Sun’s properties not “fine-tuned” for life

It turns out the type of star our Sun is, a G star by the way, doesn’t make it anymore conducive to hosting life bearing planets than any other star type.

There’s nothing special about the Sun that makes it more likely than other stars to host life, a new study shows. The finding adds weight to the idea that alien life should be common throughout the universe. “The Sun’s properties are consistent with it being pulled out at random from the bag of all stars,” says Charles Lineweaver from the Australian National University (ANU) in Canberra. “Life does not seem to require anything special in its host star, other than it be close.”

Scientists searching for signs of extraterrestrial life had been focusing their efforts on other Sun like stars in recent times, in the belief life was more likely to exist on any planets that may orbit such stars.
