A | 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。1月9日消息今日早些时候，有报道称，今天的头条已达到优酷的收购，正在与西瓜视频业务对接。据新浪科技新闻网报道，针对传言，优酷回应称：爆炸完全是胡说八道，严重影响优酷品牌声誉，优酷将追究相关自媒体传播虚假新闻的法律责任；字节弹跳副总裁李亮回应称“该消息不真实”；阿里·达文说，这个内容是虚假新闻，谣言应该承担法律责任。自从去年以来，关于购买优酷的传言就流传了。2018年12月21日，据《时代》和《金融新闻》报道，字节弹跳（今天的头条新闻和特雷莫洛母公司）正与阿里巴巴洽谈收购优酷和阿里巴巴音乐相关业务。据报道，这笔交易的金额高达50亿美元。优酷官方微博帖子叫“胡说”！今天的头条新闻也回应说“这个谣言不是真的”。优酷和阿里音乐阿里娱乐是阿里集团在娱乐领域培育的主要业务。成立于2016年10月31日。其中，阿里巴巴音乐于2015年3月16日正式成立，由阿里巴巴集团旗下的两个音乐服务机构，虾米音乐和阿里巴巴星球（每天都很美）合并而成。优酷于2016年4月6日完成私有化，正式成为阿里巴巴的全资子公司。
