4月23日由美国航空航天管理局的“雨燕”号轨道卫星探测到,天文学家们拍下了所观察到的最为遥远的天体——130亿光年之外的一颗恒星,该恒星正在塌缩成为黑洞,由此产生伽马射线爆发。这次爆发显示,在宇宙大爆炸之后仅仅6亿年的时候,恒星就已经开始陆续地形成和灭亡了。天文学家们每周都能看到两三次伽马射线GRBs爆发现象,这种现象是恒 Detected by NASA’s Swift satellite on April 23, astronomers photographed one of the most distant objects observed - 130 billion light-years away - The stars are collapsing into black holes, resulting in gamma-ray bursts. The eruption shows that at a mere 600 million years after the Big Bang, stars have begun to form and perish. Astronomers can see two or three gamma-ray GRBs outbreaks every week, a phenomenon that is constant
