A couple of months ago top U.S. astronomers gathered in front of congress to let them know that extraterrestrial life exists without question. Their main argument was the size of the universe, emphasizing that there are trillions of stars out there, with one in every five most likely harboring an Earth-like planet. It’s also important to keep in mind that planets do not have to be “Earth-like” in order to harbor life. You can read more about that story here.
“The number of habitable worlds in our galaxy is certainly in the tens of billions, minimum, and we haven’t even talked about the moons. And the number of galaxies we can see, other than our own, is about 100 billion.” – Seth Shostak, Senior Astronomer at California’s SETI Institute (source)
This time, NASA and the Library of Congress have teamed up bringing together scientists, theologians, philosophers and historians from around the globe for a two day symposium in order to discuss how to prepare the world for extraterrestrial contact, whether it be microbial organisms or intelligent beings.
For the rest of the story: http://www.wakingtimes.com/2014/09/26/nasa-brings-scientists-theologians-together-prepare-world-extraterrestrial-contact/“We’re looking at all scenarios about finding life. If you find microbes, that’s one thing. If you find intelligence, it’s another. And if they communicate, it’s something else, and depending on what they say, it’s something else! The idea is not to wait until we make a discovery, but to try and prepare the public for what the implications might be when such a discovery is made. I think the reason that NASA is backing this is because of all the recent activity in the discovery of exoplanets and the advances in astrobiology in general. People just consider it much more likely now that we’re going to find something — probably microbes first and maybe intelligence later. The driving force behind this is from a scientific point of view that it seems much more likely now that we are going to find life at some point in the future.”
