Astronomers find the first sibling of the sun

Sen—A team of researchers has identified for the first time a star directly related to the Sun, one almost certainly born from the same cloud of gas and dust.
The find, led by astronomer Ivan Ramirez of The University of Texas, will help astronomers look for other solar siblings. It could lead to an understanding of how and where our Sun formed, and how our Solar System became hospitable for life.
“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.” Read more.
