Princeton Study
Using what is known as Bayesian analysis which weighs how much of a scientific conclusion comes from actual data and how much comes from prior assumptions of scientists, researchers at Princeton University sought to determine the probability of extraterrestrial life with these presumptions minimized. Edwin Turner, professor of astrophysical sciences and David Spiegel participated in the study. Familiar with the research is Joshua Winn, associate professor of physics at the Massachusetts Institute of Technology who said,
WW
There is a commonly heard argument that life must be common or else it would not have arisen so quickly after the surface of the Earth cooked. This argument seems persuasive on its face, but Spiegel and Turner have shown it doesn’t stand up to rigorous statistical examination—with a sample of only one life-bearing planet [Earth], one cannot even get a ballpark estimate of the abundance of life in the universe.
Just Us
With this expanded comprehensive perspective, no longer can I be as sure as I once was; some of my own limited presumptions were at work. So it takes me to a place where I now ask, “Are we really alone in this staggeringly vast ether of space? Are we a cosmic aberration?” I think of these words from the movie Contact that say it all, “If it’s just us…seems like an awful waste of space.”
http://www.joearrigo.com/2012/11/20/are-we-a-lone-life-ship-in-the-milky-way-galaxy/ I've always felt the same way. But I'm accepting the possiblity of EarthSeed more and more. While these observations tend to stoke the expectation of finding Earth-like life, they do not actually provide evidence that it does or does not exist, Spiegel explained. Instead, these planets have our knowledge of life on Earth projected onto them, he said. Yet, when what is known about life on Earth is taken away, there is no accurate sense of how probable abiogenesis is on any given planet, Spiegel said. It was this "prior ignorance," or lack of expectations, that he and Turner wanted to account for in their analysis, he said. "When we use a mathematical prior that truly represents prior ignorance, the data of early life on Earth becomes ambiguous," Spiegel said. "Our analysis suggests that abiogenesis could be a rather rapid and probable process for other worlds, but it also cannot rule out at high confidence that abiogenesis is a rare, improbable event," Spiegel said. "We really have no idea, even to within orders of magnitude, how probable abiogenesis is, and we show that no evidence exists to substantially change that."

Tonight Venus and Jupiter will merge and form a "double star". This phenomenon will be visible to the naked eye in the Western sky. If you have a pair of binoculars handy, or, better yet, a telescope, you can have a peek at the pair and hopefully even see Jupiter's four moons. This converging in the sky is known as a conjunction. A conjunction between Jupiter and Venus is not unusual; the duo were last seen close together in the sky on August 18, 2014. Fortunately, if you miss this sighting and you missed the one in 2014, Venus and Jupiter have scheduled another date for the morning of October 26, 2015. On this day, they will be separated by 1°. And if you still can't see this meeting, then next year, on August 27, the planets will reunite once again. Here they will be separated by a stunning 0.1°.

I never read that stuff about those people that believe the earth is flat, but after reading "some" of this (there's attachements and such I haven't gotten to) I'm beginning to wonder, about their thinking. What these people sit around their "coffee bars" and talk, geesh. Some physicists believe we're living in a giant hologram — and it's not that far-fetched
That's still a matter of active debate. But there's been some recent theoretical work that suggests the holographic principle might work for our universe too — including a high-profile paper by Austrian and Indian physicists that came out this past May...

cool thread, thanks for excellent links morningsong. i love living in an era when space exploration is possible and we can dial up the net to look at the images. think of all those brilliant atronomers in years gone by who had nothing more than highly polished glass telescopes. little peephole windows. now we're sending unmanned exploration craft to distant targets. way cool. first littlest steps out and about.

NASA‘s New Horizons proposals will use fictional characters and locations, including from Tolkien’s Middle-earth, to name features of Pluto and its moons next week. In their proposed themes for Pluto, they have “Underworld beings” which includes Morgoth and Balrogas suggestions; for Charon a theme is “Fictional Origins and Destinations” which includes Shire andMordor; and for Hydra the theme is “Legendary Serpents and Dragons” which includes Smaug. It’s not just Tolkien that features, though. Other notable suggestions include: Niflheim in the “Underworlds and Underworld Locales” theme; Heracles in the “Travelers to the Underworld”; Kirk,Spock, Skywalker, Dorothy and Alice in “Fictional Explorers and Travelers”; Gallifrey, Krypton, Hoth,Tatooine and Vulcan in “Fictional Origins and Destinations”; Tardis, Argo, Dutchman, and Galactica in “Fictional Vessels”; and Toto in “Dogs from Literature, History and Mythology”.

New Horizon will pass by Pluto at its closes on Tuesday. It is only making a flyby, it will not be orbiting, then it'll make its way deeper into the Kuiper Belt Post-KBO missionEdit Provided it survives, New Horizons is likely to follow the Voyager probes in exploring the outer heliosphere and mapping the heliosheath and heliopause. The heliopause might be reached around 2047.[128] Even though it was launched far faster than any outward probe before it, New Horizons will never overtake either Voyager 1 or Voyager 2 as the most distant human-made object from Earth. Close fly-bys of Saturn and Titan gave Voyager 1 an advantage with their gravity assist. When New Horizons reaches the distance of 100 AU, it will be travelling at about 13 km/s (29,000 mph), around 4 km/s (8,900 mph) slower than Voyager 1 at that distance.[129] (1 AU is equivalent to the distance of Earth from the Sun) [Edited 7/12/15 0:13am] | |

SRIHARIKOTA: Indian Space Research Organization's commercial launch capability reached a new high on Friday night when it successfully launched five satellites for the UK. Polar Satellite Launch Vehicle (PSLV-C28) lifted off from the Satish Dhawan Space Centre in Sriharikota at 9.58pm. Less than 20 minutes later, the rocket placed in the designated orbits three identical DMC3 optical earth observation satellites, an auxiliary earth observation micro satellite (CBNT-1) and one technology demonstrator nanosatellite (De-OrbitSail), built by SSTL. It was PSLV's 30th flight and 29th consecutive successful one. For the ninth time, Isro used an XL version of the rocket with an additional strap-on. The heaviest commercial mission undertaken by the space agency underlines Isro not only as a major player for space industries globally but also as a leading foreign exchange earner for the country. Earlier, Isro launched SSTL's and SSC's (Surrey Space Centre) nanosatellite STRAND-1 on February 25, 2013. The other countries which have launched their satellites using Isro's launch facilities include Germany, Republic of Korea, Belgium, Indonesia, Argentina, Italy, Israel, Canada, Japan, The Netherlands, Denmark, Turkey, Switzerland, Algeria, Singapore, Luxembourg, France and Austria. | |

Okay, enough of that. Onwards... Professor Johann-Dietrich Woerner has been in his new job as Director General of the European Space Agency (Esa) for a week. In charge of a €4.4 billion annual budget, the former Chair of the German space agency is ultimately responsible for everything at Esa. Europe’s new observation, weather, communication and navigation satellites; astronauts on the International Space Station (ISS); missions to Mars, Mercury and Jupiter; and a sleepy lander on a duck-shaped comet all come under his remit. When I ask him about his intentions for Esa, I expect a predictable and politically nuanced answer about the economic and social benefits of space or maybe the importance for science of exploring the unknown Universe. Instead, Woerner surprises me with a vision for a future of space exploration that is both ambitious and audacious. “We should look to the future beyond the International Space Station,” he tells me. “We should look for a smaller spacecraft in low-Earth orbit for microgravity research and I propose a Moon village on the far side of the Moon.” Yes, a village on the Moon.
Just the sort of daring vision that took Nasa from a standing start to the Moon in the 1960s, but today – possibly constrained by its political masters – the US space agency appears to be lacking ambition. “A Moon village shouldn’t just mean some houses, a church and a town hall,” says Woerner. “This Moon village should mean partners from all over the world contributing to this community with robotic and astronaut missions and support communication satellites.”

Astronomer, actor, role model: TED Fellow Aomawa Shields looks for life on other planets Posted by: Karen Eng July 10, 2015 at 10:00 am EDT Aomawa Shields is a woman of “contradictions.” An astronomer and astrobiologist, she searches for exoplanets where life might exist by using computer models to calculate the kind of atmosphere they’d need to support it. And she’s also a classically trained actor, who — through her organization Rising Stargirls — teaches astronomy to middle school girls of color using theater, writing and visual art to spark their imaginations. She talks to the TED Blog about how the threads of her life — scientist, actor, role model and educator — weave together into a unique whole. “Astrobiology” is a new word to me. What does it mean? Astrobiology is the study of the origin, evolution, distribution and future of life in the universe. It’s a huge topic. Astrobiologists come from all different primary fields — I have an astronomy background, but there are also geologists who become astrobiologists as well as oceanographers, chemists and biologists. We’re all working together to answer the question: “Are we alone in the universe?” And also: “How do we go about answering that question?” Some of these experts focus on the origin of life: How did life even get started on our planet? Others think about metabolism: How does life evolve, use its energy and carry out the reactions that it needs to feed, grow, reproduce and respond to its environment? Are there different kinds of metabolisms besides what we know here on Earth that life could use? It’s important to ask that question, because we don’t want to miss out on discovering life because it uses different chemical processes from life as we know it, or because it is not carbon-based, or because it uses something besides water to carry out molecular processes. We have all these planets that have been discovered, but we can’t look at all of them in detail to try to measure their atmospheric composition and determine if there’s life there. So I’m a big proponent of using a combination of observational astronomy and theoretical astronomy techniques to help us narrow in on the planets most likely to have water and life. Finding them is the first step, and it’s an important, crucial step — but it’s not the whole story. Identifying a planet as “potentially habitable” does not mean it’s “habitable,” and “habitable” does not mean “inhabited.” That’s something that the public can get really confused by. http://blog.ted.com/ted-f...ign=buffer | |
