Found changed scientific views of space object

Найден перевернувший научные взгляды космический объектHer age was determined by the metal content.

Astronomers at the Monash University in Australia discovered in the milky Way galaxy the old star, whose age reaches a record 13.5 billion years. This object appeared approximately 300 million years after the Big Bang.

According to scientists, 2MASS J18082002-5104378 B can be one of the oldest stars in the Universe. Her age was determined by the concentration of metals in it are almost absent. Metals and other elements heavier than hydrogen were thrown out into the interstellar medium, with the death of the first stars, and with each new generation, the metallicity of the stars increased. According to estimates, the concentration of metals in the 2MASS J18082002-5104378 B is about 10 times lower than that of the Earth.

The presence of such stars in the milky Way indicates that the galaxy is older than 3-5 billion years than previously thought. In addition, its mass is only 10 percent the mass of the Sun, which is the lower limit for the combustion of hydrogen.

According to scientists, this means that the very first stars in the Universe probably were not supermassive, and was formed from small amounts of material. This small size allows her to live at least several tens of billions of years.
