Saturn, the Bringer of Youth

first_imgMore discoveries of youthful phenomena contradict Gustav Holst’s musical tribute to “Saturn, the Bringer of Old Age.”Recent analyses of Cassini data continue the theme of Saturn’s music, which is more like Peter Pan than Holst. As you interpret the following news stories, keep in mind that the moyboy ages are upper limits. They could be much lower. What surprises planetary scientists is that these phenomena exist at a time when humans can observe them. If they were billions of years old, how could that be?Saturn and its rings as seen by Cassini, April 25, 2016.Young RingsSaturn’s Rings Are Beautiful, But They Won’t Last (Space.com). “But if you could travel 300 million years into the future, you would need to, because by then, chances are those rings would be gone — and they could disappear even faster.”Saturn Is Losing Its Rings (Live Science). “We are lucky to be around to see Saturn’s ring system, which appears to be in the middle of its lifetime,” lead author James O’Donoghue. Ring rain is only one drain on Saturn’s rings, reports Meghan Bartels. The scientists measured such a high rate of loss, it implies the rings are losing “a huge amount of the icy rings, between 925 and 6,000 lbs. (420 to 2,800 kilograms) every second.” But there’s more:The fate of the rings looks even grimmer considering research published earlier this year using Cassini data, which looked at a different, still-more-voluminous, type of infall from Saturn’s rings that’s descending into the planet. O’Donoghue and his co-authors didn’t include that infall in the estimates presented in their paper, but suggested in an accompanying statement that the two phenomena combined could gorge through the rings in more like 100 million years.Saturn is losing its rings at ‘worst-case-scenario’ rate (Science Daily and NASA Astrobiology Magazine). Particles are being drawn into Saturn hourly in a process called “ring rain.” Looking back over time, the scientists give the rings a maximum age of 100 million years – just 1/45th the assumed age of Saturn. What happened so that we see them in the human era of telescopes? See the problem discussed in video clips from NASA Goddard Spaceflight Center. After explaining ring rain, the narrator puts an upper limit on age of 100 million years for the rings. He says, “This means Saturn wasn’t born this way, as the planet is known to be over 4 billion years old.” But is that really known? Nobody was there to measure it. Believing in 4 billion years creates a conundrum of explaining how Saturn got its rings so recently. These are incompatible beliefs.“We estimate that this ‘ring rain’ drains an amount of water products that could fill an Olympic-sized swimming pool from Saturn’s rings in half an hour,” said James O’Donoghue of NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “From this alone, the entire ring system will be gone in 300 million years, but add to this the Cassini-spacecraft measured ring-material detected falling into Saturn’s equator, and the rings have less than 100 million years to live.This is relatively short, compared to Saturn’s age of over 4 billion years.” O’Donoghue is lead author of a study on Saturn’s ring rain appearing in Icarus December 17.A recent origin for Saturn’s rings from the collisional disruption of an icy moon (Icarus). The latest attempt to solve the ring age problem comes from John Dubinski. In this paper, he calls on the planetologist’s favorite tool – an impact – to get the rings to form just when humans can see them. Simultaneously, it solves the heat problem for Enceladus. Convenient for him, there is no way to prove it, because the Mimas-size impactor was never observed.Dione, Tethys, Pandora and Saturn’s rings from Cassini, Sept 22, 2005Young MoonsEnceladus is mentioned in the above articles as another body constantly losing material to Saturn. “The team also discovered a glowing band at a higher latitude in the southern hemisphere,” NASA Goddard says. “This is where Saturn’s magnetic field intersects the orbit of Enceladus, a geologically active moon that is shooting geysers of water ice into space, indicating that some of those particles are raining onto Saturn as well.” From there, the article sidesteps the problem of Enceladus’ age, preferring a hydrobioscopic dodge about possible life on Enceladus.Long-term stability of Enceladus’ uneven ice shell (Icarus). This paper by European planetologists tries to keep Enceladus old, despite those hundred-some-odd geysers blasting material out to space every hour, creating the E-ring around Saturn and losing some of that ice to Saturn itself. They invent a model that keeps the ice shell in a steady state, but that doesn’t explain why heat flow up to 60 watts per square meter is coming out of that little bitty moon, the diameter of Arizona or Iowa (not that those states are little bitty, but that’s small for a solar system object).Implications of nonsynchronous rotation on the deformational history and ice shell properties in the south polar terrain of Enceladus (Icarus). One of the conclusions of this paper is that “Enceladus’s tiger stripes are on the order of 100,000 years old.” That’s a wildly young age for standard views of the age of the solar system. Why did it happen that recently instead of billions of years ago?Artwork of the Cassini spacecraft flying through the geyser plumes of Enceladus.Orbital evolution of Saturn’s mid-sized moons and the tidal heating of Enceladus (Icarus). Here’s another attempt to keep Enceladus old, this time by Japanese scientists using N-body simulations. Right off the bat, though, they identify two problems: tidal forces that should pull the inner moons into Saturn over time, and the Enceladus geysers that shouldn’t be there. Tidal heating, they say, is “orders of magnitude” too low to keep that small moon’s inferred ocean liquid. Their simulations “may” explain how these problems could be surmounted, but their model falls far short of proof. In the end, they call for ‘future study” of the possibilities.The formation and orbital evolution of Saturn’s inner mid-sized moons – Rhea, Dione, Tethys, Enceladus, and Mimas – are still debated. The most puzzling aspects are 1) how the Tethys–Dione pair and the Mimas–Enceladus pair passed through their strong 3:2 mean-motion resonances during the tidal orbital evolution, and 2) the current strong heat flow from Enceladus, which is a few orders of magnitude higher than the tidal energy dissipation caused by the present orbital eccentricity of Enceladus.Saturn’s moon Dione Covered by Mysterious Stripes (NASA Astrobiology Magazine). Parallel lines and intersecting lines on the surface of Dione are “unlike anything else we’ve seen in the Solar System,” says one planetary scientist. The material making the lines, dubbed “linear virgae,’ could be coming “from Saturn’s rings, passing comets, or co-orbital moons Helene and Polydeuces.” Ignore the astrobiological speculation inserted without justification. Whatever the stripes are, “they are among the youngest surfaces on Dione” says Alex Patthoff, co-author of a paper on Geophysical Research Letters. The paper says, “Here we seek to constrain whether the linear virgae are endogenic, suggesting that the surface of Dione has been geologically active recently or if they are exogenic, suggesting a recent, or even ongoing, process in the Saturn system.” They argue for the latter, but either way, they’re young.Next Young Object?Looking ahead, the New Horizons spacecraft that found Pluto looking much younger than expected (16 July 2018) is due to reach its next target, Ultima Thule, on New Year’s Day (BBC News). The 30-km-wide object will be the most distant body in our solar system seen up close. Any bets on how young this object will appear?They’re still not taking our proposed compromise. We’ll give them 100 million years, if they accept that as the age of the solar system. No takers? Strange. Must be because that is not nearly enough time for Darwinism on Earth.I’ve been following the ring problem for many years. I wrote my first paper about it in a solar system astrophysics class back in December 1989, 29 years ago this month. I read each article about it by ringmasters Jeff Cuzzi, Larry Esposito, Carolyn Porco and others in Sky and Telescope and Astronomy magazines. When the internet made scientific papers accessible, I followed the current thinking each year. At JPL I got to meet some of the ringmasters and hear their talks. They knew of all the erosional processes since Voyager days, but kept hoping a mechanism would be found to keep the rings old. Nothing worked. As a member of the Cassini team, I followed the new discoveries about ring age. Now, we see that the erosion is faster than earlier thought. The evidence is now unquestionable: the rings are young. These articles didn’t even mention micrometeoroid bombardment, sputtering, collisional spreading and other processes that should destroy the rings in short order.Are you seeing a trend in the solar system? Everything seems to be “younger than thought.” In biology, complex organisms and traits keep appearing “earlier than thought.” Both trends bring bad news to old-age Darwinian materialists.

Fatalities at South Africa’s mines drop

first_imgThe South African mining industry has reported a significant drop in the number of fatalities and injuries on mines, although official numbers from the Department of Mineral Resources are only expected at the end of the month or early next month.Zero harm is the target, with the industry’s mantra: “Every worker returning from work unharmed every day.” The unofficial number of fatalities in 2014 had been placed at a record low of 84, the industry reported last week. It was expected that the official safety achievements would be about 9% better than the 93 fatalities reported in 2013, despite the industry adding more than 100 000 workers in the past decade to well over 500 000 now.Chamber of Mines’ safety and sustainable development acting head Dr Sizwe Phakathi told Mining Weekly Online that significant progress over the past few years.He said that 2014 was the seventh consecutive year of a drop in the number fatalities. In 2013, the industry made history when it reported less than 100 mining deaths for the first time. As at November 2014, 80 fatalities were officially reported.In the past decade, fatalities have been cut, safety has been improved, exposure to dust and noise reduced, tuberculosis (TB) infection rates reduced, more effective TB/HIV infection control and treatment programmes have been implemented, and best practice to improve health and safety outcomes has been adopted, according to the Chamber of Mines.Fatalities on mines had been cut from 615 in 1993 to 270 in 2003, and to 93 in 2013, said David Msiza, the chairman of the Mine Health and Safety Council (MHSC) and the chief inspector of mines. “It was noted that 2014 achievements are an improvement from 2013 by 8%, but [are] 85% better than 1993.”“The sector also saw a reduction of cases of noise induced hearing loss from more than 6 000 in 2003 to around 1 200 in 2013. TB rates in the gold sector have also halved.”At the Mine Health and Safety Summit in November 2014, the council said it would launch a centre of excellence in April. It will lead industry efforts to promote innovation through research and training of mine workers. The centre will go beyond health and safety to align with the National Development Plan. “We need to reclaim our space as a country that leads in mining innovation and excellence,” Mike Teke, president of the Chamber of Mines, said at the time.The centre is expected to undertake research; build capacity; facilitate research outcomes in areas such as rock engineering, human factors and occupational health and hygiene; and provide health and safety related training at all levels.Relationships with major international research centres and programmes will be built.The numbersCoal mines recorded a 93% safety improvement between 1993 and 2013, from 90 to seven fatalities, while the gold sector registered a 91% improvement from 436 fatalities in 1993 to 37 in 2013. The platinum sector had 29 fatalities in 1993 and 28 in 2013; this was down from a peak of 64 fatalities in 2004.Overall, fatality rates improved 72% to 0.09 in 2013 from 0.32 in 2003. Australia, Canada and the US recorded a combined improvement rate of 29% to a rate of 0.05 in 2013 from 0.07 in 2003, Mining Weekly Online reported.Injuries in South Africa fell from 8 515 in 1993 to 3 126 in 2013. In gold, injuries fell from 7 368 in 1993 to 1 252 in 2013; in coal, the drop was from 279 to 263 over the 20 years. In platinum, injuries went from 1 344 to 395.In the 11 months to November 2014, injuries decreased 25% from 2 799 in the comparative period the year before to 2 095.Harmony Gold had its first fatality-free quarter in the final quarter of 2014, while Lonmin had a calendar year without any deaths.SAinfo reporterlast_img read more

Suspended constable dies in custody

first_imgA Manipur Police constable, suspended in connection with the escape of an extremist leader, has allegedly died in custody during questioning.Constable S.M. Manjur Ahmed was one of 10 police and medical personnel suspended after Thokchom Nando Singh of the outlawed Kangleipak Communist Party escaped while undergoing treatment at the Jawaharlal Nehru Institute of Medical Sciences in Imphal on March 25.Singh was arrested more than a decade ago for the kidnapping and murder of Lungnila Elizabeth, the eight-year-old daughter of former Minister Francis Ngajokpa in November 2003. “The constable was found dead in custody,” a police officer said, adding that they were trying to ascertain the reason for his death.last_img read more

Spurious liquor claims 10 lives in U.P.

first_imgTen people died after consuming spurious liquor in Uttar Pradesh’s Barabanki district on Tuesday, a spokesperson for Ajay Sahani, Superintendent of Police, said.A dozen officials of the Excise and the Police Departments have been suspended for the incident, officials said.The tragedy was reported from the Raniganj area under the Ramnagar police station of the district.Excise Minister J.P. Singh said six deaths had been confirmed so far. In the Home Department briefing held in the evening, IG Law and Order Praveen Kumar put the figure at 10 and said four others were critical.Among the victims were four members of one family. Several others had been admitted to the trauma centre in Lucknow.The district Excise officer and the superintendent along with the local Inspector, an SI and two police constables have been suspended, while the suspension of the circle officer was under process, said Mr. Kumar.The victims purchased the liquor from a local registered shop run by one Danvir Singh. A case has been lodged against him and two associates. While a salesman has been arrested, Singh is absconding.Minister J.P. Singh said it was a “lapse” on the part of the local officials that spurious liquor was sold at a licensed shop. “Somewhere it is a lapse of our officials and staff because there is a standing order that stock in every shop must be checked,” he said.Chief Minister Yogi Adityanath instructed the Principal Secretary, Excise Department, to probe the incident and take strict action against the culprits. The CM has directed a three-member committee led by the Excise commissioner to submit a report within 48 hours.The team would probe the source of the liquor, the accountability of the local Excise, police officials and any “conspiracy” angle, said Chief Secretary Anup Chandra Pandey.Rajeev Krishna, ADG Lucknow, said they were investigating at what stage the liquor was adulterated, whether at the factory or at the store. The shop did not have the licence to sell open liquor or serve it like a bar but could only sell closed bottles, he said.Mr. Adityanath announced an ex-gratia of ₹2 lakh each to the kin of the dead.last_img read more

Satara MP demands re-election using ballot papers

first_imgNationalist Congress Party MP from Satara Udayanraje Bhosale on Monday voiced support for the ballot paper voting system as against the Electronic Voting Machine, which has been mired in controversy following multiple allegations of rigging. Mr. Bhosale’s statement comes days after Vanchit Bahujan Aghadi president Prakash Ambedkar announced he would be taking the issue to court. Saying that the EVM process was ‘manipulative’, Mr. Bhosale said that a difference of 672 votes was observed between the votes cast and votes counted in constituencies like Wai, Koregaon, Karad, Patan and Satara. “The statistics are there for everyone to see. It is clear that something was wrong with the entire election process. I don’t know why they call the EVMs fool-proof,” Mr. Bhosale said. While he accepted that securing fewer seats than expected in the recent Lok Sabha elections is a factor behind the issue of EVMs being raised, he also added that the difference between votes cast and votes counted still remains unexplained. Calling EVMs a “threat to India”, Mr. Bhosale demanded a re-election through ballot papers and also demanded that the EVM system be abolished permanently. “I challenge the Election Commission to see the results after re-elections are conducted using ballot papers. I am not going to rebel nor I am going to approach the courts. I can speak for myself and I want the people to raise their voice as well to save the future of India.” he said.On Saturday last week, Mr. Ambedkar, in a press conference in Dadar, had declared that his party would be taking up the issue of EVMs with the Election Commission of India and would also be filing petitions in regional high courts over the matter.last_img read more

CWG scam: Suresh Kalmadi denied bail

first_imgSacked Commonwealth Games Organising Committee chief Suresh Kalmadi will continue to stay in Tihar Jail as a Delhi court on Monday rejected his bail application in connection with the CWG corruption case.  The Patiala House court has held that Kalmadi might be able to influence witnesses since most of them (witnesses) have worked in OC under Kalmadi. Kalmadi had been arrested on April 25 for his alleged role in awarding a Games contract to a Swiss firm at an exorbitant rate.  Special CBI Judge Talwant Singh dismissed Kalmadi’s bail plea along with that of Games organising panel’s Joint Director-General (Sports) A.S.V. Prasad, saying that “the offences are of serious nature”. The court also said that “Prasad was close to Kalmadi” and had a key role in awarding the contract which caused huge loss to the exchequer. Kalmadi was arrested along with Prasad and three others for awarding the contract for installing the Time-Scoring-Result (TSR) system to a Swiss firm, Swiss Times Omega, at an exorbitant cost of Rs 141 crore, causing a loss of over Rs 95 crore to the public exchequer. – With inputs from PTIlast_img read more

Wait — no, I’m not. As much as I respect the original intent of the holiday (which became official back in 1894), to most of us, it’s just a bonus day off — one that’s blissfully tacked onto a weekend. So, yeah, stores; go ahead, run your sales. I’m listening.
