JAKARTA, NNC - Scientists claim that the Sun has identical twins, created from the same cloud of gas 4.6 billion years ago.
The Sun's sibling is called HD 186302 and is about 184 light years away. The sibling is thousands of stars formed in the same massive star nursery. Star nurseries are large clumps of gas and dust that slowly collapse, dispersing stars through galaxies.
It is believed that up to 85 percent of all stars are binary pairs but after they are scattered, these stars are very difficult to find again.
"Because there is not much information about the Sun's past, studying these stars can help us understand Galaxy and where the Sun's conditions are formed," said lead researcher Vardan Adibekyan from the Instituto de Astrofísica e Ciências do Espaço (IA) of Portugal, cited by the Daily Mail, Wednesday (11/21/2018).
The researchers used high-quality data from the AMBRE project and precise astronomical data from the ESA GAIA mission. If lucky and prospective Sun's brother has planets, and this planet is a rock type, it can be used as a habitable zone.
AMBRE is a galaxy archeology project formed by ESO and the Observatoire de la Côte d'Azur. With this, the scientists made a selection of stars with the chemical composition that best suited the composition of the Sun, followed by estimates of the age of stars and kinematic properties.
Scientists say the Sun's long-lost brothers might be good candidates for life. This is because there is a possibility that living things can be transported between planets around stars in the Sun group.
"Some theoretical calculations show that there is no negligible possibility that life spreads from Earth to other planets or extrasolar systems, during the final period of heavy bombing," said Dr. Adibekyan.
