Other Earth-like planets
Michael Meyer, an astronomer from the University of Arizona, said he believed Earth-like planets were probably very common around Sun-like stars.”Our observations suggest that between 20% and 60% of Sun-like stars have evidence for the formation of rocky planets not unlike the processes we think led to planet Earth,” he said. “That is very exciting.”Mr Meyer’s team used the US space agency’s Spitzer space telescope to look at groups of stars with masses similar to the Sun.
They detected discs of cosmic dust around stars in some of the youngest groups surveyed.
The dust is believed to be a by-product of rocky debris colliding and merging to form planets.

Recently I wrote a post on UFOs and about whether or not there are other alien live forms in our galaxy.
I was quite intrigued when I read this news, and about the possibility of other similar planetary systems in our galaxy. Hmm, could the aliens who travel in these UFOs have come from these other planetary systems?
What an exciting and intriguing idea!
