Call me rocky: The intriguing image captured by Nasa on Mars

Life on Mars? Amazing photos from Nasa probe reveal mystery figure on Red Planet

Perched on a rock, she could be waiting for a bus.

But if so, she could be in for an awfully long wait.

This photo of what looks remarkably like a female figure with her arm outstretched, was taken on Mars.

Perhaps unsurprisingly, it has set the Internet abuzz with claims that there really is life on the red planet.

Others may well feel that it is simply an optical illusion caused by a landscape.

Painstaking: Space enthusiasts spent four years analysing this image, which on much closer inspection shows the 'alien'

The image was among many sent back to Earth by Spirit, Nasa's Mars explorer vehicle which landed there four years ago.

Initial inspections revealed nothing unusual, but closer examination by amateur astronomers has thrown up this intriguing picture.

As one enthusiast put it on a website: "These pictures are amazing. I couldn't believe my eyes when I saw what appears to be a naked alien running around on Mars."

Another, dismissing cynicism about the somewhat stony look of the "alien", wrote: "If you show me another rock in another photo from Mars, or Earth, that naturally looks like that, I will reconsider."

A third contributor, who might have come closer to the majority view, said: "Ah, the human eye can be tricked so easily."

　　据英国《每日邮报》1月23日报道，日前，美国宇航局“勇气”号火星探测器拍摄的一组图片显示，在火星荒凉的原野上竟然存在一个生命体。

　　依据图片显示，这是一位女性，裸体坐在岩石边，可清晰地看到她长着像人类一样的手臂，很可能在岩石上进行休息。当这组图片发表在互联网时，人们对此议论纷纷，有人称这是火星上真实的生命迹象，但也有人声称这可能是一种由地形导致的视觉幻想。

　　这组图片是由美国宇航局“勇气”号火星探测器向地面最新传送的，目前，“精神”号已在火星上服役4年之久。起初，研究人员对这组图片进行审核时并未发现有什么特殊之处，但是一位业余天文学家进行放大审核时发现了其中令人兴奋不已的画面。一位天文学家爱好者在互联网上留言称，“这些图片非常令人惊异!当我看到一位裸体外星人在火星上活动时真不敢相信自己的眼睛!”（From dailymail)
