Enceladus, a moon of Saturn smaller than the British isles (comparison image), has a region at the south pole that is less than 1,000 years old, and maybe only 10 years old. This conclusion, announced at Cassini science briefings in London August 30, is based on multi-instrument observations taken July 14 during the closest flyby ever of Enceladus (08/09/2005, 07/14/2005). Crystalline ice has been found in four 80-mile-long parallel canyons dubbed “tiger stripes” due to their appearance. Water ice has been observed venting into a plume of small particles from these cracks, which are noticeably warmer than the surrounding regions. Measurements from all the instruments aboard the Cassini spacecraft converge on the conclusion that Enceladus’ southern polar surface is young, probably active today. Two instruments detected icy particles coming from the south pole. The Ion and Neutral Mass Spectrometer (INMS) and the Cosmic Dust Analyzer (CDA) measurements reached a peak at closest approach (graph, flyby chart), showing that material is being emitted now, and probably accounts for at least some of the fresh material replenishing the E-ring around Saturn. The Magnetometer (MAG) confirmed the existence of this plume by watching its asymmetric influence on the magnetic field lines around Enceladus; the Ultraviolet Imaging Spectrometer (UVIS) arrived at the same conclusion. The Virtual and Infrared Mapping Spectrometer (VIMS) (picture) and Composite Infrared Spectrometer (CIRS, see article and picture) showed a temperature rise across the tiger-stripe cracks up to -279°F, almost 40° warmer than expected. Apparently this is warm enough to cause sublimation of ice from the surface. The crystalline nature of the ice constrains its age to 1000 years or less. Crystalline ice rapidly changes to an amorphous structure when exposed to solar radiation. Another odd thing about the tiger stripes is that each of them curves into a question mark shape at one end, all facing the same way (picture 1, picture 2). Could this be a rotational effect, or is it due to a massive flow from the west? The closest-approach image (picture and zoom-in movie) revealed boulders about 20m in size that New Scientist said could be ejecta from eruptions. That Enceladus should be erupting material today is puzzling to the planetary scientists for several reasons. For one, the north pole is heavily cratered and therefore looks much older; why would the south pole be active, when normally the equatorial regions are the warmest? (compare prediction vs. observation). Another puzzle is the comparison with Mimas, a moon of similar size. Mimas is heavily cratered with no activity, even though it was pummeled by a colossal impact at some time in the past and is subject to greater tidal stresses due to its proximity to Saturn. Finally, small bodies cool the fastest. A moon the size of Enceladus should long ago have lost all its internal heat and remained forever frozen solid. To account for the heat and resultant activity (03/04/2005), planetary geologists are constructing models combining radiogenic heat from a rocky interior and tidal heating from interactions with Saturn and other moons. So far, however, these energy sources seem to come up short by an order of magnitude or two (see New Scientist). This is a “marvelous puzzle,” said one scientist; another said that “Enceladus is constantly evolving and getting a makeover.” Enceladus joins a “short list of bodies in our solar system where scientists have found internal activity,” the press release said. That list includes Io (05/04/2004), Titan (06/09/2005, 05/18/2005, 04/08/2005), Triton (05/30/2002), Earth, and Venus (see “Earth’s Ugly Sister Can’t Get a Date,” 08/16/2004). Most other solid planets and moons exhibit surface features that, while not active today, appear young (06/05/2003 commentary). The Cassini team expected that Enceladus would prove one of the prima donnas of the Saturn system. It appears that she delivered a “stunning surprise” of a performance. Sources: JPL, Cassini press release, NASA Cassini page, New Scientist, BBC News, the Planetary Society, EurekAlert and the Cassini Imaging Team. The latter contains polar projection maps, a graph and flyby chart, and three models attempting to explain the heating process.Scientists love a good puzzle, and being surprised is fun; we can all share the excitement of a new and baffling phenomenon. But what none of them seems to be asking is the obvious question: how could this moon be anywhere near 4.6 billion years old? Look at the size of those canyons – 80 miles wide and 50 miles apart – they speak of large-scale processes at work, not just minor eruptions. This revelation is just the latest in a long string of discoveries that challenge the consensus view of the age of the solar system. For all the flash and color of the model diagrams, New Scientist says that tidal heating and internal radioactivity are not anywhere near sufficient to drive the activity. Why not consider the possibility that Enceladus – as well as the solar system that contains it – is young. Don’t miss the zoom-in movie; it is really cool. It puts the imaging capabilities of Cassini into perspective. The color mosaic is also a beautiful sight. Here are the tiger stripes up close.

Stepping up its campaign on the National Register of Citizens (NRC), the Congress on Sunday alleged that the Modi government had tried to delay the process by arguing before the Supreme Court that the NRC could lead to law-and-order issues.The Congress also demanded the resignation of Chief Minister Sarbananda Sonowal as the BJP tried to “mislead” the people of Assam.Congress spokesperson Pawan Khera told presspersons that on November 30, the Attorney-General argued before the top court that the publication of the NRC could lead to violence and create a law-and-order problem.“On November 30, 2017, the Supreme Court came down heavily on the Modi government for its excuses to delay the NRC in Assam. The Attorney-General gave the excuse of fear of violence,” Mr. Khera said and pointed out that the court reprimanded the government.“We do not see how the aforesaid situation can even remotely arise as we have already indicated in the earlier part of the present order that claims of 47 lakh persons (regarding whom the doubt pertained to parental linkage) and 29 lakh persons (married women who had submitted gram panchayat secretary certificates) are still pending and would be subject to verification and covered by publication of another draft NRC at a subsequent point of time,” Mr. Khera said quoting the SC.The Congress has stepped up its campaign after BJP president Amit Shah said in Parliament that it was the BJP government that had shown the “courage” to implement it.The Congress counter has been that the NRC update was the outcome of the 1985 Assam Accord, signed by the Rajiv Gandhi govenment, and was started by a Congress government in the State. On Monday, former Chief Minister Tarun Gogoi will be addressing a press conference in Delhi on the NRC issue.“The Shah of lies and the Shahenshah of Jumlas tried their best to stall NRC. I will tell you how they hatched a conspiracy to stop, delay and disrupt the NRC process,” Mr. Khera said.“We demand that the Modi government apologise to the people of Assam for attempting to stall the NRC … We also demand the resignation of the so-called Jan Nayak Shri Sarbanand Sonowal who has no right to be the Chief Minister of a State that his party so shamelessly cheated in the Supreme Court on the issue of NRC,” he said.
Ex-Chelsea keeper Schwarzer convinced by Mount potentialby Paul Vegas14 days agoSend to a friendShare the loveFormer Chelsea goalkeeper Mark Schwarzer is convinced by the potential of Mason Mount.Schwarzer has now backed the midfielder to continue his rise, and is keen to see how he interacts with his more experience team-mates during the rest of the season.”I think Mount has done really well so far,” Schwarzer told Goal.”He has been exciting to watch. He is a big talent, he played very well in the Championship last season under Frank [Lampard] so he knows him really well.”I like so much about him. The biggest thing is that movement, dropping the shoulder, taking on a player and caressing the ball.“His link-up play is very good. His understanding with Tammy Abraham is very good. I like his evolution.”It will be interesting to see what he is like when more experienced players come into the team like Willian and Pedro, if there’s more consistency and how he links up with them.” About the authorPaul VegasShare the loveHave your say

New Delhi: Filing an RTI to get information about policy decisions is not as easy as it seems. Sometimes, you may be behind the bars for seeking information about officials in the government.In a similar case that has come to the notice, an RTI activist Hemant Kumar has been sent to judicial custody in connection with SC/ST atrocities act case for seeking information regarding a top IPS officer in Bihar. Kumar, who dubbed the charges as fabricated, had also urged chief information commissioner (CIC), New Delhi to defer the scheduled video conferencing. The conferencing was scheduled for March 18 in regard to his query about MSc degree of the officer. As his case was heard on the scheduled date without his presence, Kumar was arrested on March 24, a few days after the hearing of his case by the CIC. Sources have claimed that Kumar was fighting against various irregularities and seeking information under the RTI including overstay of a regional rural bank’s employees at the same branch. Sources further claimed that Kumar’s query had led to the transfer of several bank employees, including a woman who had lodged a case against him with Mithanpura police station. On December 21, 2012, Muzaffarpur police was not only arrested him but paraded in the town with placards dangling on his chest and back saying he was a habitual eve-teaser. When produced before the chief judicial magistrate, he was granted bail. The then SHO Jitendra Prasad, who had forced Kumar to wear the placard, apologised in court following a show-cause notice against him. While talking to Millennium Post, Kumar’s advocate Sumit Kumar Suman said that one Ajay Kumar Paswan of Vaishali lodged an FIR against his client with SC/ST police station on March 12 on the charges of forgery.
How about a Big 4 in Miami instead of the championship trio of LeBron James, Dwyane Wade and Chris Bosh? Reports indicate as the Heat officials focus on winning a third straight NBA title, their thoughts linger on wooing the impending free agent and New York Knicks star forward.Sources told ESPN.com that Heat officials and the team’s leading players have already started to explore their options for creating sufficient financial flexibility to make an ambitious run at adding this summer in free agency.The mere concept would require the stars James, Wade and Bosh to all opt out of their current contracts by the end of the month and likely take further salary reductions in new deals that start next season to give Miami the ability to offer Anthony a representative first-year salary.The Heat also are prevented from making any formal contact with Anthony until July 1 and can do so then only if he opts out of the final year of his current contract. Anthony has until June 23 to notify the Knicks of his intentions, according to sources.With cooperation from their stars and role players Udonis Hslem and Chris Anderson, who also have player options for next season, the Heat could open up in excess of $50 million in cap space this summer and have the most financial flexibility in the league. The only Heat player locked into place for next season is Norris Cole at a salary of $2 million, although team president Pat Riley will have to contend with a handful of cap holds for pending free agents as well as their upcoming first-round pick (No. 26 overall) in the draft later this month.
Former Aston Villa manager Paul Lambert insists the high expectations surrounding the club is hindering its progress.Paul Lambert who also managed midlands rivals, Wolverhampton Wanderers as recent as the 2016-17 season, has suggested that managing Aston Villa is a difficult task due to the expectancy levels at the club.The Villans are currently spending their third campaign in the Sky Bet Championship and after a poor start to the season, former Brentford manager Dean Smith has been appointed as a replacement for Steve Bruce.Smith who will be joined by former Villa defender has been tasked with trying to earn the club a return to the Premier League but Lambert, who had a three-year spell at Villa between 2012 and 2015 feels that the new manager will come under immediate pressure.Lambert told Sky Sports News, as quoted by Sports Mole: Aston Villa explains why they spent so much money on players Manuel R. Medina – September 6, 2019 According to Aston Villa’s chief executive, the team needed to spend £144.5 million on 12 players in order to stay competitive.“It’s difficult because of the expectation level really. The club was trying to get sold [when I was there] but the fans have got the history of a European Cup-winning football club.“You’ve got that, a big fanbase behind you, who every time expect you to be up there.”Villa are currently placed 15th on the Championship standings.
