It's a potentially habitable planet that's orbiting a nearby star, that's capable of having liquid water and thus supporting life as we know it.
In the Huffington Post, Mike Wall quotes astronomer Steve Vogt as saying, "This discovery is in keeping with our emerging view that virtually every star has planets, and that the galaxy must have many such potentially habitable Earth-sized planets. They are everywhere, even right next door."
He quotes astronomer Mikko Tuomi as saying, "It is impossible to tell the composition, but I do not consider this particular planet to be very likely to have a rocky surface. It might be a 'water world,' but at the moment it's anybody's guess."
If Tau Ceti planets do exist, their proximity would make them prime targets for future instruments to study (and for us to travel to?)
Wall quotes astronomer James Jenkins as saying, "Planetary systems found around nearby stars close to our sun indicate that these systems are common in our Milky Way galaxy." In other words, there could be LIFE all around us--we just haven't found it yet!
So why aren't we out in space looking? In 1998, a mysterious man that Whitley Strieber calls the Master of the Key burst into his hotel room in Toronto and told him all kinds of things he didn't know--but when he checked them out later, he found out they were TRUE. One of the few things that Whitley could NOT check out was MOTKE's provocative statement that we are stuck on this planet because the parents of the child who would have given us the ability to travel into space was killed in the holocaust!
