Great googly moogly! Scientists believe they have found evidence of water in the atmospheres of planets orbiting distant stars
Having water does not mean other planets will be teeming with life but if the discovery is confirmed it will fuel speculation that it could be possible.
News of this nature never ceases to thrill me. When I was a youngster, I watched the last few Apollo moon landings and wanted to be an astronaut. Back then, we had no evidence at all of planets outside the solar system, although astronomers widely believed they must exist, as Carl Sagan noted in the Cosmos TV series. .
Heck, 100 years ago we didn't even know about all the planets in our own Solar System.
Our current ability to gather such vast amounts of information about distant planets will only narrow down the possible candidates for interstellar probes--rather than taking a non-cost-effective scattersot approach, we can send probes to solar systems deemed most likely to support life.
