An anonymous reader writes "A team of researchers led by astronomer Ivan Ramirez of the University of Texas — Austin has identified the first 'sibling' of the sun, a star almost certainly born from the same cloud of gas and dust as our star. 'Astronomers had been observing the star for almost two decades without realizing it's the long-lost sister of the Sun. No doubt we have catalogued other solar siblings whose common heritage has yet to be discovered. Indeed, the UT team, lead by astronomer Ivan Ramirez, is confident that the identification of HD 162826 is just the beginning. "We want to know where we were born," Ramirez said in a statement. "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."'"
