美国宇航局(NASA)“新视野号(New Horizons)探测器14日历史性地飞掠冰冷、阴暗的冥王星,在比以往更近的距离为人类观测太阳系最后一个未知世界。
请看外媒的报道:
Pluto shows a "heart" in a most detailed photo yet returned by NASA's approaching New Horizons probe, which has now begun its final run for its historic flyby of Pluto.
美国宇航局发射的“新视野号探测器即将传回的一张冥王星清晰照片上竟有一块心形的图案,“新视野号当时正在最后一次历史性飞掠冥王星。
In the early morning hours on Wednesday, mission scientists received the clearest image of the reddish-brownish dwarf planet by the Long Range Reconnaissance Imager (LORRI) aboard New Horizons, NASA said in a statement.
美国宇航局在一份声明中表示,15日凌晨时分,该行动的科学家收到了“新视野号上的远距离勘测成像仪拍摄到的最为清晰的一张冥王星的照片。
Flyby指航天器的近天体探测飞行(a flight made by a spacecraft over a particular place in order to record details about it),通常称为“飞掠。
冥王星是太阳系中最为神秘和鲜为人知的星球之一,其发现要追溯到85年前的1930年,年仅24岁的美国天文学家汤博(Clyde William Tombaugh)通过一点点查看星空照片,确认位于太阳系边缘的小光点为冥王星,并在英国11岁小女孩的建议下以希腊神话中冥王普鲁托(Pluto)的名字命名,认为它是太阳系的第九大行星。
国际天文学联合会2006年8月通过了新定义:“行星(planet)指的是围绕太阳运转、自身引力足以克服其刚体力而使天体呈圆球状、并且能够清除其轨道附近其他物体的天体。按照这个标准,由于冥王星位于柯伊伯带(Kuiper belt)中,在自己轨道附近还有其他天体,不能算作行星。对于这一类星体,天文学界定义了一个新类别“矮行星(dwarf planet)。
目前,太阳系的八大行星依序为水星(Mercury), 金星(Venus), 地球(Earth), 火星(Mars), 木星(Jupiter), 土星(Saturn), 天王星(Uranus), 海王星(Neptune).
