NASA announces 7 more earthlike exoplanets
Talk about lucky number seven. Astronomers have discovered not one, not two, but seven Earth-sized planets orbiting a star called TRAPPIST-1.
What’s more, three of them are in the habitable zone— the happy place where liquid water can exist on the surface of rocky planets, as it’s not too hot or cold.
“The discovery gives us a hint that finding a second Earth is not just a matter of if, but when,” Thomas Zurbuchen, associate administrator of the Science Mission Directorate at NASA Headquarters, said at a news conference announcing the discovery.
Zurbuchen called it a "major step forward" towards the goal of answering the very big question: Is there life on other worlds?
The discovery "is very promising for the search for life beyond our solar system,” Michael Gillon, astronomer at the University of Liege in Belgium, added during the press conference.
This is the first time astronomers have found so many Earth-sized planets circling the same sun.
Since the seven planets orbit the star-- which is roughly 40 light years away-- fairly close to each other, the view from one planet would reveal another planet to look as big, if not bigger, than the way we see the moon.

6. Well, we *might* be able to build something that can go a tenth the speed of light in the next
century or so....so we should be able to get there in 2500 AD.
Give or take.

2. There really is intelligent life somewhere!!!! Maybe
I feel better now, this is great discovery and causes me to have hope that there is intelligent life somewhere. I do not know if it is on any of these plants but perhaps it is. it certainly does not seem there is much of it here......Anyway I know life is abundant and this is just an awesome discovery even if we cannot confirm life we can confirm that we are not so unique after all and that is always good.....
