• 最近,国家天文科学数据中心和新昌星空文化传媒合作,在万维望远镜(WWT)北京社区资源库里上线了一组360度×180度的新昌全景图,从鼓山公园、新昌体育场、翡翠山南复线、孝行路,还有孝行路十九峰路口等多个视角全方位地展现了如诗如画的新昌小城 ...
  • 近日,北京师范大学天文系苑海波副教授和研究生张若羿利用LAMOST和Gaia数据在仙女座星系(M31)和三角座星系(M33)的外围探测到了尘埃的信号。该成果发表在《天体物理学报通讯》上。
    在本星系群中,M31和M33分别是最大和第三大的星系,但探测这两个星系外围的尘埃依然非常具有挑战性。
    椭圆代表M31、M33以及两个伴星系M32和M101的光学范围。   图2:M31和M33尘埃红化图。
    M31和M33为中心的两个虚线椭圆表示其尘埃盘的大小,以M31为中心的大圆代表其尘埃晕的范围。
    在仔细地去除了SFD98尘埃图(它包含来自银河系、M31和M33的尘埃信号)的银河系前景信号后,研究人员揭示了M31和M33外围一个相当大区域内的尘埃分布情况。
