| 智利上空出現大量奇特雲彩 形狀酷似UFO 
 近日,一名俄羅斯業余攝影師在智利的百內國家公園拍到了一幅奇景。天空中出現了幾朵碟形雲彩。它們在陽光的映照下呈橘黃色,像極了科幻電影中的UFO。
 
 這種“UFO雲”的學名叫莢狀雲,是一種自然天氣現像,經常在濕潤空氣經過山脈上空時出現。如果空氣在經過山脈上空時溫度下降,空氣中的水分就會凝結成莢狀雲。
 
 為了拍攝這些莢狀雲,47歲攝影師德米特裡和他的朋友在冷風裡站了好幾個小時。不過他表示,能拍到這樣的奇景,他覺得這一切都是值得的。
 
 Don't panic! UFO-shaped clouds sweep across sky in Chile
 
 Stunning pictures capture rare saucer-shaped cloud formations that could be mistaken for an alien invasionClouds spotted above a mountain range in a national park in Chile
 At first glance these images could be mistaken for an imminent alien invasion, but the mysterious 'UFOs' seen floating over a mountain range are in fact clouds.
 
 The rare formations - known as lenticular clouds - have been mistaken for UFOs thanks to their smooth, flying saucer-like shape and orange glow.
 
 The clouds, which form in areas of high altitude, often baffle onlookers and have sparked fears of alien attacks.

 Despite their sinister appearance, the cloud formations are a natural weather phenomenon created when moist air flows over a mountain or mountain range.
 
 If the temperature in the air drops, the moisture condenses forming a spiral-shaped lenticular cloud.
 
 These stunning pictures were captured in Chile by Russian amateur photographer Dmitry Dubikovskiy while he was travelling with friends.
 
 The 47-year-old was 'euphoric' when he spotted the rare cloud formations in the skies over Torres Del Paine National Park.
 
 'It was a really stunning view,' he said.
 
 'Lenticular clouds always look unusual and against teh light of a sunset they look even more magnificent.
 
 'Whenever I go out for dinner with my friends, they all want to see the pictures and talk about how unique they are.
 
 'I've only seen this sort of phenomenon a few times in my life but each time I see it I think it's amazing,' the photographer added.
 
 'The feeling when I saw the clouds in Chile was similar to euphoria.
 
 'Despite having to be out in the freezing and gusty wind conditions for a few hours to capture these pictures, it was completely worth it when I saw the finished work,' Mr Dubikovskiy said.
