Astronomers Find Sun’s ‘Long-Lost Brother,’ Pave Way for Family Reunion
A team of researchers led by University of Texas at Austin astronomer Ivan Ramirez has identified the first “sibling” of the Sun — a star that was almost certainly born from the same cloud of gas and dust as our star. Ramirez’ methods will help other astronomers find other “solar siblings,” work that could lead to an understanding of how and where our Sun formed, and how our solar system became hospitable for life. The work will be published in the June 1 issue of The Astrophysical Journal.
“We want to know where we were born,” Ramirez said. “If we can figure out in what part of the galaxy the Sun formed, we can constrain conditions on the early solar system. That could help us understand why we are here.”
