Scientists Discover Matter Jet From Black Hole 50 Times Bigger Than Its Galaxy_我的网站
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。 兰州8月25日电 (刘薛梅)今年是国家数据局确定的“数据要素价值释放年”。
B | 甘肃省政府办公厅副主任、省数据局副局长刘灿林25日表示，依托国家数据基础设施(甘肃)区域功能节点，已建成甘肃省公共数据资源登记平台和授权运营平台，形成数据资源登记的“存证-管理-公示-赋码-发证”全链路闭环，为全省公共数据资源开发利用筑牢基础底座。 当日，甘肃省数据局和甘肃省委宣传部新闻处围绕甘肃省公共数据资源登记管理和授权运营工作召开新闻通气会。 2025年9月，经甘肃省政府批准同意，按照“一局一中心一集团”运行架构，由丝绸之路信息港公司承接“甘肃省数据集团”职能。一年来，甘肃省数据集团获批建设了国家数据基础设施(甘肃)区域功能节点，成为全国7家获批项目之一，被列入“十五五”期间109项国家重点项目，目前项目一期建成投运，甘肃节点和国家全域节点正式贯通，并与全国30个功能节点、236个业务节点实现互联互通。 甘肃省数据局公众号近期发布的甘肃省第一批公共数据“跑起来”典型案例——沙戈荒能源数据驱动电碳生态升级中提到，首创“电-碳-生态”算法模型，以电力数据为核心，融合多方数据，全面捕捉和反映沙漠能源生态圈的实际情况，揭示各层面数据相互关系，加速激活数据要素乘数效应。 该案例呈现出，实现了对武威沙漠区域内367家企业、10处沙漠文旅景区及41家新能源场站碳减排量和碳汇量的精准核算，为碳资产价值评估奠定数据基础。 甘肃省大数据中心副主任徐海滨说，目前，公共数据资源登记平台已与国家平台对接联通，实现数据实时上报、登记结果互通互认；公共数据授权运营平台已配齐数据沙箱、区块链存证、安全网闸等多重安全管控模块，对接省政务数据共享平台，实现数据流转通道复用，为公共数据产品合规开发提供支撑。 甘肃省数据集团探索创新“数据工场”甘肃模式，搭建数据集空间、数模空间、创意空间，面向各类开发主体提供数据治理、模型调用、应用开发、测试验证等服务，推动数据资源向数据产品和应用场景转化。现已接入企业和社会数据资源目录1280条，上架数据产品1218个，形成了数据汇集、治理、开发、创新应用等一体化运营模式。 为让数据更好赋能千行百业，甘肃着力培育建设了一批凸显甘肃特色且可复制推广的公共数据应用场景，有效牵引公共数据资源合规开发和创新应用，带动打通公共数据供给-流通-利用链条，促进数据要素全面融入经济价值创造过程。其中多个应用场景，成功入选国家公共数据“跑起来”示范场景。 刘灿林说，公共数据资源登记和授权运营是一项改革性工作，不能一蹴而就，要紧盯将甘肃打造成为黄河流域及西部地区数据要素创新应用和产业发展高地的目标，加快公共数据产品开发，让数据“供得出”，强化平台建设运营，让数据“流得动”，丰富数据应用场景，让数据“用得好”。
