宇宙最大单一天体起源确认
宇宙 最大单 天体起源
2016/9/26
据美国《大众科学》在线版2016年9月22日消息称,欧洲研究人员发现一“滴”极其明亮的莱曼α斑点(LAB),并确认其形成于一个超巨椭圆星系。该莱曼α斑点横跨30万光年,是两个星系的家园,也是人类迄今已知的宇宙中最大天体之一。

首张 全天域宇宙辐射图 宇宙起源变迁
2010/7/14
据《每日邮报》报道,欧洲科学家利用“普朗克”天文望远镜完成首张全天域宇宙微波背景辐射图,这张辐射图成功捕捉到宇宙大爆炸遗留痕迹,将为研究宇宙起源演化的过程提供巨大帮助。据报道,这张历时6个月完成的宇宙辐射图全景展示了孕育人类的银河系的现状,同时提供了宇宙形成之初的珍贵信息。图像上遍布于整个银河的宇宙尘埃网络是正在形成或已经开始其生命历程的新星的摇篮。
美国确认宇宙射线由质子组成
美国 宇宙射线 质子
2010/7/7
美国研究人员在最新一期《物理评论快报》上报告称,他们使用位于犹他州的高分辨率蝇眼阵列望远镜,确认高能的宇宙射线由质子组成。美国的高分辨率蝇眼探测器(HiRes)位于犹他州盐湖城西的沙漠中,使用高分辨率的蝇眼探测器,科学家确认,在每个原子核中发现的带正电的成分(质子)组成了宇宙射线,而之前,科学家并不能确认这一点。
犹他州立大学的一名研究人员表示,该HiRes探测器采用立体观测技术,甚至能够探测这...
