Of course , defined by the path of the sun through planet earth 's sky , the ecliptic plane rides low during july nights in the northern hemisphere 's summer skies .
当然,可由此从行星地球的天空中辨认太阳的运行轨迹,黄道平面在北半球夏季七月的天空中的位置很低。
Ghostly zodiacal light , featured near the center of this remarkable panorama , is produced as sunlight is scattered by dust in the solar system 's ecliptic plane .
朦胧的黄道光,在这张全景照片的中间,是太阳系黄道平面上的尘埃散射太阳光而形成。
The method of contiguity was that adopted by the ancient egyptians and the greeks ; it involved the observation of heliacal risings and settings , i.e.the risings and settings of stars near the ecliptic just before sunrise and just after sunset .
The plane of the ecliptic is illustrated in this clementine star tracker camera image which reveals ( from right to left ) the moon lit by earthshine , the sun 's corona rising over the moon 's dark limb and the planets saturn , mars and mercury .
Attention was concentrated on the horizon and the ecliptic .
关注重点在于地平线和黄道。
The ecliptic plane is defined as the imaginary plane containing the earth 's orbit around the sun .
黄道平面是一个假想的平面,理论上它包含了地球环绕太阳运行的轨道。
Saturn still shines in the night though , farther eastward along the ecliptic plane .
而沿着黄道平面朝更远的东方,土星仍在夜空中闪亮。
Many european scholars have found it almost impossible to believe that a fully equatorial system of astronomy could have grown up without passing through an ecliptic ( zodiacal ) phase , yet that undoubtedly happened .
