(Visited 64 times, 1 visits today)FacebookTwitterPinterestSave分享0 Planetary scientists have figured out that the geysers of Enceladus vary during its orbit, but seem oddly silent about the question of how long the little moon could remain so active.Cassini scientists have observed the brightness of the Enceladus geysers for several years now, from various angles. It appears, according to a new paper in Nature, that the geysers are brightest when the moon is farthest from Saturn. They suspect that the southern-hemisphere cracks or “tiger stripes” are under tension at that point, opening them up for greater escape of salty water. When Enceladus is closer to Saturn, the cracks are under compression and close up a bit more, like a constricting hose nozzle. This is explained in another Nature article by John Spencer, who also suggested that the findings hint “at a subsurface source of liquid water and a probable subsurface ocean.”Whether Enceladus has an ocean remains debatable, however. A recent paper in Icarus found that the only way to sustain a liquid ocean under the crust was to assume that the ice is not as elastic as previously assumed—and then, only under specific conditions:Though anelastic behavior increases the heating rate, it is insufficient to maintain a global subsurface ocean if the ice layer is convecting, even though a wide parameter range is taken into account. One possibility to maintain a global ocean is that Enceladus’ ice shell is conductive and its tidal response is similar to that of the Burgers body with comparatively small transient shear modulus and viscosity. If the surface ice with large viscosity is dissipative by anelastic response, the heat produced in the ice layer would supersede the cooling rate and a subsurface ocean could be maintained without freezing.Water = life?The popular press reported the findings about the orbital variability of the geysers, but said nothing about the sustainability of this level of activity for billions of years. Instead, they latched onto the suggestion that Enceladus might have a liquid ocean, implying it might have life. A BBC News article, for instance, focused attention on Spencer’s brief suggestion about this:“The likely presence of liquid water and complex organic chemistry makes Enceladus especially intriguing as a potential habitat for extraterrestrial life, providing additional motivation for investigating its interior.”Science Daily, regurgitating a JPL press release, quoted paper co-author Christophe Sotin:“Liquid water was key to the development of life on Earth, so these discoveries whet the appetite to know whether life exists everywhere water is present.”None of the papers or articles, however, addressed the more perplexing question of how Enceladus could maintain this level of activity for billions of years. Ever since the geysers were detected in 2005, it has been a major mystery to account for the sustainability of such activity for long ages (search “Enceladus” in these pages, e.g., 4/06/13, “Bimbo Eruptions in the Solar System”).Et tu, Dione?An earlier article on Science Daily reported that Saturn’s larger moon Dione might also have activity–also ignoring the age question, but leaping onto the life suggestion:Other bodies in the solar system thought to have a subsurface ocean — including Saturn’s moons Enceladus and Titan and Jupiter’s moon Europa — are among the most geologically active worlds in our solar system. They have been intriguing targets for geologists and scientists looking for the building blocks of life elsewhere in the solar system. The presence of a subsurface ocean at Dione would boost the astrobiological potential of this once-boring iceball.The Nature paper about Enceladus said nothing about life, oceans, or habitability – but it ignored the age question, too.Talk of biology and “building blocks of life” at the mere hint of water is a classic red herring, a distraction or sidestep around the major conundrum facing planetary scientists: how to keep Enceladus going for billions of years. It’s not a problem for Biblical creationists who expect Enceladus, Io and the other active bodies in the solar system to be thousands of years old but it’s a major problem for secularists who count ages in billions. We need a new word to describe this tactic of quickly focusing on life whenever water is suspected on another world. How about “hydrobioscopy“? We’ll add that to our Darwin Dictionary.There’s no way evolutionists and other secular scientists could face up to this hard evidence if it might give aid and comfort to their sworn enemies, so they change the subject rapidly, thinking that talk of the possibility of life on a frozen, airless world might be more sexy than hand-wringing in public over the falsification of their long-age beliefs. For comfort, they run to gulp down more Darwine. We need to hold their feet to the fire, not their mouths to the firewater.
Google is announcing a new contest for local would-be heroes.The Map Maker Global Competition, which challenges users to add high-quality data on universities, schools, hospitals and medical clinics in Google Map Maker, will run from Dec. 15, 2009 to Jan. 31, 2010. The grand prize for the user who adds the greatest quantity of data is a $50,000 UNICEF donation to the winner’s home country.The winning team or user will moreover receive a VIP tour from UNICEF officials of the local projects that will benefit from the donation as well as an all-expenses-paid trip to the Google Super Mappers 2010 conference. Top mapping contributors will appear on Google Map Maker and ultimately on Google Maps.Google’s Map Maker shows users satellite images and asks them to add data to make actually useful maps. These citizen cartographers can add directions, streets, schools and more; data is subject to peer moderation. The app is available in English, Spanish, French, Russian, Romanian and Vietnamese, and in more than 170 countries. UNICEF representative Gerrit Beger told Google, “We know that mapping is a proven method to enhance community development. Google Map Maker is a powerful tool to create better situational awareness for both young people and communities at large. It will enable organizations like ours to better deliver services, respond to crises and adapt to change.”Google has also just wrapped up a similar competition focusing on Latin America. In that event, more than 50 teams from all over the world participated, which led to a 500 percent increase in mapping activity for several Latin American countries.

OTTAWA — Caitlan Coleman denies trying to use her husband Joshua Boyle as a bargaining chip to get chocolate while the pair were held captive by extremists.Coleman told Boyle’s assault trial in Ontario court today there is no truth to his claim she attempted to get the treat in exchange for Boyle’s participation in a mock execution by their Taliban-affiliated captors.Coleman testified via video link from the United States as lawyers wrapped up their re-examination of witnesses in the case.Boyle, 36, has pleaded not guilty to offences against Coleman, including assault, sexual assault and unlawful confinement in the period of October to December 2017.The incidents are alleged to have taken place after he and Coleman returned to Canada five years after being taken prisoner in Afghanistan during a 2012 backpacking trip through central Asia.Coleman said today she was hoping the couple would be denied permission to enter Afghanistan, contradicting Boyle’s testimony earlier in the trial they were both keen to visit the strife-torn country.This report by The Canadian Press was first published Sept. 30, 2019.The Canadian Press
New Real Madrid manager Julen Lopetegui is set to face an awkward first meeting with Cristiano Ronaldo after having proclaimed his rival Lionel Messi “the best player of all time”To the shock of many, Lopetegui was announced as Zinedine Zidane’s replacement for next season and will officially commence his duties at Real after the World Cup.The current Spain boss has previously spoken of his admiration for Messi in the past on various occasions and has emphasised his belief that the Barcelona star has no equal in this world.“It’s extremely unlikely that we’ll see another player like him,” said the new Real boss.Prior to his appointment with the European champions, Lopetegui had an interview with the Spanish news publication “20 Minutos” and he again praised Messi.“He’s made the difference in so many ways over a continuous period of time” and that it’s “a joy to watch him play”.Fiorentina owner: “Ribery played better than Ronaldo!” Andrew Smyth – September 14, 2019 Fiorentina owner Rocco Commisso was left gushing over Franck Ribery’s performance against Juventus, which he rates above that of even Cristiano Ronaldo’s.The upcoming World Cup may be Messi’s last chance to win it with the five-time Ballon d’Or winner now in his thirties.But Lopetegui is certain that the Argentina team can challenge at Russia with their “extraordinary squad with extraordinary players”.Lopetegui: “Messi es el mejor jugador de la historia” pic.twitter.com/Qul7F3Ahqv— Manipulando (@Manipulando_) June 12, 2018
Spain boss Fernando Hierro has confirmed that he will be sticking with David de Gea as his starting goalkeeper for their upcoming last of 16 tie against Russia after reports had emerged that he was planning to drop himThe Manchester United number one made a high-profile error in La Roja’s opening game of the World Cup against European champions Portugal with Cristiano Ronaldo’s shot slipping right through his hands for the Real Madrid star’s second of the match.Since then, De Gea has conceded another two goals in Spain’s 2-2 draw with Morocco and has looked like he is short of confidence right now.Reports had emerged suggesting that Hierro was planning to remove De Gea from the spotlight and instead start Athletic Bilbao’s Kepa Arrizabalaga in his place.Quiz: How much do you know about David Villa?

The Brazilian footballer spent only one season with the Spanish La Liga team before moving to Internazionale MilanRonaldo Nazario de Lima played for Spanish La Liga club Barcelona in the 1996-1997 season.While there, he scored 34 goals in 37 matches.And many fans thought he would stay for many years with the Blaugrana.But in an interview with Goal, former Barca president Joan Gaspart revealed how the Brazilian went to the Italian Lega Serie A.“Ronaldo wanted to stay at Barcelona, he was happy and his wish was to renew,” Gaspart said.“We had even typed out the contract in front of the player himself and his two agents.”Capello calls Lukaku “a modern striker” Manuel R. Medina – September 14, 2019 The former Italian manager believes Romelu Lukaku is perfectly suited for Antonio Conte’s Internazionale Milan in the Serie A.“It was three in the afternoon and we justifiably decided to go out to eat and celebrate Ronaldo’s renewal, and then return to the office and sign the agreement we had reached,” he added.“That was a mistake because if we had not gone out to eat and had signed at the same time we reached the agreement, Ronaldo would have stayed at Barcelona.”“One of his agents went off for half an hour to take a phone call,” he commented.“At that time we did not pay much attention to the agent’s absence. When he came back he apologized, had some coffee and toasted before going to the office to sign the contract.”“From the first moment we got to the president [Josep] Nunez’s office, the agents began to put obstacles up, they told Ronaldo to go home and that they would call him to sign. I asked them if they did not want to sign,” Gaspart explained.“They insisted they did but what they wanted was to renegotiate almost the entire contract, increasing the financial terms. They were trying to destroy the talks.”
