For the first time, astronomers have seen a dusty disk of material around a young star fragmenting into a multiple-star system. Scientists had suspected such a process, caused by gravitational instabi...
欧洲航天局火星探测器分离成功
欧洲航天局 火星 探测器 成功
2016/10/19
欧洲航天局火星登陆器“斯基亚帕雷利”10月16日脱离母船，朝火星表面下降，预计19日着陆，开始为期3天的考察，探寻生命迹象。格林尼治时间16日14时42分（北京时间22时42分），“斯基亚帕雷利”按计划同母船“微量气体探测器”分离。尽管地面控制中心起初没能从母船收到关于“斯基亚帕雷利”状态的信号，但欧航局说已经恢复同探测器的联络。
银河系外首次发现星系热核
银河系外 星系 热核
2016/9/7
由日本东北大学、东京大学、国立天文台和筑波大学组成的研究小组近日首次发现，银河系外的星系中刚刚诞生的星球被热核包围。通过对热核数据的详细分析，发现包围天体的气体化学成分与银河系同种天体相比有很大不同。这一结果显示，新生星球周围物质的化学性质受星系个性的强烈影响，这是对形成星球和行星的物质化学性质研究迈出的重要一步。
Dwarf galaxies are enigmas wrapped in riddles. Although they are the smallest galaxies, they represent some of the biggest mysteries about our universe. While many dwarf galaxies surround our own Milk...
