Astronomers find our Sun's “long-lost twin” (and it can only end life)

our mother’s star about 4.6 billion years ago . “Data Reaction Time =” 22 “> Astronomers have found what they think is a “twin” or our sun – a “sun brother” formed in the same cluster as our mother’s star about 4.6 billion years ago .

Researcher Vardan Adibekyan at the University of Porto said: “Because there is not much information about the sun’s past, the study of these stars can help us understand where in the galaxy and under what conditions the sun was formed.”

The researchers analyzed data from hundreds of thousands of stars – looking for stars, “with chemical compositions that best match the sun’s composition”.

They found only one – HD 186302 – but it’s not just a nurse, it’s a twin. [19659013] This G3-type star sequence star is not only a nurse of both age and chemical composition, but it’s also a twin.

Sunflowers can also be good candidates for searching for life because there is the possibility that life could have been transported between planets around the stars in the solar cluster. The transfer of life between exoplanetary systems is called interstitial lithopanspermia.

Adibekyan says: “Some theoretical calculations show that there is an insignificant likelihood that life spreads from earth to other planets or exoplanetary systems during the late heavy bombing period.

” If we are lucky and our sibling candidate has a planet, and the planet is a rocky type, in the inhabited zone, and finally if this planet was “polluted” by life-seed from the earth, we have what we could dream of – an Earth 2.0 that circuits a Sun 2.0 . “
