Scientists Discover Matter Jet From Black Hole 50 Times Bigger Than Its Galaxy_我的网站

A |     作为NBA历史三双王，威少本有机会延续自己的三双纪录，但在宣布退役后，他的三双次数就定格在了209次，这项纪录可以说是相当有含金量。    One of the largest black hole jets in the sky has been uncovered by astronomers at Western Sydney University, new research published in the journal Monthly Notices of the Royal Astronomical Society has revealed.,According to the paper, in terms of distance from Earth, the galaxy NGC2663 is close by at just 93 million light-years.,With nearly ten times as many stars as our own Milky Way, it has the recognizable oval shape of a "typical" elliptical galaxy when viewed through a standard telescope. Led by astronomer Velibor Velovic of Western Sydney University, the research team used CSIRO's Australian Square Kilometre Array Pathfinder (ASKAP), a system of 36 connected radio dishes acting as a single super-telescope in Western Australia, to make their findings.,A core black hole's jet of material is visible in the radio waves as it leaves the galaxy. If our eyes could see it in the night sky, it would be larger than Earth's moon. This powerful torrent of material is approximately 50 times larger than the galaxy, stretched over almost 1 million light-years, according to the research.,The process studied by the scientists is rather similar to an effect seen in jet engines. The surrounding pressure pushes the exhaust plume from the sides as it rockets through the vacuum. As a result, the jet pulsates while expanding and contracting. Regular bright spots in the jet, called "shock diamonds" due to their shape, were observed by the team.,The flow glows brighter as it constricts.,Shock diamonds have been observed in smaller, galaxy-sized jets as well as in jet engines. Jets have been observed slamming into dense gas clouds, illuminating them as they pass through. However, a more subtle effect that makes it more difficult to see is the restriction of jets from the sides.,The paper underscored that astronomers have not observed this effect on such massive scales before NGC2663. This reportedly demonstrates that NGC2663 is surrounded by enough matter to push against the sides of the jet. The substance is then heated and pressurized by the jet.,A feedback loop is created when intergalactic matter enters a galaxy, which then creates a black hole that releases a jet. In turn, the jet decreases the inflow of intergalactic matter into galaxies. As the universe expands, these jets have an impact on how gas condenses into galaxies.,The Evolutionary Map of the Universe survey, which is also credited with discovering a new category of enigmatic astronomical object known as a "Odd Radio Circle," is still scanning the space.,‘Best Physical Models Can’t Fit The Data’: Radio Bursts Detected in Space ‘Defy’ Existing Theories7 August, 14:45 GMT。

B | 毕竟有很多球星职业生涯只拿到过一两次三双，甚至一些大家比较熟悉的超巨，职业生涯一次都没有做到过。

C | 哪怕是个人能力非常全面的詹姆斯，总共也只拿到了125次三双，距离威少的纪录还差84次。不过在现役NBA中，有一个球员，他其实非常有机会打破威少的三双纪录。         威少职业生涯4次场均三双          三双这项数据在16-17赛季之前并不是太常见，直到威少的出现，在16年夏天杜兰特宣布离开雷霆后，威少就独自扛起了球队。

D | 那个赛季威少几乎是打出了职业生涯最巅峰的表现，在球队其他球员很难站出来的情况下，威少大包大揽，场均拿到31.6分10.7篮板10.4助攻的豪华数据，在其他球员拿到一次三双就能开心很久的时候，威少就已经做到了场均三双，也是大O之后第一个做到这项成就的球员。

E | 所以那年威少凭借这种完美表现，力压哈登拿到了MVP奖杯。

F |          此后的威少拿三双就像家常便饭，加上20-21赛季在奇才拿到的一次场均三双，他总共四个赛季做到这项成就，排在NBA历史第一，也正是威少，将三双这项成就跟自己的名字牢牢绑在了一起，大家每次提到三双，下意识想到的球员就是威少。

G |          詹姆斯23个赛季拿了125次三双          威少在联盟中打了18个赛季，詹姆斯打了23个赛季，但詹姆斯的三双要比威少少得多。这其实主要是因为詹姆斯进入NBA的时间比较早，在职业生涯前中期联盟的比赛节奏还很慢，回合数比较少，所以篮板和助攻这两项数据很难同时上双。再往后到了小球时代，詹姆斯开始频繁拿到三双，但更多时候他总是差一两个篮板或助攻，尽管是这样，在比赛没有悬念的情况下，詹姆斯还是会坚决下场，不会为了无谓的数据让教练把自己留在场上。         下个赛季就是詹姆斯在NBA的第24年了，不过哪怕他还能再打两年，按照上个赛季总共拿到3次三双来计算的话，他也没办法超过威少的三双记录了。         现役仅约基奇有戏          约基奇在NBA历史三双榜中，其实仅次于威少，他总共拿到了198次三双，距离超越威少只差12次三双。要知道光上个赛季，约基奇就拿到了34次三双，并且可以砍下27.7分12.9篮板10.7助攻的场均三双数据，再往前去的24-25赛季，他也拿到了场均三双，连续两个赛季做到这项成就，仅次于威少。所以下个赛季约基奇只要正常发挥，超越威少的三双纪录不是什么问题。

H |          东契奇只有理论可能          其实东契奇也是一个拿三双的高手，作为一个持球大核，他职业生涯至今已经拿到了90次三双，排在NBA历史第七。只不过上个赛季的东契奇只拿到了8次三双，这个拿三双的频率并不是太高。         而且东契奇现在已经27岁了，就算他保持10个赛季的巅峰状态，按照一个赛季拿8次三双的数据来算的话，他的三双次数也会卡在170次左右，跟威少的209次还差得比较远。所以东契奇要想打破这项纪录的话，必须有一两个赛季大爆发，拿到30次三双左右，而这就比较考验他的比赛状态了。
