If your a pet lover you would know how good the feeling you get when you pet one. That's why I decided to join this organization. So if you want to donate to pets in shelters go to ABOUT at the top and all the way down is donor box there you can donate. And thank YOU SO MUCH!!!Many other planets throughout the universe probably hosted intelligent life long before Earth did, a new study suggests.
The probability of a civilization developing on a potentially habitable alien planet would have to be less than one in 10 billion trillion — or one part in 10 to the 22nd power — for humanity to be the first technologically advanced species the cosmos has ever known, according to the study. "To me, this implies that other intelligent, technology-producing species very likely have evolved before us," said lead author Adam Frank, a professor of physics and astronomy at the University of Rochester in New York. [13 Ways to Hunt Intelligent Alien Life] Advertisement Do you believe alien life exists elsewhere in the universe?
"Think of it this way: Before our result, you’d be considered a pessimist if you imagined the probability of evolving a civilization on a habitable planet was, say, one in a trillion," Franksaid in a statement. "But even that guess — one chance in a trillion — implies that what has happened here on Earth with humanity has in fact happened about 10 billion other times over cosmic history." In 1961, astronomer Frank Drake devised a formula to estimate the number of extraterrestrial civilizations that may exist today in the Milky Way. Adam Frank and co-author Woodruff Sullivan of the University of Washington were interested in the odds that intelligent aliens have ever existed anywhere in the universe. So they tweaked the famous Drake equation, coming up with an "archaeological version" that doesn't take into account how long alien civilizations may last. Frank and Sullivan also incorporated observations from NASA's Kepler space telescope and other instruments, which suggest that about 20 percent of all stars host planets in the life-friendly, "habitable zone," where liquid water could exist on a world's surface. The researchers then calculated the probability that Earth was the universe's first-ever abode for intelligent life, after taking into account the number of stars in the observable universe (about 20 billion trillion, according to a recent estimate). "From a fundamental perspective, the question is, 'Has it ever happened anywhere before?'" Frank said. "Our result is the first time anyone has been able to set any empirical answer for that question, and it is astonishingly likely that we are not the only time and place that an advanced civilization has evolved." But this doesn't mean that there are lots of intelligent aliens out there, just waiting to be contacted, the researchers stressed. "The universe is more than 13 billion years old," Sullivan said in the same statement. "That means that even if there have been 1,000 civilizations in our own galaxy, if they live only as long as we have been around — roughly 10,000 years — then all of them are likely already extinct. And others won’t evolve until we are long gone. For us to have much chance of success in finding another 'contemporary' active technological civilization, on average they must last much longer than our present lifetime." (The 10,000-year figure cited by Sullivan refers to humanity's development of agriculture and other "rudimentary" technologies; mankind has been capable of sending radio waves and other electromagnetic signals out into the cosmos for just a century or so.) The new study has been published in the journal Astrobiology; you can read it for free here. JAXA lost contact with the satellite on March 26 during a routine maneuver to reorient the spacecraft to look at a different region of the sky. The agency was initially cautiously optimistic about restoring control of the spacecraft, stating it had received three brief signals in the days after the anomaly it thought it was the spacecraft.
However, in its April 28 statement, JAXA said it concluded the signals it detected were not from Hitomi at all because they were not at the wrong frequencies. “JAXA will cease the efforts to restore ASTRO-H and will focus on the investigation of anomaly causes,” the agency stated. “We will carefully review all phases from design, manufacturing, verification, and operations to identify the causes that may have led to this anomaly including background factors.” According to an April 15 briefing posted on the JAXA website, investigators believe a chain of errors with the spacecraft’s attitude control system caused the spacecraft to spin up enough for the solar panels and other components to break off. The problem started when Hitomi’s attitude control system determined the spacecraft was rotating after a planned maneuver, when in fact it was not. That system activated a reaction wheel to stop the phantom spin, which created a real spin. That spin saturated the reaction wheel, triggering a “safe hold” mode in the spacecraft. The spacecraft fired thrusters in its reaction control system to halt the spin, but an incorrect control parameter in that system instead caused the spacecraft to spin even faster. Investigators believe that spacecraft controllers updated the parameter to reflect a different spacecraft configuration after the deployment of an instrument boom, but may have done so incorrectly. The loss of Hitomi is a setback not just for JAXA, but also for several other space agencies. The x-ray astronomy satellite included contributions from NASA, the European Space Agency and the Canadian Space Agency, including an x-ray instrument developed at NASA’s Goddard Space Flight Center. For x-ray astronomers, Hitomi was one of the biggest missions this decade. “JAXA expresses the deepest regret for the fact that we had to discontinue the operations of ASTRO-H,” the agency said in its statement, “and extends our most sincere apologies to everyone who has supported ASTRO-H believing in the excellent results ASTRO-H would bring, to all overseas and domestic partners including NASA, and to all foreign and Japanese astrophysicists who were planning to use the observational results from ASTRO-H for their studies.” OneWeb made its filing under its originally incorporated name, WorldVu Satellites Ltd., and has hired Milbank, Tweed, Hadley & McCloy LLP and Wiley Rein LLP as legal counsel for the procedure. OneWeb’s newly announced Florida satellite facility is scheduled to be starting high-rate production to meet the company’s schedule of launching 720 satellites between early 2018 and the end of 2019. To meet that schedule, OneWeb is working on multiple fronts. OneWeb Chief Executive Matt O’Connell said the company had begun preparing a second around of financing and had hired Deutsche Bank and Barclays to sound out investor interest in OneWeb’s project, whose ultimate goal is providing broadband access to the most isolated of rural communities. OneWeb in June 2015 raised $500 million from mainly strategic investors, meaning companies whose financing was in part done to guarantee them a role on OneWeb’s contracting team. But the investors also included cellular network operators Bharti Enterprises of India and Grupo Salinas of Mexico – companies that can be of help to OneWeb as it seeks regulatory approval in each nation in which it plans to operate. O’Connell said the absence of financial investors from the first round was not a concern. “It makes more sense for strategic investors to get things going,” O’Connell said. “When I was in venture capital our pitch was: Anyone can give you money. What you want is a smart investor with skin in the game, who can offer you more than money.” OneWeb’s constellation consists of 720 satellites – 40 spacecraft in each of the 18 orbital plans – in low Earth orbit, covering every corner of the globe. The track record of other satellite operators seeking approvals in nations such as India and China – the biggest and among the most difficult for foreigners to enter – suggests that the OneWeb regulatory battle will be long. But O’Connell – who was hired perhaps as much for his investment banking background as for his former role as chief executive of geospatial imaging provider GeoEye — said the company would begin as a business-to-business offer to small and midsize companies. Much of the legwork in securing licenses will be done by OneWeb’s local partners. O’Connell said OneWeb founder Greg Wyler’s vision of broadband for every poor village is as valid as ever, but will be realized only after OneWeb secures a place in the market.The solar system is made up of the sun and everything that orbits around it, including planets, moons, asteroids, comets and meteoroids. It extends from the sun, called Sol by the ancient Romans, and goes past the four inner planets, through the Asteroid Belt to the four gas giants and on to the disk-shaped Kipper Belt and far beyond to the giant, spherical Oort Cloud and the teardrop-shaped Heliopolis. Scientists estimate that the edge of the solar system is about 9 billion miles (15 billion kilometers) from the sun.Thanks for visiting be sure to take the survey, because every submission that we get we give charity $100. |
