Credit: NASA/JPL-Caltech/UCLA/MPS/DLR/IDAIn the tens of thousands of photos returned by NASA’s Dawn spacecraft, the interior of Ceres isn’t visible. But scientists have powerful data to study Ceres’ inner structure: Dawn’s own motion.Since gravity dominates Dawn’s orbit at Ceres, scientists can measure variations in Ceres’ gravity by tracking subtle changes in the motion of the spacecraft. Using data from Dawn, scientists have mapped the variations in Ceres’ gravity for the first time in a new study in the journal Nature, which provides clues to the dwarf planet’s internal structure.“The new data suggest that Ceres has a weak interior, and that water and other light materials partially separated from rock during a heating phase early in its history,” said Ryan Park, the study’s lead author and the supervisor of the solar system dynamics group at NASA’s Jet Propulsion Laboratory, Pasadena, California.Ceres’ gravity field is measured by monitoring radio signals sent to Dawn, and then received back on Earth, by NASA’s Deep Space Network. This network is a collection of large antennas at three locations around the globe that communicate with interplanetary spacecraft. Using these signals, scientists can measure the spacecraft’s speed to a precision of 0.004 inches (0.1 millimeters) per second, and then calculate the details of the gravity field.Ceres has a special property called “hydrostatic equilibrium,” which was confirmed in this study. This means that Ceres’ interior is weak enough that its shape is governed by how it rotates. Scientists reached this conclusion by comparing Ceres’ gravity field to its shape. Ceres’ hydrostatic equilibrium is one reason why astronomers classified the body as a dwarf planet in 2006.The data indicate that Ceres is “differentiated,” which means that it has compositionally distinct layers at different depths, with the densest layer at the core. Scientists also have found that, as they suspected, Ceres is much less dense than Earth, the moon, giant asteroid Vesta (Dawn’s previous target) and other rocky bodies in our solar system. Additionally, Ceres has long been suspected to contain low-density materials such as water ice, which the study shows separated from the rocky material and rose to the outer layer along with other light materials.“We have found that the divisions between different layers are less pronounced inside Ceres than the moon and other planets in our solar system,” Park said. “Earth, with its metallic crust, semi-fluid mantle and outer crust, has a more clearly defined structure than Ceres,” Park said.Scientists also found that high-elevation areas on Ceres displace mass in the interior. This is analogous to how a boat floats on water: the amount of displaced water depends on the mass of the boat. Similarly, scientists conclude that Ceres’ weak mantle can be pushed aside by the mass of mountains and other high topography in the outermost layer as though the high-elevation areas “float” on the material below. This phenomenon has been observed on other planets, including Earth, but this study is the first to confirm it at Ceres.The internal density structure, based on the new gravity data, teaches scientists about what internal processes could have occurred during the early history of Ceres. By combining this new information with previous data from Dawn about Ceres’ surface composition, they can reconstruct that history: Water must have been mobile in the ancient subsurface, but the interior did not heat up to the temperatures at which silicates melt and a metallic core forms.“We know from previous Dawn studies that there must have been interactions between water and rock inside Ceres,” said Carol Raymond, a co-author and Dawn’s deputy principal investigator based at JPL. “That, combined with the new density structure, tells us that Ceres experienced a complex thermal history.”Dawn’s mission is managed by JPL for NASA’s Science Mission Directorate in Washington D.C. Dawn is a project of the directorate’s Discovery Program, managed by NASA’s Marshall Space Flight Center in Huntsville, Alabama. UCLA is responsible for overall Dawn mission science. Orbital ATK Inc., in Dulles, Virginia, designed and built the spacecraft. The German Aerospace Center, Max Planck Institute for Solar System Research, Italian Space Agency and Italian National Astrophysical Institute are international partners on the mission team.

OAS urges Haitian political leaders to redouble efforts on formation of a new government

first_img Share NewsRegional OAS urges Haitian political leaders to redouble efforts on formation of a new government by: – August 13, 2011 10 Views   no discussions Tweet Sharing is caring!center_img Share Share Secretary General of the Organization of American States (OAS), José Miguel InsulzaWASHINGTON, USA — The secretary general of the Organization of American States (OAS), José Miguel Insulza, has noted with serious concern the continuing difficulties in the approval and appointment of a new prime minister in Haiti, following the rejection of President Michel Martelly’s second nominee for this post by the Haitian Parliament.Insulza recognized the constitutional responsibility of Parliament in approving or not the president’s designee for the post of prime minister. He therefore called on the Haitian political leadership to redouble their efforts in finding a consensus that will allow for the formation of a new government at the earliest moment, noting that Haiti has been without a fully functioning government since Martelly’s inauguration on May 14, 2011.“Mindful of the urgency to continue with the reconstruction efforts (following the devastation caused by the January 10, 2010 earthquake in Haiti) and the crucial importance of consolidating and strengthening democracy in this OAS founding member state, a consensus needs to be found for the approval of a prime minister,” said the head of the hemispheric organization.Insulza further elaborated that a functioning government is critical for the people of Haiti in addressing the varied problems confronting the country at this time. Reiterating his appeal for the development of a national consensus/dialogue among all Haitians, the OAS head affirmed that Haiti’s international partners are desirous of continuing to support the delivery of much needed development assistance to the country.Caribbean News Nowlast_img read more

Dortmund want Emmanuel Dennis

first_imgRelatedPosts Arsenal, Leeds, Everton battle for €40m Dennis Reinier completes Dortmund loan switch Manchester United target Sancho says ‘happy’ at Dortmund Borussia Dortmund is reportedly one of five clubs to have made a formal enquiry for Club Brugge striker Emmanuel Dennis. Belgian newspaper Het Laatste Nieuws reported last month that Borussia Dortmund have been following the progress of Emmanuel Dennis. Now Eurosport France claim that the Black and Yellows are one of five clubs to have contacted Club Brugge regarding the availability of the 22-year-old versatile forward. Bundesliga clubs RB Leipzig, Bayer Leverkusen, Italian side Napoli and Premier League club Southampton are said to be the other clubs interested in signing the highly rated forward. The report adds that Borussia Dortmund have already begun formal discussions about a possible transfer for the Nigerian international. Dennis has been primarily used as a number nine by Club Brugge, but he is also comfortable playing on either wing. He has nine goals and two assists in 33 appearances in all competitions this season. His goals include a brace away to Real Madrid in the Champions League, and one against Manchester United in the Europa League. Dennis’ current deal with Club Brugge does not expire for another two years, but the report claims that he is expected to leave the Belgian side in the summer. Borussia Dortmund have been linked with a number of attacking players in recent months, as they look to prepare for the potential summer exit of Jadon Sancho. The Black and Yellows are also said to be tracking the progress of Valencia’s Ferran Torres and Gremio’s Everton Soares.Tags: Borussia DortmundClub BruggeEmmanuel DennisEurosport FranceHet Laatse Nieuwalast_img read more

ASA’s new guidelines set to protect problem gamblers

first_img Ministers expected to raise National Lottery age limit August 17, 2020 Share Share ASA monitoring sweep marks gambling as the worst underage advertising offender August 26, 2020 UK gambling adopts toughest online advertising code to protect underage audiences August 27, 2020 StumbleUpon Submit Related Articles UK advertising regulators CAP and BCAP are ready to roll out new standards, set to come into force on 1 April, which will change the ways in which gambling operators can promote their products. The new advertising standards will prevent the display of online adverts for gambling products and services that uses data on consumer online interests and browsing behaviour that may be targeted towards minors and those susceptible to gambling-related harm.In a letter sent to the former Minister for Sport Tourism and Heritage, Tracey Crouch, the Chief Executive of the Advertising Standards Agency (ASA), detailed: “From Q2, CAP will focus on protections for problem gamblers, people at risk of problem gambling and others who might be vulnerable to problem gambling behaviours.”The new strategy is primarily aimed at limiting the accessibility of gambling advertisements to minors, with plans to “extensively list unacceptable types of content, including certain types of animated characters, licensed characters from movies or TV and sportspeople and celebrities that are likely to be of particular appeal to children, and references to youth culture”.ASA’s guidelines will add to “existing guidance on the responsible targeting of ads, covering all media (including social networks and other online platforms)”, by also prohibiting the use of celebrity endorsement from those under the age of 25.The guidelines detail: “Gambling-like games or games that feature elements of simulated gambling activity are often popular with children and young people. “Such games should not be used to promote real money gambling products, for instance, by offering a trial version that plays a similar role to an advergame. Where social and online games feature marketing communications for gambling games, they should not be directed at under-18s.”“Gambling operators sometimes feature sports people or celebrities in marketing communications. This can often be through an endorsement agreement between the operator and the individual. Such individuals who are or appear to be under 25 are explicitly prohibited from appearing in gambling marketing communications by CAP Code rule 16.3.14 and BCAP Code rule 17.4.6.”last_img read more

Van Dijk lays foundation for Liverpool’s title finish

first_img– Tense title race –“It’s a rather positive moment. Most of the players will probably be better after the international break. For example, Joe,” Liverpool boss Jurgen Klopp said.“Joe is now running with 100 percent of his weight because we have different opportunities to run. It looks good.”Better yet, given the tense status of the title race with Manchester City — they trail the leaders by one point — Klopp could also welcome back central defender Dejan Lovren, out with a hamstring problem since an FA Cup defeat at Wolves in early January, for the visit of Burnley.“Dejan trained yesterday (Thursday) for the first time, completely normal,” Klopp said.“But we have to see. He was out for a while so we have to see his fitness. He’s not injured any more, he is fit but how fit we have to see.”Additional defensive options and cover will be welcome for Klopp although, as long as he has van Dijk at the centre of his defence, his team can be confident of maintaining their current impressive record at the back.Five consecutive clean sheets have kept Liverpool in contention in the Premier League, with West Ham’s Michail Antonio the last player to score against Reds keeper Alisson Becker 512 minutes ago.The 27-year-old’s composure, distribution, tackling, heading and experience have all been hugely impressive at a time when other senior stars are struggling for top form.And should Klopp have serious aspirations to go one better than last season’s Champions League final defeat to Real Madrid, he will be hoping that van Dijk maintains such form when Liverpool visit Munich for the second leg of their last 16 tieShare on: WhatsApp FILE PHOTO: Virgil van DijkLiverpool, United Kingdom | AFP | Liverpool’s attacking power kick-started their challenge for a first English title in 29 years, but with the finish line in sight, the focus is on a rock-solid defence led by Virgil van Dijk as Burnley visit Anfield on Sunday.The arrival of Van Dijk in a £75 million ($97 million) transfer from Southampton was met with scepticism in some quarters 15 months ago, but the Dutch star’s imperious form quickly quietened such concerns.This season, in particular, the durable centre-half — Liverpool’s only outfield ever-present in the Premier League — has been particularly outstanding.His high-level displays have been crucial for Liverpool in recent weeks as his attacking team-mates have, by their previous standards, failed to hit the heights of months gone by.Watford were swept aside 5-0 at Anfield at the end of last month, but those goals were the only ones scored by Liverpool in a spell that has featured goalless draws with Bayern Munich, Manchester United and Everton.The Merseyside derby saw van Dijk in formidable form, an indication of his importance to the team as the forward line of Mohamed Salah, Sadio Mane and Roberto Firmino struggled for form.Van Dijk, 27, is a pivotal figure for Liverpool as they prepare for the Burnley fixture.Liverpool’s defence has struggled with injuries to key personnel, aside from van Dijk this season, with the loss of Joe Gomez, coincidentally against Burnley when his side won 3-1 at the start of December, a particular loss.The young England international had emerged as an important figure in Klopp’s back four prior to suffering a fractured leg, although the fact he returned to running in training on Thursday suggests he could be in contention for the meeting with Tottenham at the end of the month.last_img read more

Something Historic is Happening at Harlequin Productions

first_imgFacebook27Tweet0Pin0Submitted by Harlequin ProductionsSomething historic is happening at Harlequin Productions.Harlequin is preparing to stage the third musical of their 2017 season. The company has never produced three musicals in the same year. This special third musical is a commemoration of Harlequin’s 25th anniversary season.“We wanted to do something special to celebrate our silver anniversary,” said Harlequin Managing Artistic Director Scot Whitney. “There are plenty of big musical fans out there, and we thought we’d give them a treat.”Harlequin Productions’ Little Shop of Horrors was such a hit that it was held over for an additional week of shows. Photo courtesy: Harlequin ProductionsFollowing The Stardust Christmas Dazzle and Little Shop of Horrors, the third musical of the season is the Last Five Years, running August 18-September 10.This musical features just two actors and tells the story of the rise and fall of a five-year relationship between Jamie and Cathy, played by musical theater veterans Aaron Lamb and Katherine Strohmaier. The two take turns singing songs, telling the story from their point of view. However, Jamie begins his story at the beginning of the relationship and each song moves him forward in time, while Cathy begins at the end of the relationship and each song moves her backward in time. This unique storytelling technique adds great nuance to the story, all backed by a breathtaking musical score by multi Tony-award winning composer Jason Robert Brown. The result is a powerful story of love and loss and a poignant examination of modern-day relationships.Musical productions have always been a favorite at Harlequin Productions. Photo courtesy: Harlequin Productions.“It’s a profound story that is relatable for anyone who has felt their heart soar with love only to break with loss,” said the show’s Director Linda Whitney. “It celebrates the highest heights of love while acknowledging the lowest lows.”Harlequin’s presentation of this musical will be especially unique. As Linda Whitney explains, “When one of the actors is singing their song, the other will be accompanying them on piano. So the two characters remain engaged through the music even when only one is singing.”Musical fans can enjoy a bonus musical and celebrate Harlequin’s 25th anniversary by grabbing their tickets to The Last Five Years at harlequinproductions.org.last_img read more
