Video: A Perfect Solar Storm

Tag: 上海龙凤419LJ

first_imgOn 23 July 2012, two eruptions on the sun known as coronal mass ejections (CMEs) burst from an active patch of sunspots on the far side of the sun, which is monitored by a probe that circles the sun ahead of Earth in the same orbit. Emerging about 15 minutes apart, the CMEs quickly merged into one shock wave of charged particles that washed over the probe’s sensors just 18.6 hours later (the “snowstorm” of particles seen late in this video), researchers report online today in Nature Communications. Behind the shock wave, charged particles raced along at about 2250 kilometers per second—five times their normal speed at Earth’s distance from the sun—and the magnetic field strength there was more than 10 times that normally seen at Earth’s orbit. If pointed in our direction, such a combination would have produced the strongest geomagnetic storm to have struck Earth in history and could have knocked out satellites and earthbound power grids, researchers say. Fortunately, the event was a bit of a fluke, as it erupted into a region of space where the solar wind and the magnetic field had been weakened by a solar flare 4 days earlier. The observations of these CMEs will help scientists better model space weather and predict potentially calamitous solar storms.(Video credit: Ying Liu)Sign up for our daily newsletterGet more great content like this delivered right to you!Country *AfghanistanAland IslandsAlbaniaAlgeriaAndorraAngolaAnguillaAntarcticaAntigua and BarbudaArgentinaArmeniaArubaAustraliaAustriaAzerbaijanBahamasBahrainBangladeshBarbadosBelarusBelgiumBelizeBeninBermudaBhutanBolivia, Plurinational State ofBonaire, Sint Eustatius and SabaBosnia and HerzegovinaBotswanaBouvet IslandBrazilBritish Indian Ocean TerritoryBrunei DarussalamBulgariaBurkina FasoBurundiCambodiaCameroonCanadaCape VerdeCayman IslandsCentral African RepublicChadChileChinaChristmas IslandCocos (Keeling) IslandsColombiaComorosCongoCongo, The Democratic Republic of theCook IslandsCosta RicaCote D’IvoireCroatiaCubaCuraçaoCyprusCzech RepublicDenmarkDjiboutiDominicaDominican RepublicEcuadorEgyptEl SalvadorEquatorial GuineaEritreaEstoniaEthiopiaFalkland Islands (Malvinas)Faroe IslandsFijiFinlandFranceFrench GuianaFrench PolynesiaFrench Southern TerritoriesGabonGambiaGeorgiaGermanyGhanaGibraltarGreeceGreenlandGrenadaGuadeloupeGuatemalaGuernseyGuineaGuinea-BissauGuyanaHaitiHeard Island and Mcdonald IslandsHoly See (Vatican City State)HondurasHong KongHungaryIcelandIndiaIndonesiaIran, Islamic Republic ofIraqIrelandIsle of ManIsraelItalyJamaicaJapanJerseyJordanKazakhstanKenyaKiribatiKorea, Democratic People’s Republic ofKorea, Republic ofKuwaitKyrgyzstanLao People’s Democratic RepublicLatviaLebanonLesothoLiberiaLibyan Arab JamahiriyaLiechtensteinLithuaniaLuxembourgMacaoMacedonia, The Former Yugoslav Republic ofMadagascarMalawiMalaysiaMaldivesMaliMaltaMartiniqueMauritaniaMauritiusMayotteMexicoMoldova, Republic ofMonacoMongoliaMontenegroMontserratMoroccoMozambiqueMyanmarNamibiaNauruNepalNetherlandsNew CaledoniaNew ZealandNicaraguaNigerNigeriaNiueNorfolk IslandNorwayOmanPakistanPalestinianPanamaPapua New GuineaParaguayPeruPhilippinesPitcairnPolandPortugalQatarReunionRomaniaRussian FederationRWANDASaint Barthélemy Saint Helena, Ascension and Tristan da CunhaSaint Kitts and NevisSaint LuciaSaint Martin (French part)Saint Pierre and MiquelonSaint Vincent and the GrenadinesSamoaSan MarinoSao Tome and PrincipeSaudi ArabiaSenegalSerbiaSeychellesSierra LeoneSingaporeSint Maarten (Dutch part)SlovakiaSloveniaSolomon IslandsSomaliaSouth AfricaSouth Georgia and the South Sandwich IslandsSouth SudanSpainSri LankaSudanSurinameSvalbard and Jan MayenSwazilandSwedenSwitzerlandSyrian Arab RepublicTaiwanTajikistanTanzania, United Republic ofThailandTimor-LesteTogoTokelauTongaTrinidad and TobagoTunisiaTurkeyTurkmenistanTurks and Caicos IslandsTuvaluUgandaUkraineUnited Arab EmiratesUnited KingdomUnited StatesUruguayUzbekistanVanuatuVenezuela, Bolivarian Republic ofVietnamVirgin Islands, BritishWallis and FutunaWestern SaharaYemenZambiaZimbabweI also wish to receive emails from AAAS/Science and Science advertisers, including information on products, services and special offers which may include but are not limited to news, careers information & upcoming events.Required fields are included by an asterisk(*)last_img read more

first_imgAccording to the website, the measures are a direct result of that latest funding snag and were announced to employees last night in an email. The missive states that company CEO Jia Yueting will effectively eliminate his salary, reducing it to a single symbolic dollar. Hourly workers, meanwhile, will see their pay hacked back 20 percent. For executives, it may be even worse, with some supposedly accepting an even larger, though unspecified, cut.In exchange for a 45-percent share in the company, Evergrande Health had promised $2 billion, and indeed had already fronted $800 million of that amount. Unfortunately, the cash has already been used up and the Hong Kong exchange-listed outfit has balked over sending the next $500-million tranche.The aforementioned email explains the company is now “pursuing funding opportunities with those who share our vision,” after putting the blame for the current cash crisis at the feet of Evergrande Health, saying, “Faraday Future is facing issues with its current funding because of Evergrande’s failure to live up to its end of the bargain and make the payments it agreed to.”While we here at InsideEVs don’t see ourselves as highly-knowledgable business people, we have to believe it’s going to be very difficult to find a Future funding partner after the latest fiasco. Still, CEO Jia Yueting hasn’t thrown in the towel, so while there’s still life, there’s hope. We guess.Source: The Verge Faraday Future Establishes HQ In China Faraday Future Reports Problems With Evergrande Health’s Investment Author Liberty Access TechnologiesPosted on October 22, 2018Categories Electric Vehicle News The Future might not happenFaraday Future is again in a funk.

It announced in June it had found an additional $2 billion investment from the Evergrande Health Industry Group Limited (Evergrande Health), but earlier this month revealed a problem securing some of those funds.
