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。    每日商报讯 杭城的跑友们请注意，2026江苏银行杭州湘湖半程马拉松将于10月18日鸣枪起跑，眼下，报名通道已正式开启，感兴趣的市民朋友记得看好时间。在赛事设置上，今年的湘湖半马分为男子、女子两个组别（21.0975公里），赛事规模限制为10000人，参赛选手须年满18周岁（2008年1月1日前出生）。10月18日7点30分，跑者将于湘浦路的起点处出发，途径湘湖路、眉山路、湘云路、金秀路、南六路，并在南六路与风情大道交会口折返后沿南六路、定山路、湘虎路、湘湖七彩绿道、湘师路、湘湖院士岛、湘虎路、越王路最终抵达终点下孙文化村。跑者可以通过赛事官网“www.xianghumarathon.com”或微信公众号“杭州湘湖马拉松”参与报名，报名通道将于8月28日18点截止。需要提醒的是，若报名人数超出限制人数，需等待抽签结果，届时将于2026年9月中旬公布抽签结果，中签之后才算真正的报名成功，可获得今年的参赛资格。和以往不同的是，本届赛事不再设置欢乐跑项目，仅保留半程马拉松。如果想带小朋友一起参与跑步活动，11月8日在湘湖将有一场专门为亲子家庭打造的赛事，大家可以通过“湘湖发布”了解详情。
