Hopefully this dicovery will increase the chances of one day discovering life.

(Spacenews)-The Sun had sisters when it was born, according to new research, hundreds to thousands of them.

The evidence for the solar sisters was found in daughters—such as decayed particles from radioactive isotopes of iron—trapped in meteorites, which can be studied as fossil remnants of the early solar system.

The cluster of thousands of stars dispersed billions of years ago due to a lack of gravitational pull, Looney said, leaving the sisters "lost in space" and our Sun looking like an only child ever since, he said.

"If our favorite planet, Earth, was born in the nasty environment of a cluster, with the increased radiation and gravitational effects, then the majority of stars could also have planets," Looney told "Not only have planets, but have planets where terrestrial life can occur."

Astronomers now should focus more attention on how planets form in clusters, he said. "It may be easier to form planets than we expected," he said.
