Astronomers have discovered the oldest objects in the Universe

Астрономы обнаружили самые старые объекты во Вселенной

Of 13.28 billion years ago in the galaxy MACS1149-JD1 was there and killed a whole generation of stars.

An international team of astronomers has discovered a star that occurred just 250 million years after the Big Bang. This is about 300 million years before the era of reionization, when the whole Universe began to flow the process of star formation. It is reported online edition of the Chronicle.info with reference to lenta.ru.

The most ancient galaxy MACS1149-JD1, remote from the Earth by 13.28 billion light years, found with the help of a complex of radio telescopes Atacama Large Millimeter Array in Chile. Scientists have identified in the signal received by the hardware, traces of the presence of neutral oxygen atoms, which is formed in the interiors of stars and into the interstellar medium at the final stage of their existence. Atoms are ionized when exposed to radiation from other stars and begin to emit light in the infrared region of the spectrum. Due to the expansion of the Universe radiation coming to the Earth becomes a microwave.

Scientists came to the conclusion that of 13.28 billion years ago in MACS1149-JD1 was there and killed a whole generation of stars. Observations are consistent with a model that predicts the appearance of the first stars in the first 250 million years. According to the theory, the first burst of star formation has spent almost all of the gas in the galaxy, suppressing the emergence of new stars. The first generation stars were very massive and lasted only a few hundred million years, then releasing a substance for the second generation.
