www.nytimes.com/2016/06/12/opinion/sunday/yes-there-have-been-aliens.html?_r=1Yes, There Have Been AliensBy ADAM FRANK JUNE 10, 2016 LAST month astronomers from the Kepler spacecraft team announced the discovery of 1,284 new planets, all orbiting stars outside our solar system. The total number of such “exoplanets” confirmed via Kepler and other methods now stands at more than 3,000. This represents a revolution in planetary knowledge. A decade or so ago the discovery of even a single new exoplanet was big news. Not anymore. Improvements in astronomical observation technology have moved us from retail to wholesale planet discovery. We now know, for example, that every star in the sky likely hosts at least one planet. But planets are only the beginning of the story. What everyone wants to know is whether any of these worlds has aliens living on it. Does our newfound knowledge of planets bring us any closer to answering that question? A little bit, actually, yes. In a paper published in the May issue of the journal Astrobiology, the astronomer Woodruff Sullivan and I show that while we do not know if any advanced extraterrestrial civilizations currently exist in our galaxy, we now have enough information to conclude that they almost certainly existed at some point in cosmic history. Among scientists, the probability of the existence of an alien society with which we might make contact is discussed in terms of something called the Drake equation. In 1961, the National Academy of Sciences asked the astronomer Frank Drake to host a scientific meeting on the possibilities of “interstellar communication.” Since the odds of contact with alien life depended on how many advanced extraterrestrial civilizations existed in the galaxy, Drake identified seven factors on which that number would depend, and incorporated them into an equation. The first factor was the number of stars born each year. The second was the fraction of stars that had planets. After that came the number of planets per star that traveled in orbits in the right locations for life to form (assuming life requires liquid water). The next factor was the fraction of such planets where life actually got started. Then came factors for the fraction of life-bearing planets on which intelligence and advanced civilizations (meaning radio signal-emitting) evolved. The final factor was the average lifetime of a technological civilization. Drake’s equation was not like Einstein’s E=mc2. It was not a statement of a universal law. It was a mechanism for fostering organized discussion, a way of understanding what we needed to know to answer the question about alien civilizations. In 1961, only the first factor — the number of stars born each year — was understood. And that level of igannance remained until very recently. That’s why discussions of extraterrestrial civilizations, no matter how learned, have historically boiled down to mere expressions of hope or pessimism. What, for example, is the fraction of planets that form life? Optimists might marshal sophisticated molecular biological models to argue for a large fraction. Pessimists then cite their own scientific data to argue for a fraction closer to 0. But with only one example of a life-bearing planet (ours), it’s hard to know who is right. Or consider the average lifetime of a civilization. Humans have been using radio technology for only about 100 years. How much longer will our civilization last? A thousand more years? A hundred thousand more? Ten million more? If the average lifetime for a civilization is short, the galaxy is likely to be unpopulated most of the time. Once again, however, with only one example to draw from, it’s back to a battle between pessimists and optimists. But our new planetary knowledge has removed some of the uncertainty from this debate. Three of the seven terms in Drake’s equation are now known. We know the number of stars born each year. We know that the percentage of stars hosting planets is about 100. And we also know that about 20 to 25 percent of those planets are in the right place for life to form. This puts us in a position, for the first time, to say something definitive about extraterrestrial civilizations — if we ask the right question.

Our Milky Way galaxy in Infrared taken with the Spitzer Space Telescope. Our nearest neighbor galaxy to the Milky Way ( M31 ) the Andromeda Galaxy taken with the Hubble Space Telescope. Enjoy the view.

I don't remember where I heard this..but it's said that when a new star is born all of the angels go to welcome it. It's a lovely thought...

I have never publicly come forward about this, but will now, to you. My Mom passed away on Dec 25th, 2014. (Christmas) Ironically, I could not cry. I could only smile KNOWING that amazing woman is in heaven.....I'm sure mother Mary herself was waiting to greet her and to give her a hug and let her know " well done ".

My husband will be on his way very soon also..and it can only be a blessing because he struggles day in and out to breathe. I cannot possibly be sad when I know only too well that we're just moving on and his struggles will have ended in something amazing and wonderful. As this worsens..and congestive heart failure combined with COPD is horrific..(Leonard Nimoy too) I won't be here so much if at all for awhile.. I'll be back...I'll need to be.

I guess the theory is that if life exists..it should show up here? How very arrogant. By 'space' standards..we could be the equivalent of distant backwoods kin..or have literally nothing in common with 99 percent of life out there. WE jump to the assumption they would be like us...naturally 'us' being the preferred and special form life should take. People here do it all the time..unless you fit the 'standard' you're a lesser version of humanity. Galaxies and galaxies maybe multi universes..to house people who could care less..if life exists on this chunk of rock...having their own lives..not needing ours. Maybe those who have been or are still visiting..see the direction we're moving in and find it as abhorrent as I do. We have a lot of growing to do but at the same time..we think we're 'all that'...brilliant minds..scientists achieving miracles..maybe..on their scale we're not miraculous at all but children playing with matches.
