February 20, 2008 With upwards of 100 billion stars in our own Milky Way and at least that number of galaxies in the observable universe, the odds have long pointed to the likely existence of planets beyond our own solar system. The first discovery of such an extra-solar planet to receive subsequent confirmation took place in 1988 and two decades later, as detection techniques and equipment continue to improve, that number is now approaching 300. Now news that Astronomers from the University of St Andrews have found a new planetary system some 5,000 light years away that bears "striking similarities" to our Solar system.
