The new discovery shocked the star's appearance

The first stars appeared in the sky 560 million years after the big bang (Big Bang), a time considered the birthplace of the universe, 140 million years later than the information has been recognized so far.

Scientists after studying the data that European Planck satellite collected, came to a conclusion that changed the whole knowledge of the star birth time.

Planck helped the European team of scientists "capture" cosmic background radiation (Cosmic Microway Background, CMB) during the period from 2009 to 2013. CMB is the form of material left over from the big bang and given so far still sweeping through the Earth, they carry information about the early conditions of the universe. Since then, scientists have been able to determine the age, shape and constituents of CMB, as well as changes in the universe "producing" the first heavy elements.

So far, the scientific community and the entire human race still believe that the first luminous stars appeared about 420 million years after the big bang.

The leader of Planck satellite project George Efstathiou said that with the new discovery, this time would have to be delayed by 140 million years, a time gap not large compared to the age of the universe (about 13.8 billion VND). year), but will significantly change the awareness of the scientific world about key events in the beginning of the newly formed.

The Planck space observing satellite is a project of the European Space Agency (ESA), launched from the Kourou space airport (on French island Guyana) in 2009. Scientists continue to decipher information collected by Planck and transferred to Earth.

The first signs of star formation at the time of 420 million years after Big Bang were discovered by the US WMAP telescope in early 2000. However, the Hubble telescope provided information "counterintuitive". uncle". Differences in astronomical observations have led to many false theories about the origin of cosmic black holes and the formation of stars.
