From the planetary scale to the cosmic scale, astronomers are throwing away textbooks.Wrong About Planets‘Totally Wrong’ on Jupiter: What Scientists Gleaned from NASA’s Juno Mission (Space.com). The Juno mission has brought earthlings their first images of Jupiter’s poles, and new estimates of processes deep inside the giant planet. Here’s what this article says:Before NASA sent its Juno spacecraft to explore Jupiter, astronomers were “totally wrong” about much of what they thought they knew about the planet, the mission’s principal investigator, Scott Bolton, said during a lecture here at the 231st meeting of the American Astronomical Society on Tuesday (Jan. 9)….“Our ideas were totally wrong about the interior structure, about the atmosphere, [and] even about the magnetosphere,” Bolton said. Astronomers believed that Jupiter had either a very small and dense core, or perhaps no core at all. But data from Juno revealed that Jupiter has an enormous, “fuzzy” core that might be partially dissolved. This discrepancy between scientists’ expectations and the data suggests that there’s a lot we still don’t know about giant gas planets, he explained….Jupiter South Pole from Juno (NASA/JPL)Juno is the first space mission to get a good look at the poles, and the mission’s scientists did not expect them to look as weird and chaotic as they do, Bolton said. “Had someone shown me a picture of just the pole 10 years ago, I never would have guessed it was Jupiter.”While scientists and astronomers have been scratching their heads over all these new groundbreaking discoveries enabled by the Juno spacecraft, the photographs Juno has taken of Jupiter have been similarly mind-boggling, Bolton said. Juno’s raw images, taken by the spacecraft’s JunoCam, are available online for citizen-scientists to download and process, and people have helped to create the most amazing images of Jupiter the world has ever seen. “I’m not sure that anybody on my team was ready for Jupiter to look like that,” Bolton said. “We were just startled.”Wrong About ExoplanetsPlanets around other stars are like peas in a pod (Science Daily). The Kepler Mission had already forced revision of astronomical predictions that planetary systems around other stars would resemble our solar system. Now, a new survey of 909 planets in 355 stellar systems, led by Lauren Weiss at the University of Montreal, shows that exoplanets tend to be regularly spaced. The findings require new ideas, invoking unobserved past interactions, to explain why our solar system is so different.“The planets in a system tend to be the same size and regularly spaced, like peas in a pod. These patterns would not occur if the planet sizes or spacings were drawn at random.” explains Weiss….Regardless of their outer populations, the similarity of planets in the inner regions of extrasolar systems requires an explanation.Wrong About StarsNature article turns theory of stellar evolution upside-down (Phys.org). Study of a white dwarf not only challenges theories about these specific objects, thought to be the end points of stellar evolution, but of stellar evolution theory itself. White dwarfs are thought to be the end products of 97% of stars in the universe. This upset was published by “Nature, one of the world’s top science magazines,” the article notes.This week, Nature published an article that could challenge the theory of stellar evolution.“I think that, over the coming months, stellar astrophysicists will have to redo their calculations,” said Gilles Fontaine, a physics professor at Université de Montréal and one of the authors of the article, titled “A large oxygen-dominated core from the seismic cartography of a pulsating white dwarf.”…When examining the star, located at the edges of the Cygnus and Lyra constellations, the researchers discovered that its carbon and oxygen core was twice as big as the theory predicted. “This is a major discovery that will force us to re-evaluate our view of how stars die,” said Fontaine. “That said, more work must be done to confirm whether this observation holds true for other stars. It may just be an anomaly.”Wrong About the Universe‘Serious gap’ in cosmic expansion rate hints at new physics (BBC News). One of the winners of the Nobel Prize for Physics in 2011, Adam Riess, is having doubts about the measurements that led to his award. He may have to invent a new particle to close the gap.A mathematical discrepancy in the expansion rate of the Universe is now “pretty serious”, and could point the way to a major discovery in physics, says a Nobel laureate.The most recent results suggest the inconsistency is not going away….What this all suggested, he said, was that the Universe is now expanding 9% faster than expected based on the data – a result he described as “remarkable”.One way to bridge the divide is to invoke new phenomena in physics.The new particle might be a “sterile neutrino,” the article guesses. “Another possibility is that dark energy behaves in a different way now compared with how it did in the early history of the cosmos.” Would that ad hoc suggestion not lead to another conundrum about fine-tuning, leading to wonder about how humans live in a privileged time when the earth is habitable and we can see a universe filled with stars?Historical science is fun. You can be totally wrong, change your story, invoke unseen phenomena, and claim you are providing “understanding” of reality. And the media and public will believe you and let you keep your job.(Visited 1,656 times, 1 visits today)FacebookTwitterPinterestSave分享0

zoomSource: Pixabay The number of major incidents in the Port of Singapore has dropped over the last 10 years, according to MPA Singapore.There were fewer than 0.12 major incidents per 100,000 vessel movements in 2018, down from 0.8 in 2009.“The use of technology and digitalisation can further enhance maritime safety by providing seafarers better access to critical safety-related information and early warning of potential incidents,” Lam Pin Min, Senior Minister of State for Transport and Health, said at the fourth International [email protected] Conference.Besides [email protected], MPA Singapore will also be pushing for digitalisation in two other areas.Namely, the authority said it would embark on the “Digital OCEANS” strategy to encourage Open or Common Exchange And Network Standardisation. This strategy aims to allow digital platforms of port authorities e.g. maritime single windows of shipping lines and of logistics service providers to link up.This will allow business entities, government agencies, and vessels to connect seamlessly between different digital platforms and achieve end-to-end connectivity.Additionally, MPA is supporting the International Association of Marine Aids to Navigation and Lighthouse Authorities (IALA) in operationalising the International Maritime Organization’s (IMO) concept of e-navigation for vessels which aims to make marine navigation safer and digitalise key maritime services.MPA said that these initiatives will improve efficiency, reduce transaction costs and enhance maritime safety.MOUs with Centre of Excellence in Maritime SafetyDuring the [email protected] Conference, three memoranda of understanding (MOUs) were signed following the launch of the Centre of Excellence in Maritime Safety (CEMS) last year.The MOUs were signed with A*STAR’s Institute of High Performance Computing to conduct research in human behavioural analytics, advanced computational models and intelligent maritime traffic simulation in navigational safety; with Singapore’s Transport Safety Investigation Bureau to jointly promote and enhance maritime safety investigations via the development of immersive training platforms and programmes; and with Group Nautical Pte Limited to create, design and develop Virtual Reality maritime training courses using immersive technologies.
Ohio State senior guard Kelsey Mitchell shoots a shot during the Buckeyes’ game against Washington on Nov. 19. Credit: Colin Hass-Hill | Sports EditorAfter an 84-75 loss to No. 19 Michigan Tuesday night, the No. 8 Ohio State women’s basketball team (16-3, 5-1 Big Ten) will head on the road for a Monday night game against No. 14 Maryland (16-3, 5-1 Big Ten). In the last matchup between the two teams, the Buckeyes upset the No. 2 Terrapins 98-87 at the end of the regular season last year. In recent years, Maryland has been the Big Ten’s powerhouse, winning the conference the past two years. Though this year’s Terrapin team lacks the star-power of recent years, Ohio State head coach Kevin McGuff stressed his team’s need to be prepared for another top-25 team.“They’re good, they’re talented, they’re well coached, they’re used to winning,” Ohio State head coach Kevin McGuff said. “They have an expectation to win. They’re gonna be ready. We’ll have to be really good on Monday.”The Terrapins have won 14 of their last 15 games with the lone loss coming Jan. 11 against the Michigan State Spartans.Redshirt senior guard Linnae Harper said the team will need to come in with the same level of intensity if it hopes to come away with a win against the Terrapins, like it did last year.“The amount of focus that we had, the amount of intensity and effort we brought, all of us that played that game we just brought it,” Harper said. “We played together, our chemistry was great and we really wanted to win. We have to approach this upcoming game the same way we approached it last year and make sure that we’re doing everything we have to do to get the win.”Maryland sophomore guard Kaila Charles, who leads her team in scoring with 17.1 points per game, must pick up the workload offensively. The Terrapins’ second-leading scorer, sophomore guard Blair Watson, suffered a torn ACL in a January practice that will force her to miss the remainder of the season. Watson was averaging 13.8 points per game prior to the injury.The Terrapins’ depth has helped them absorb the loss of Watson this season. Maryland has six active players who put up at least 10.5 points per game, and would have been seven had Watson not suffered a season-ending injury.This game will have major implications on which team takes the edge in the Big Ten. Ohio State and Maryland are tied for first atop the conference and both are the only teams with one loss. Conference control is not McGuff’s main focus, though.“I just think it’s about us being prepared for this game and putting our best foot forward here, as we saw Tuesday anything can happen,” McGuff said. In the Big Ten there’s a lot of parity this year. We need to take this game first and go from there.”The Buckeyes will need to find a way to put up points on a night when the 3-pointer does not fall. While they were aggressive and hit 17-of-22 free throws the previous game, they shot 36 percent from the field, which hindered their second-half productivity. McGuff said he would like to see his team stay patient, even when shots aren’t dropping for the team. “One, continue to take good shots no matter what,” McGuff said. “Two, just continue to work [on it]. I think we’ve, knock on wood, done a better job recently getting some balance in our offense, scoring a little bit more around the basket and I think we need to continue to do that.”
Liverpool’s defender Virgil van Dijk is proud of his team’s work ethic in their hard-fought 1-0 win over Brighton at Anfield.Mohamed Salah finished curling finish in the 23rd minute put the Reds ahead but wasn’t the ideal scoreline against a team basking in the euphoria of their 3-2 win over Manchester United last week.As in the 2-0 win at Crystal Palace on Monday, Jurgen Klopp’s men showed a resilient side that pleased centre-back and record signing Van Dijk.“It was a tough game, we knew before the game Brighton were full of confidence, we just had to be ready for the battle,” he told BT Sport.“We didn’t play our best game but it’s very important that we won and kept it tight in the end.“We [defend] altogether. It starts up front, you can see how important it is.Virgil van Dijk praises Roberto Firmino after Liverpool’s win Andrew Smyth – September 14, 2019 Virgil van Dijk hailed team-mate Roberto Firmino after coming off the bench to inspire Liverpool to a 3-1 comeback win against Newcastle United.“Credit to everyone, we’re not doing it alone at the back, everyone’s doing their bit.“It’s always important, those crucial saves, so we’re happy to keep a clean sheet and win.”Salah now has 29 goals in as many appearances at Anfield, leaving Milner to marvel at his prolific team-mate.“Not a bad record is it. If Mo gets those chances he’ll take them,” he told BT Sport, before sending further praise in the direction of Van Dijk and the defence operating in front of Alisson – the Brazil goalkeeper already proving his worth after a big-money arrival from Roma.“The front three are always going to cause problems for most teams, that’s always going to get the headlines,” he added.“But the boys at the back, the goalkeeper and as a team keeping these clean sheets is so important. That’s what’s getting us the points.”
Gianluigi Buffon prays that he will never face old club Juventus in the Champions League final for Paris Saint-GermainThe veteran goalkeeper left the Serie A champions in the summer after 17 domestic trophy-laden years in favour of a free transfer to PSG.One of the prime reasons for Buffon’s shock switch to France at the age of 40 was to finally win the Champions League after losing three finals with Juventus.Now Buffon just hopes that he will not have to inflict another European final defeat on his old club with PSG among the favourites for the Champions League.“After a week, PSG realised they hadn’t signed someone who was getting old but rather someone wanted to carve out their place in the team and help them grow.,” Buffon told Gazzetta dello Sport.PSG ultras sent a warning letter to Neymar Manuel R. Medina – September 14, 2019 Brazilian superstar Neymar might play today his first game of the season for Paris Saint-Germain and the team’s ultras have warned him.“I got the role I wanted: one of making myself available to help the club grow and show I’m still good enough.“I have no regrets or disappointment about leaving Juve. My farewell was planned long ago and the chapter closed perfectly.“I was in Italy last week, I called Andrea [Agnelli] and he gave me permission to train at Continassa for three days.“If I had to face Juve in the Champions League, I’d prefer to do so before the Final because, if I was to win it, I wouldn’t my joy to coincide with the tears of my former teammates.”Although it remains uncertain whether PSG coach Thomas Tuchel would select Buffon for a Champions League final due to his intense rivalry with Alphonse Areola to be PSG’s number one.
South Dakota’s congressional delegation, as well as military officials, say the Air National Guard Base in Sioux Falls should be selected to host the F-35 Joint Strike Fighter.Joe Foss Field has access to uncongested airspace and can provide the necessary infrastructure, including two runways, needed to accommodate the fifth-generation fighter, Col. Russ Walz, commander of the 114th Fighter Wing, told the Argus Leader.“We feel real good about it,” Walz said Wednesday. The 114th is one of 18 fighter units that could host the F-35. The Air Force is expected to announce its basing decisions for the F-35 Joint Strike Fighter next year, including two Air National Guard locations.On Tuesday, the state’s congressional delegation, along with Gov. Dennis Daugaard (R) and Adjutant General Maj. Gen. Timothy Reisch, wrote to Air Force Secretary Deborah Lee James to urge her to consider basing the service’s newest fighter in Sioux Falls.“The 114th Fighter Wing has demonstrated outstanding mission readiness and a superior record of excellence, making South Dakota an ideal location as the next beddown site of the F-35 Joint Strike Fighter,” the delegation wrote.If selected, the F-35 likely wouldn’t arrive at Joe Foss Field until 2022, Walz said.
