Planet Habitable Zone Cannot Be Too Windy

first_imgThe “habitable zone” of a planet usually concerns its distance from the star such that it can support liquid water.  But what if the star fries the surface with intense stellar winds?“Deadly stellar winds could put a stop to life” reads the headline of an article on Astrobiology Magazine.  Planet Earth has a protective magnetic field that shields its inhabitants from the solar wind.  But the solar wind emitted by our star is mild compared to the intense storms of charged particles flung out by other stars.Joe Llama from the University of St. Andrews looked at the winds that bombard one of the “hot Jupiters” (giant planets orbiting close to parent stars), named HD 189733.  He considered what such a wind would do to an earth-like planet, even if it orbited in its habitable zone:In the case of HD 189733b, this is not a huge problem as it and other hot Jupiters are already far too hostile for life to survive. But strong stellar winds could also strip away the atmospheres of potentially habitable planets further out, something that would have dire consequences for their habitability.  Joe comments: “Imagine what the Earth would be like with its air stripped away, placed in a radiation bath. There could be numerous planets like this that in many ways resemble our world, but where life never stood a chance.”The article did not quantify how many stars would irradiate their planets to death, but Llama thinks they “could be numerous”.  There would be no point looking for life on planets in such systems.  “For more than two decades we have been stepping up the search for other planets like the Earth,” he said.  “Our new work will help refine this quest, enabling us to rule out the sites where dangerous activity on stars would kill off life from the start.”Earlier this month on Astrobiology Magazine, Sara Seager of MIT presented a “revised” Drake Equation that leaves off Frank Drake’s final factors about intelligent life evolving.  She’s just interested in any kind of life emerging on a habitable planet.  Llama’s conclusions will surely affect one factor she calls FQ, the fraction of stars that are quiet.  “Some stars are like our solar maximum all the time, with flares and other activity,” Seager said. “We don’t like those noisy stars.”The “habitable zone” theory is is a classic case of dogmatic slumbers being jolted awake by physical reality.  In Carl Sagan’s Cosmos days, it seemed so simple: billions upon billions of stars might have life, based on the idea that all you needed was a rocky planet at the right distance from its star.  Over the past decade we have been adding complications to the “habitable zone” idea, narrowing down substantially the probability of finding those lucky stars.  Last year about this time, our list of factors (reported from astrobiology literature) was at nine (see 9/08/12); we predicted additional factors would be thought of.  Now we have #10: the Stellar Wind Habitable Zone.  Earth continues to look mighty special in this vast universe.  You can thank your lucky stars if your world view requires heavy doses of superstition.  Others of us find positive evidence for intelligent design.

Supercalifragilisticexpialidocious Old Mary Poppins book returns to library

first_imgST. PAUL, Alta. – It was a supercalifragilisticexpialidocious find.A first-edition hardcover book of “Mary Poppins,” published in 1934, is back in an Alberta public library after 40 years.Dwayne Olson with the library in St. Paul, a town northeast of Edmonton, says the book was taken off the shelves in 1978 and replaced with newer versions.The copy was recently donated back to the library after being discovered at a local thrift store.“I was surprised,” says Olson. “It’s in pretty good shape.”The book was the first of eight in a series by P.L. Travers about a magical, umbrella-toting nanny that spawned a Disney movie and stage musicals.Olson says the library’s copy is a bit faded. And it’s spine needs to be fixed.He’s not sure how much it’s worth, but it’s not for sale.“To have this book in our library, I mean, it’s priceless,” says Olson, “especially for people to look at and see it and kind of go, ‘Oh, that’s cool.’”The book is being displayed in a locked glass cabinet with other old texts.People can ask to see the book, but they won’t be allowed to check it out.“It doesn’t leave the library,” says Olson.last_img read more

Nunavut premier ousted after recall vote in legislature

first_imgKent DriscollAPTN NewsPaul Quassa has been voted out as premier of Nunavut during a recall motion Thursday.Under Nunavut’s consensus government system, regular members can remove a premier with a majority vote.Now that Quassa is out, the Members of the legislative assembly will meet later Thursday afternoon to discuss the next steps.Given Nunavut is not allowed to be without a premier, a leadership forum is likely to follow soon.While previous premiers in Nunavut have faced similar leadership reviews part way through their term, this is the first time a recall vote has been debated in the territory’s assembly.It is also the earliest a premier has faced such a challenge – Quassa only took office in November 2017.Quassa’s government has faced questions on spending throughout this term, the highest profile one being the Northern Lights Trade Show spending.The Nunavut Government spent $570,000 to send 73 staff and officials to the bi-annual trade show in Ottawa.Part of that tab was a $7,000 car service to shuttle the Premier around Ottawa.Regular members, the de facto opposition under Nunavut’s consensus system of no political parties, have questioned the spending.Quassa defended the expense in the assembly, saying “you have to spend money to make money” and calling the meetings in Ottawa important for the government to establish relationships and pursue funding.He defended the car service by pointing out that in order to access Parliament Hill by car, you need a service with a level of security clearance.Another spending issue has been front and center in this recent assembly sitting, this one about money not spent.The current government pulled funding for a proposed road connecting Grays Bay, Nunavut to an existing mining road in the Northwest Territories.While initially claiming that the federal government denied funding first, it has come out in the assembly that the Nunavut government was the first to reverse course on the 227 km all season road.The project had moved ahead under Peter Taptuna’s time as premier, but died under Quassa’s.Taptuna is from the Kitikmeot region in western Nunavut where the road would be created.Quassa is from Baffin Island in the east, and western MLAs have become frustrated with what they perceive as the abandonment of a vital economic driver for the region.Finance Minister Joe Savikataaq defended the decision as the new government sticking to its priorities, saying in the Assembly, “all our money comes from one pot. If we spend here, we have none for there.”The motion to remove was made Tuesday morning by Arviat MLA John Main, on behalf of the Regular Member’s Caucus. There are 13 members of that caucus, and only 8 members of the cabinet including Premier Quassa.While those numbers may be daunting to Quassa, Nunavut politicians have a history of letting them continue.Nunavut’s three previous premiers, Paul Okalik, Eva Aariak and Peter Taptuna, have all faced leadership reviews at the request of the assembly.All three held on as premier.The difference, in this case, is that those reviews were held halfway through their term as a legislated part of the consensus system.This review is unique as it is the earliest and the first ever presented as a recall vote.If successful on Thursday, the vote would trigger an immediate leadership forum where a new premier would be chosen.last_img read more

Tyson Foods New facility in Tennessee to create 1500 jobs

first_imgHUMBOLDT, Tenn. – Tyson Foods Inc. plans to build a new chicken production complex in Tennessee, a $300 million project that is expected to create more than 1,500 jobs when the facility begins operations in late 2019, the company said Monday.The new plant in Humboldt will produce pre-packaged trays of fresh chicken for retail grocery stores nationwide, the Springdale, Arkansas-based company said in a statement and a news conference. The plant will help it meet strong consumer demand for its chicken, the company said. Construction is expected to begin within three to six months.Tennessee Gov. Bill Haslam and U.S. Sen. Bob Corker attended the news conference and praised Tyson for choosing Humboldt, a rural city of about 8,200 people located about 85 miles (135 kilometres) northeast of Memphis. Tennessee competed with other states for the project. Doug Ramsey, group president of poultry for Tyson, would not discuss which other states were in the mix.Officials said the local agriculture community will benefit from the project, providing supplies and feed for the plant, which will feature a hatchery, processing facility and feed mill. Tyson’s project will be built at a 500-acre (200-hectare) Gibson County industrial park that’s been seeking a tenant for about 20 years, county mayor Tom Witherspoon said.“It’s rare that you get a manufacturing project that has such an impact on our agriculture community,” Witherspoon said. “That’s what’s made it such a good project for Gibson County.”Ramsey said the existing industrial park, availability of labour and access to feed grains produced in the region, were reasons why Tyson chose Gibson CountyHaslam said that while unemployment in Tennessee is low — at 3 per cent as of September — “it’s no news that some of our rural counties have struggled.” He called the plant a “big deal” for the state.“Agriculture is a big part of who we are,” Haslam said. “So we combine our farmers’ ability to contribute to this facility with the jobs that will be located here.”Tyson currently operates four facilities in the state, employing about 5,000 people. The company says it paid Tennessee farmers more than $61 million in the 2016 fiscal year.The announcement marks the second major economic development project Tyson has begun this year in Tennessee. In August, the company announced an $84 million expansion of operations in Union City. That project is expected to create about 300 jobs.The company’s portfolio of products includes Tyson chicken, Jimmy Dean, Hillshire Farm and Ball Park.last_img read more

Saudi Aramco in parleys with Reliance for stake in refinerypetchem complex

first_imgNew Delhi: Saudi Aramco, the world’s largest oil exporter, is in talks to buy stake in Reliance Industries’ oil refineries and petrochemical complex, sources privy to the development said. Aramco opened talks with Reliance as $44-billion mega refinery-cum-petrochemical complex, where it was taking a 50 per cent stake along with UAE’s ADNOC, got delayed after ruling BJP-government scrapped plans to acquiring land for the project in coastal Maharashtra. Also Read – Thermal coal import may surpass 200 MT this fiscalThe sources said talks have been going on for few months now but there is nothing concrete that has materialised just as yet. Reports suggested Aramco may take 25 per cent stake for $10-15 billion but sources discounted such a valuation saying market capitalisation of Reliance at Tuesday’s closing price on BSE was over Rs 8.5 lakh crore, at least half of which or Rs 4.25 lakh crore (about $60 billion) would be coming from refinery and petrochemical business. A 25 per cent stake would translate into $15 billion without even considering any premium of giving a firm a foothold into a well-established business in the world’s third largest energy consuming nation, they said.last_img read more
