在这张合成的天文照片中，当火星在地球的夜晚漫步时，它经过昴宿星团以南5度的地方。这张天景图是由从7月12日开始连续16个晴朗夜晚拍摄的一系列图像组成的。火星在视野中的行进从最右边开始，这颗行星的红润色调与蓝色的昴宿星团形成了鲜明的对比。相对于遥远的恒星，距离太阳的第四颗行星在天空中移动得更快，很容易就经过了第七颗行星天王星。7月16日，红色星球火星和这个巨大的冰行星紧密相接，相距约1/2度。继续它快速的向东跋涉，火星现在已经离开了姐妹恒星和外行星，经过红巨星毕宿五的北方。8月14日，火星将在地球天空中接近木星的1/3度。

As Mars wanders through Earth's night, it passes about 5 degrees south of the Pleiades star cluster in this composite astrophoto. The skyview was constructed from a series of images captured over a run of 16 consecutive clear nights beginning on July 12. Mars' march across the field of view begins at the far right, the planet's ruddy hue showing a nice contrast with the blue Pleiades stars. Moving much faster across the sky against the distant stars, the fourth planet from the Sun easily passes seventh planet Uranus. Red planet Mars and the ice giant world were in close conjunction, about 1/2 degree apart, on July 16. Continuing its rapid eastward trek, Mars has now left the sister stars and outer planet behind though, passing north of red giant star Aldebaran. Mars will come within about 1/3 degree of Jupiter in planet Earth's sky on August 14.
