The existence of life outside our planet just got a bit more likely.
Following years of finding planets around other stars, a new study thinks that every star has planets which form from the remaining material in the gas/dust cloud that formed the star. The study – originally published in Nature magazine is also discussed in this BBC News article.
That means there are likely 10 Billion (10,000,000,000) planets that are like Earth in size. Many of those could be the right temperature and have the right chemistry for life to have developed.
One thing to bear in mind – we currently don’t know how to travel faster than light so even if aliens do exist – unless they do know how we might never meet them.
