据美国每日科学网报道, 欧洲南方天文台的工作人员通过极大望远镜拍摄到一幅非常漂亮的太阳照片,照片中的太阳发出蓝绿色的闪光,这和所谓的“对日照”(Gegenschein)都是十分难得一见的景象。地球大气是可以散射阳光的巨大棱镜,而要想观察到这瞬间即逝的绿色闪光必须是在极为理想的大气条件下,要能清晰地看到日落的太阳和拥有十分稳定的大气。而位于智利北部阿塔卡尔沙漠的帕拉那山完全具备观测此绿色闪光的上述条...

北京时间2008年10月9日消息,据美国宇航局网站报道,在美国宇航局拉马第高能太阳光谱成像探测器(以下简称RHESSI)帮助下,科学家对太阳的圆度进行了精确度空前的测量。测量结果显示太阳并不是一个完美球体。在活动较为剧烈的年份,太阳会形成一层薄薄的“香瓜皮”,在很大程度上增加了其外观的扁率,此时的赤道半径略大于极半径。
