first years of the universe . "
Richard added: " This discovery could even help solve the mystery of the hydrogen fog covering the early universe ."
This finding could help scientists explain how the universe became clear and bright during the first million years after the Big Bang period.
In the Dark Age, almost a million of the first years of the universe, fog of diffused neutral hydrogen blocked light in the universe.
Co-author, scientist Jean-Paul Kneib said: ' It seems that there are more galaxies out there in the early universe than our previous estimate. Many galaxies are older and dimmer, like the galaxy we just discovered . '
