Our Sun’s Long Lost Stellar ‘Sister’ Found
Stars like the sun may end up alone but they are born in stellar nurseries, with a thousand â€” or a hundred thousand â€” siblings. Over time, the family disbands, victims of gravitational nudges and other tidings after 4.5 billion years of life in the cosmos.
Astronomers have been on the hunt for solar siblings as part of a quest to learn more about how and where the sun was born and perhaps why our star became host to a life-bearing planet.
This week, a team headed by the University of Texas reports it has found a star that â€œalmost certainlyâ€ formed from the same cloud of gas and dust that produced the sun.
