Other Earths

Our star, the sun, is just one of trillions in the universe. When you look at the fact that our star has eight planets, and do the math, it tells you that it is possible for there to be eight times as many planets in the universe than stars; an astounding figure. Is it not possible that just one of those planets might have life on it? It is a fact that, since the year 2000, hundreds of extra solar planets have been discovered orbiting distant stars. Some of these have found to be earth- like, such as the planet Gliese 581d, a planet believed to have liquid water on its surface. Could it possibly contain life? Hopefully with advances in technology in the next decade, we will soon know the answer. Till then, it remains one of space’s greatest mysteries.
