Exploring  Galactic  Space  Life

"One great leap toward the possibility of life, including intelligent life, in the universe," said University of California Berkeley astronomer Geoffrey Marcy, who worked on a new study in the Proceedings of the National Academy of Sciences. The new planetary study used the Kepler space telescope, NASA's primary planet-hunting tool l to gather the data over several years. A November 4, 2013 Los Angeles Times Newspaper article explained, "Since its launch in 2009, Kepler has helped uncover a "bewildering variety" of alien worlds throughout the Milky Way, said William Borucki, lead scientist for the Kepler mission at NASA's Ames Research Center in Mountain View, Calif. Many in this strange menagerie which includes mini-Neptunes and super-Jupiters are not like any of the planets in our solar system. Some distant planets may be composed entirely of water; others have densities greater than iron or lower than Styrofoam."     Information source: "http://articles.latimes.com/2013/nov/04/science/la-sci-earth-like-planets-20131105">

In 1960, one of the leaders in technically exploring spece, Dr. Frank Drake, had joined the National Radio Astronomy Observatory. At the Search for Extraterrestrial Intelligence conference (SETI) in 1961, he demonstrated his formula of a complex set of mathematical calculations to estimate the number of intelligent communicating civilizations possible in just the Milky Way galaxy. Drake's work is primarily directed toward detecting and sending radio signals for direct communication. Any planetary radio signals detected today on earth could have been traveling for unknown light years.

The Drake Equation is important because it considers a variety of Milky Way factors including the estimated 100 billion stars, number of stars with planetary systems, how many planets would be able to sustain life, how much life would be intelligent life and of those how many could communicate. A source calculated there were possibly as many as 10,000 Intelligent Civilizations in the Milky Way. It is also still important because it opens scientific discussions about the likelihood of other life out there.

Fifty six years later, in 2016 an updated analysis of the Drake equation provided a new layer of understanding of possible far off civilizations. Marc Dantonio, Exoplanet Researcher, in a The Huffington Post article. explained the new analysis "doesn't make the Drake obsolete but instead creates another 'new edition' that helps us predict the probability of detecting other civilizations," The expanded knowledge of space in those 56 years due improved technologies and man's journeys into space have enhanced the Drake Equation concepts. He reported that a 'new edition' equation study by Sara Seager, astrophysicist and planetary scientist at the Massachusetts Institute of Technology, concluded, “our galaxy alone has between 100 and 400 billion stars. So on the low end of the estimate of only 100 billion stars her analysis predicts just over 6.5 million possible civilizations and at the higher end estimate of 400 billion stars in the galaxy, 26 million possible systems with intelligence are predicted. What does this all mean? It means, significantly, that science is on the side of those who suspect that there is other reasonably intelligent life in the Universe."

Discoveries by archaeologists worldwide over several centuries have led to strong beliefs that during the human history of the earth, advanced Extra-Terrestrial Life visitors from other planets possibly including other from galaxies interacted with humans.It should be considered very possible that other life form visitors from the reaches of space have successfully traveled to observe or visit this earth for thousands of years. There have been ample historical beliefs of Extra-Terrestrial Life visitors observing the earth and its inhabitants. Their technical skills and their physical compositions would be highly developed to overcame the challenges of space and time.

For Earth humans today, those history time lines galactic life possibilities are difficult to imagine. Putting Earth's human history into perspective. the human explorer Columbus crossed the Atlantic Ocean from Europe to North and South America only 524 years ago. Wright's flight of 120 feet in the air by a powered device occurred only 115 years ago. Human exploration and understanding of "space" today during the past sixty years is still in its infancy. Have "other reasonably intelligent life forms" been impressed by human progress on planet Earth?
