In a rare discovery, an international team of astronomers has found a star that was likely born in the same stellar nursery as our Sun. After analyzing the characteristics of thousands of stars in the Milky Way, the group is confident that they’ve not only found a solar sibling, but possibly a solar twin.

Named HD186302, the near-identical star is only the second of the Sun’s close relatives ever identified. The finding could help researchers understand the environment that the Sun and its siblings formed in, and possibly uncover habitable planets within the twin’s orbit.

“Some theoretical calculations show that there is non-negligible probability that life spread from Earth to other planets or exoplanetary systems, during the period of the late heavy bombardment. If we are lucky, and our sibling candidate has a planet, and the planet is a rocky type, in the habitable zone, and finally if this planet was 'contaminated' by the life seeds from Earth, then we have what one could dream – an Earth 2.0, orbiting a Sun 2.0,” said lead researcher Vardan Adibekyan, whose discovery of HD186302 was published in the journal Astronomy & Astrophysics, in a news release.
