Terra Nova
NASA has discovered the first Earth-like world in the "habitable zone" - not too close to its star; not too far away (this allows for liquid water and, presumably, the possibility of life).
Extra points for Tim Wolter who noticed they said a galaxy 100 light years away.
We don't have any way of getting close to light speed and it would take generations to get there even if we could do .9C. Figure a couple of years to accelerate to final speed and then to decelerate with 110 to 115 years for the voyage.
Physics is such a bitch.
It's interesting, but essentially useless information. Like knowing the next city over has power after the storm has knocked yours out.
I keep thinking of Larry Niven and his 'habitable worlds' discovered by robot probes - Jynx - oblong planet, equator is venus like, poles are outside of the atmosphere and in vaccum- two narrow bands north and south support life. 'We made It' - livable but desert for 6 months of the year. 1500mph winds for the rest of the year.
If it has sapient inhabitants with access to radio, they should be receiving our earliest transmissions.
ReplyDeleteNow it's going to get interesting... :-)
ReplyDelete"In a galaxy 100 light-years away in the constellation Dorado..."
ReplyDeleteUh....another galaxy 100 light years away? Seriously NASA, who's doing your social media? Or worse yet, your math?
