Report: UK Defense Secretary is Using Ukraine Conflict to Demand Bigger Budget_我的网站

A |     British Defence Secretary Ben Wallace wants a major hike in armed forces spending in response to the conflict in Ukraine.,The BBC reported that Wallace will call on Chancellor of the exchequer Rishi Sunak to raise defense spending from around two per cent of GDP — the NATO target figure — to 2.5 percent.,The minister is expected to make comments to that effect when he addresses the Royal United Services Institute (RUSI) Land Warfare Conference in Westminster later on Tuesday, before flying to Madrid for the NATO summit there.,"The defense secretary is expected to emphasize that now that the threat has changed, governments must be prepared to invest to keep us safe," said a defense source quoted by Sky News.,"We do not comment on alleged leaks," another defense source insisted, adding: "The defense secretary and the prime minister have always said that the government will respond to any changes in threat, which is why in 2020 the Ministry of Defence received a record defense settlement.",Britain has sent a battalion-sized force of soldiers to Estonia in a bid to confront Russia, while supplying Ukraine with thousands of man-portable anti-tank and anti-aircraft weapons, over 120 armored vehicles and three M270 multiple-launch rocket artillery systems.,Wallace claimed earlier in June that Western military aid was helping the Ukrainian military make "significant progress" in the east of the country against Russian and Donbass forces. But recent days saw the capture of the city of Severodonetsk and a string of smaller settlements in Lugansk, with up to 8,000 Ukrainian troops now trapped in Lisichansk.,British Chief of General Staff General Sir Patrick Sanders told the Royal United Services Institute (RUSI) conference on Tuesday morning that the crisis in Ukraine was "our 1937 moment" — a possible reference to then-prime minister Neville Chamberlain's simultaneous policy of appeasing towards Nazi Germany while re-arming Britain.,Sanders said his focus was on "mobilizing the army to meet the new threat we face", insisting: "The British Army is not mobilizing to provoke war, it is mobilizing to prevent war.",NATO Could Expand Eastern European Battlegroups to Brigade or Division-Size Forces: Report26 June, 15:49 GMT,The general called the scale of the conflict in Ukraine "unprecedented.","In all my years in uniform I haven't known such a clear threat to the principals of sovereignty and democracy and the freedom to live without fear of violence as the brutal aggression of President Putin and his expansionist ambitions," Sanders said.,"This is our 1937 moment," he added. "We are not at war but must act rapidly so that we aren't drawn into one through a failure to contain territorial expansion… I will do everything in my power to ensure that the British Army plays its part in averting war."。    这张图像展示了已知最大星系IC1101。图片来源：NASA/ESA/哈勃太空望远镜　　据ScienceNews网站最新报道，包括西班牙天文学家在内的联合团队通过超深成像观测确认已知最大星系边界。

B | 这个名为IC1101的星系直径达到约520千秒差距（星系尺度单位），接近170万光年，宽度相当于17个银河系并排排列，而这个星系目前还在成长。　　确定这一尺度的关键，是天文学家获取了迄今对IC1101曝光时间最长、探测最深的影像。这些图像由位于西班牙加那利群岛拉帕尔马岛的艾萨克·牛顿望远镜于早前拍摄。经过最新详细测算，天文学家得以识别这颗巨星系暗淡的外缘，同时算出IC1101的恒星物质总质量约为3.4万亿个太阳质量。　　IC1101坐落在距地球超过10亿光年的Abell2029星系团中心，是该星系团中光度最高的星系。这类星系位居宇宙中最庞大星系之列，其成长方式是通过反复吞并附近较小的星系来不断扩张，这一过程被称作星系同类相食。　　此前的研究已经暗示IC1101体量巨大，但始终未能精确界定星系本体与外围星系团弥散物质之间的过渡边界。本次超深观测填补了这一空白。

C | 加那利天体物理研究所的天文学家们在星系边缘识别出带状尾流结构，认为这是IC1101与其他星系发生并合的产物，表明该星系迄今仍在吸积物质，生长并未停止。　　加那利天体物理研究所天文学家卡洛斯·马雷罗-德拉罗萨表示，IC1101展示了涉及反复并合与吸积的星系演化过程在极端尺度上的样貌，是可参照的星系未来演变样本。

D | 　　这次边界判定之所以重要，是因为最亮团星系的暗弱外围通常会混入星系团的弥漫星光，导致很难判断巨星系本体的终结位置。

E | IC1101的测量结果为这类天体的尺度研究提供了方法论样本。作为已知最大的星系，它的存在也揭示了在数十亿年的时间尺度上，宇宙中的最大尺度星系结构可以通过持续吞并周围星系而发展到何等极端的规模。（记者张梦然）。
