Although the lander did not achieve its core mission of a soft moon landing, it was still marked with a number of important firsts. Beresheet was the first private spacecraft to insert itself into lunar orbit and made Israel the seventh nation to achieve such a feat.The robotic explorers we send to new frontiers have a history of providing us with final images of other worlds before going gently (or violently) into the good night.

US president Donald Trump and North Korean leader Kim Jong Un walk after lunch at the Capella Hotel on Sentosa island in Singapore on 12 June 2018. Photo: ReutersPresident Donald Trump and North Korea’s Kim Jong Un concluded an extraordinary summit Tuesday with lofty promises by the American president to take care of a “very dangerous problem” and Kim forecasting “major change for the world.” They signed a document that Trump described as “pretty comprehensive,” but he declined to describe it, saying the details would be revealed later.The document signing followed a series of meetings at a luxury Singapore resort.Meeting with staged ceremony on a Singapore island, Trump and Kim came together for a summit that seemed just unthinkable months ago, clasping hands in front of a row of alternating US and North Korean flags, holding a one-on-one meeting, additional talks with advisers and a working lunch.Throughout the summit that could chart the course for historic peace or raise the specter of a growing nuclear threat, both leaders expressed optimism. Kim called the sit-down a “good prelude for peace” and Trump pledged that “working together we will get it taken care of.”In advance of their private session, Trump predicted “tremendous success” while Kim said through an interpreter that “we have come here after overcoming” obstacles.Aware that the eyes of the world were on a moment many people never expected to see, Kim said many of those watching would think it was a scene from a “science fiction movie.”In the run-up to the meeting, Trump had predicted the two men might strike a nuclear deal or forge a formal end to the Korean War in the course of a single meeting or over several days. But in the hours before the summit, the White House unexpectedly announced Trump would depart Singapore earlier than expected – Tuesday evening – raising questions about whether his aspirations for an ambitious outcome had been scaled back.Giving voice to the anticipation felt around the world, South Korean President Moon Jae-in said Tuesday he “hardly slept” before the summit. Moon and other officials watched the live broadcast of the summit before a South Korean Cabinet meeting in his presidential officeThe meeting was the first between a sitting US president and a North Korean leader.After meeting privately and with aides, Trump and Kim moved into the luncheon at a long flower-bedecked table. As they entered, Trump injected some levity to the day’s extraordinary events, saying: “Getting a good picture everybody? So we look nice and handsome and thin? Perfect.”Then they dined on beef short rib confit along with sweet and sour crispy pork.And as they emerged from the meal for a brief stroll together, Trump appeared to delight in showing his North Korean counterpart the interior of “The Beast,” the famed US presidential limousine known for its high-tech fortifications.Critics of the summit leapt at the leaders’ handshake and the moonlight stroll Kim took Monday night along the glittering Singapore waterfront, saying it was further evidence that Trump was helping legitimize Kim on the world stage as an equal of the US president. Kim has been accused of horrific rights abuses against his people.Trump responded to such commentary on Twitter, saying: “The fact that I am having a meeting is a major loss for the US, say the haters & losers.” But he added “our hostages” are back home and testing, research and launches have stopped.Trump also tweeted: “Meetings between staffs and representatives are going well and quickly … but in the end, that doesn’t matter. We will all know soon whether or not a real deal, unlike those of the past, can happen!”The summit capped a dizzying few days of foreign policy activity for Trump, who shocked US allies over the weekend by using a meeting in Canada of the Group of Seven industrialized economies to alienate America’s closest friends in the West. Lashing out over trade practices, Trump lobbed insults at his G-7 host, Canadian Prime Minister Justin Trudeau. Trump left that summit early and, as he flew to Singapore, tweeted that he was yanking the US out of the group’s traditional closing statement.The optimistic summit was a remarkable change in dynamics from less than a year ago, when Trump was threatening “fire and fury” against Kim, who in turn scorned the American president as a “mentally deranged US dotard.” Beyond the impact on both leaders’ political fortunes, the summit could shape the fate of countless people – the citizens of impoverished North Korea, the tens of millions living in the shadow of the North’s nuclear threat, and millions more worldwide.Alluding to the North’s concerns that giving up its nuclear weapons could surrender its primary deterrent to forced regime change, Secretary of State Mike Pompeo told reporters that the US was prepared to take action to provide North Korea with “sufficient certainty” that denuclearization “is not something that ends badly for them.”He would not say whether that included the possibility of withdrawing US troops from the Korean Peninsula, but said the US was “prepared to take what will be security assurances that are different, unique, than America’s been willing to provide previously.”The North has faced crippling diplomatic and economic sanctions as it has advanced development of its nuclear and ballistic missile programs. Pompeo held firm to Trump’s position that sanctions will remain in place until North Korea denuclearizes – and said they would even increase if diplomatic discussions did not progress positively.Experts believe the North is close to being able to target the entire US mainland with its nuclear-armed missiles, and while there’s deep skepticism that Kim will quickly give up those hard-won nukes, there’s also some hope that diplomacy can replace the animosity between the US and the North.
© 2017 Phys.org One of the types of pollutants emitted by cars and trucks is nitrogen oxides (NOx), in particular NO2 and nitric oxide (NO). These pollutants have been in the news in Europe over the past couple of decades because many truck and car owners have chosen to switch to vehicles powered by diesel fuel, which costs less than gasoline—but such vehicles also emit more NOx. To combat air pollution, officials in Europe and the U.K have enacted emissions standards that have resulted in less NOx emitted into the atmosphere. But most such emissions have applied only to NO2, which has muddied the standards. Making things ever murkier—such standards have been based on the percentage of NO2 in total NOx emissions. This is because not only do vehicles emit NO2 directly, but NO turns into NO2 over time once released into the air. Now, it appears that the percentages that officials have been using to set their standards has been wrong.To get an accurate measurement of the true percentage of NO2 in the NOx being emitted by vehicles, the researchers analyzed data from roadside monitors across Europe. In looking at the data, they found that NO2 percentages had risen, as expected, during the period 1995 to 2010 (as people converted to diesel) but then as emissions regulations came into effect, the percentage of NO2 leveled off and has remained at those levels ever since. These levels, the researchers note, are roughly half of what is described by air quality policy, which suggests Europe may reach mandated levels sooner than thought. Gentner and Fulizi Xiong suggest the group’s finding could have also implications for developing nations as well because consumers there tend to buy used diesel vehicles from Europe. 5,000 ‘Dieselgate’ deaths in Europe per year: study Credit: CC0 Public Domain This document is subject to copyright.

(Phys.org)—A team of researchers at the University of York in the U.K. has found that the proportion of nitrogen dioxide (NO2) in nitrogen oxides in European traffic emissions is smaller than has been thought. In their paper published in the journal Nature Geoscience, the group describes analyzing data from roadside monitors over the course of many years and what they found by doing so. Drew Gentner and Fulizi Xiong with Yale University offer a News and Views perspective on the work done by the team in the same journal issue and suggest that the team’s findings could have implications for air pollution standards organizations in many more places than just Europe. Journal information: Nature Geoscience More information: Stuart K. Grange et al. Lower vehicular primary emissions of NO2 in Europe than assumed in policy projections, Nature Geoscience (2017). DOI: 10.1038/s41561-017-0009-0AbstractMany European countries do not meet legal air quality standards for ambient nitrogen dioxide (NO2) near roads; a problem that has been forecasted to persist to 2030. Although European air quality standards regulate NO2 concentrations, emissions standards for new vehicles instead set limits for NOx —the combination of nitric oxide (NO) and NO2. From around 1990 onwards, the total emissions of NOx declined significantly in Europe, but roadside concentrations of NO2—a regulated species—declined much less than expected. This discrepancy has been attributed largely to the increasing usage of diesel vehicles in Europe and more directly emitted tailpipe NO2. Here we apply a data-filtering technique to 130 million hourly measurements of NOx , NO2 and ozone (O3) from roadside monitoring stations across 61 urban areas in Europe over the period 1990–2015 to estimate the continent-wide trends of directly emitted NO2. We find that the ratio of NO2 to NOx emissions increased from 1995 to around 2010 but has since stabilized at a level that is substantially lower than is assumed in some key emissions inventories. The proportion of NO x now being emitted directly from road transport as NO2 is up to a factor of two smaller than the estimates used in policy projections. We therefore conclude that there may be a faster attainment of roadside NO2 air quality standards across Europe than is currently expected.

Citation: Warped diffusive radio halo detected around the galaxy NGC 4565 (2019, July 23) retrieved 18 August 2019 from https://phys.org/news/2019-07-warped-diffusive-radio-halo-galaxy.html Using the LOw-Frequency ARray (LOFAR), astronomers have discovered a diffuse radio halo around the spiral galaxy NGC 4565. The finding, reported in a paper published July 16 on the arXiv pre-print server, could shed more light on the nature of NGC 4565, disclosing important insights about star-forming activity and the distribution of cosmic-ray electrons in this galaxy. Radio haloes are commonly observed around late-type spiral galaxies seen in an edge-on orientation. Studies show that the emission in radio halos is dominated by the non-thermal radio continuum component, indicative of cosmic ray electrons (CRe) and magnetic fields.Very little is known about the transport of cosmic rays in galaxies other than Milky Way. Low-frequency radio continuum observations have the potential to change this. They allow to investigate the oldest CRe far away from star formation sites in the halos of galaxies.So a team of astronomers led by Volker Heesen of University of Hamburg in Germany used LOFAR to conduct deep, low-frequency (144 MHz) observations of NGC 4565. Located about 38.8 million light years away, the target is a late-type spiral galaxy at an almost edge-on orientation. It is a quiescent galaxy with a low star-formation rate and an average mass surface density.”We have observed the nearby edge-on spiral galaxy NGC 4565 with LOFAR at 144 MHz in the radio continuum to measure the distribution of CRe and magnetic fields,” the astronomers wrote in the paper.During the observations, the astronomers detected a warp in the radio continuum of NGC 4565 that is reminiscent of a neutral hydrogen line (HI) warp and identifying a slight flaring of the galaxy’s radio halo. The researchers assume that this flaring is caused by the warp as the vertical intensity profiles are asymmetric, which is in agreement with the warp. According to the study, a minimum age for the warp was estimated at approximately 130 million years. This is the spectral age of the galaxy’s CRe, during which they are transported into the warp.Taking into account the results, the astronomers concluded that the NGC 4565 may be in the aftermath of a period with more intense star formation. They added that the galaxy has a relatively old population of CRe that has slowly diffused away from the star-forming disc.”The weak outflow that may be seen at higher frequencies was therefore probably stronger in the past, which explains the diffusive low-frequency radio halo,” the scientists wrote.Emphasizing that NGC 4565 could be in transition from an outflow- to an inflow-dominated phase, the researchers noted that this could explain why it behaves differently to NGC 7462, the only other galaxy in which they have detected a diffuse radio halo. They added that their research proves the significance of LOFAR observations for improving the understanding of cosmic rays and galaxy evolution.

The solo exhibition titled We are made of stars by Sabya Sachi Ghosh depicts the primordial nature of creation and a creative pictorial depiction of the universe. This exhibition that kicks off today is inspired by the resplendent starry sky on a moonless night. The theme of time travel is also touched upon. The works tries to bring about a feeling of an unbroken connection with time, since the moment of creation till out present state of its realisation. Also Read – ‘Playing Jojo was emotionally exhausting’ We are all made of stardust. This statement is very poetic and has a tinge of a primordial nostalgia attached to this feeling. The search for the reasons behind our creation ultimately takes us to the very beginning of time. Rational explanations are then replaced with metaphysical definitions that aim to quench our longing to know the truth behind the creation of our universe. Religion in its own narrow way tries to convey a meaning that is very self oriented in a karmic manner. Also Read – Leslie doing new comedy special with NetflixThe artist quotes, “When I gaze at stars twinkling in the night sky, I grasp the vastness of space and conceive of time as if it were matter and very tangible. My mind moves forward and backwards and is logical enough to haggle with a vegetable vendor. I am here stuck with this question; when we are capable of great thoughts why do we indulge in narrow selfish pursuits? Perhaps these ‘narrow selfish pursuits’ are our ways of preserving and continuing the progress of our species. I am not certain but for the lack of better ways we are as we appear to be.”When: January 23 to 29 Where: Open palm court Gallery, India Habitat Centre Timing: 10 am – 8 pm

The maker movement took center stage at this year’s South by Southwest Interactive Festival in Austin, Texas. The coveted opening keynote was delivered by Bre Pettis, CEO of 3-D-printer manufacturer MakerBot Industries, who used the occasion to unveil the Digitizer, a desktop device capable of scanning objects up to 8 inches in height using lasers and a webcam, streamlining the printing infrastructure from end to end. “You can fill the world with garden gnomes if you want,” Pettis joked.The onstage debut was an homage to Maker-Bot’s origins: In early 2009 Pettis was part of a collective of hackers who wanted to get their hands on a 3-D printer, which at the time were the size of mainframe computers and cost about $100,000. “We couldn’t afford one, so we made it,” he says. They got a rough prototype working before SXSW that year, so Pettis hopped on a plane, headed to Austin bars and began printing shot glasses with the device. He and his co-founders sold some 20 printers in just a few days.The latest model from Brooklyn-based MakerBot, the fourth-generation Replicator 2, costs $2,199 and is the size of a large toaster oven. It works by meticulously layering thin sheets of bioplastic material to create three-dimensional objects–a process made all the more mesmerizing under a lighting scheme reminiscent of a Virgin America cabin.Related: MakerBot’s Bre Pettis on the Next Industrial RevolutionMakerBot’s Bre Pettis.MakerBot’s range of industrial and personal printers has been a major catalyst in the hardware revolution, unlocking the ability for anyone to make things faster and more cheaply. Growth has been wild. In four years MakerBot has gone from three employees to more than 200; at press time the company had 50-plus job listings. There are some 20,000 printers in use (close to a quarter of total market share) and an estimated 115 million potential users globally (40 percent of orders are from outside the U.S.). NASA’s Jet Propulsion Laboratory is the biggest customer, but the printers are also a boon to smaller operations like Robohand, creator of open-source prosthetic hands for children, and even to one geek dad who printed custom foot molds to help his kid pass the minimum height requirement at an amusement park.”We’re not just a hardware company,” Pettis says, noting that MakerBot also creates firmware and has a partnership with Autodesk, which makes software with rendering capabilities. And this fall’s release of the Digitizer–which should cost roughly the same as the Replicator if Pettis’ “washer-dryer” analogy is any indication–will further build out the company’s position in the 3-D-printing ecosystem. And this is all just scratching the surface: “I think one day people will buy printers like they buy iPhones,” he says. “If you put your MakerBot goggles on … anything is possible. It’s a frontier, and we’re going to explore it.”
Firefox 70 shows an indicator when geolocation has been used by Martin Brinkmann on August 09, 2019 in Firefox – 26 commentsAll modern web browsers support the HTML5 Geolocation API that allows sites, with the permission of the user, to get the geographical position.The feature is used by numerous services on the Internet including mapping services that use it to quickly find out about a user’s location, services that provide regional versions of their sites, or services that provide suggestions that it bases on a user’s geographical region.Most browsers (all?) don’t indicate when a site uses the geolocation API. While it may be obvious at times, e.g. when you allow location access and a maps service focuses the map on that location, you may not know about it when it is not clear immediately.While you could and should assume that a site uses location information once you give it permission to use the API, you may want to know when and if it uses it.Firefox 70 includes an indicator that reveals when a site accessed the location for the last time. A click on the shield icon in the Firefox address bar displays the permissions that you gave the site in question. If you gave it permission to access location data, you will see the last access listed there underneath the permission.The bug listing on Mozilla’s bug tracking website dates back nine years. Mozilla wanted to better visualize the use of location by sites in Firefox to indicate the use of the API permanently for as long as the permission was granted.Firefox 70 displays an icon in its address bar to indicate use of the location API; previous versions of the web browser display no icon which means that users don’t see directly whether they have given a site (temporary) location access.It is a small change but it improves visibility of the permission significantly in the web browser.Firefox 70 is scheduled for a release on October 23, 2019 if the schedule is not changed. The next stable version of the Firefox web browser is Firefox 69 which is scheduled to be released on September 3, 2019.Firefox users can disable the geolocation feature entirely in the web browser.SummaryArticle NameFirefox 70 shows an indicator when geolocation has been usedDescriptionMozilla plans to add a location indicator to Firefox 70 that highlights permanently if a site has been given access to the location feature.Author Martin BrinkmannPublisher Ghacks Technology NewsLogo Advertisement
Posted by “Transat’s future is very bright”: Transat marks 30 years since its first Toronto-London flight Tags: Transat Tuesday, April 24, 2018 Share Transat had two Lockheed aircraft back in those days, and a vision that has endured, said Eustache: “We have always tried to offer traveller affordable products that encourage them to travel the world.”He added: “I am exceedingly proud when I look back at how far we’ve come since that first flight out of Toronto, and how much the company has grown in Ontario and the rest of Canada. Over the years, our organization has adjusted to a changing and ever more competitive business environment. It has evolved and rapidly responded to emerging consumer needs when it comes to products, destinations, services, and of course price.More news: Consolidation in the cruise industry as PONANT set to acquire Paul Gauguin Cruises“We work in a vibrant industry full of stimulating challenges, which is seeing steady growth. And there is no shortage of travellers. We are moving forward enthusiastically and optimistically.”Eustache said that Transat “is above all a leisure travel company” and is working actively to achieve its growth strategy. By combining Transat’s new hotels initiative with its existing leisure-travel business, “we will remain on the leading edge of travel industry innovation. We aim to stay at the forefront of the travel industry.”Earlier this year Transat tapped Jordi Solé to head up its Hotel Division. TORONTO — A gleaming white and blue A330-200, part of Transat’s strategic move to an all-Airbus fleet, was a fitting backdrop for last night’s 30th anniversary celebrations marking Transat’s first flight from Toronto to London, a buzzy event that drew hundreds of industry execs, colleagues and friends to the Air Transat hangar at Toronto Pearson Airport.Transat rewarded agents all throughout last year with Surprise Dates, prize giveaways and special incentives, to commemorate three decades since Transat took flight with sun routes, the first to Acapulco in 1987.Last night the celebratory mood continued – and so did the prizes – as Transat gave away three trips to the Transat destination of the winner’s choosing, to mark 30 years since Transat took wing across the Atlantic with service from Toronto to London.Jordi Solé, President, Hotel Division, Transat and Jean-Marc Eustache, President and CEO, TransatOver the years Transat grew to become Canada’s first integrated international tourism company and its lineup now includes 60 destinations in two major markets – transatlantic (Europe and the Middle East) and the South – out of 21 airports across Canada. It also commercializes flights to Canada in 13 European countries as well as in Israel, the U.S. and its sun destination countries.More news: Transat calls Groupe Mach’s latest offer “highly abusive, coercive and misleading”Addressing the crowd at last night’s event, Transat President and CEO Jean-Marc Eustache sent out a special thank you to industry veteran Errol Francis, who took a chance on Transat back in those early days. After retiring from the travel industry Francis, in attendance last night, got into the real estate game, noted Eustache. “He tells me he’s happy, he’s not working too hard and he’s making lots of money,” Eustache joked. Francis’ support was pivotal in getting Transat off the ground, said Eustache, adding: “I want to thank him.” Eustache also lauded Transat’s Chief Operating Officer, Annick Guérard, an integral part of Transat’s succession plan as Eustache eyes retirement: “Annick will be terrific, ten times better than me.”Mississauga Mayor Bonnie Crombie, among the dignitaries at last night’s event, said Transat is renowned for its excellent customer service and top-notch fleet. “Transat’s future is very bright.”Among the company’s distinctions and awards (2017–2018), Transat was named the world’s second-best leisure airline and best in North America at the Skytrax World Airline Awards.After three decades Transat remains steadfast in its mission, said Eustache: “to brighten the days of travellers with the joys of vacations.” Travelweek Group << Previous PostNext Post >>
