南方的十字架 Southern Cross

科學圖說 Scientific introduction

在南半球觀看銀河，不僅比北半球所見的明亮許多，色彩也更加豐富。夜空下的紐西蘭南島蒂卡波湖，是南半球的觀星聖地，也是世界上第一個暗夜星空保護區。當地特製的照明路燈，是為了避免光污染影響觀測星空。拍攝照片的同時，天空中人造衛星和流星運行的軌跡，恰好瞬間形成十字造型，與地面教堂屋頂的十字架遙相呼應。畫面右側清晰可見大小麥哲倫星雲。

From the Southern Hemisphere, the Milky Way appears brighter and richer in color than from the Northern Hemisphere. Lake Tekapo, on New Zealand’s South Island, is a sacred site for stargazers and the world’s first dark sky reserve. Specially produced streetlamps prevent light pollution from interfering with observations of the night skies. In this image, a manmade satellite in orbit and meteor form a cross-like shape, echoing the cross on the local church. On the right side, the Large Magellanic Cloud and Small Magellanic Cloud can be clearly seen.

水珠 Water Pearls

科學圖說 Scientific introduction

先鋪上黑色玻璃，在瘦果的棉絲上用針筒注射水滴，印證水的內聚力和張力極限。再用噴霧器噴灑，使水氣附著在棉絲上，水珠可持續變大。此時水的折射及反射背景顏色，既像水晶球又像外太空的美麗星球。只要不去碰它，可持續30分鐘不破掉！水的力量真是無法想像！

On top of black glass, water droplets were added to hair-like structures of achenes with a syringe, testing the limits of cohesion and tension. Then, a sprayer was used to attach mist droplets to the hair-like structures, with some of these “water pearls” growing in size. Refraction and reflection created the background colors. The water droplets appear like crystal balls or beautiful orbs. As long as they were not disturbed, they could stay in place for 30 minutes. The strength of water is amazing!

巧遇蛇蜥護卵 Glass Lizard Protecting Its Eggs

科學圖說 Scientific introduction

臺灣中海拔潮濕森林中，棲息著一種奇特的爬行動物──脆蛇蜥(又名哈特氏蛇蜥)。牠是臺灣最大型的蜥蜴，卻因特殊的生態習性而非常罕見。牠的外觀似蛇類，但其實是沒有腳的蜥蜴，很特別吧？那次的意外相遇，幸運記錄到即將脫皮而體色偏白的雌性個體；更幸運的是，記錄到罕見的護卵行為。當下因興奮顫抖到連相機都拿不穩，但又怕驚動到牠，逼迫自己儘可能保持冷靜，複雜的情緒難以言喻，很高興能將這美好的一幕記錄下來。

In the damp forests in mid-elevation areas in Taiwan lives a unique reptile – Dopasia harti. It looks like a snake, but is actually a legless lizard and the largest lizard species in Taiwan. Due to its particular ecological habits, it is rarely seen. I was fortunate to encounter this female in the process of shedding its skin, which is why it appears whitish in color. I was even more fortunate to record its rarely seen egg protecting behavior. I was so excited that I was shaking and had a difficult time keeping the camera still. But, I was also worried about startling it. So, I forced myself to calm down. That experience is difficult to describe, but I am happy to have recorded it.

五色鳥表演舌上功夫 Skillful Use of the Tongue by Muller’s Barbet

科學圖說 Scientific introduction

我是住在都會公園的五色鳥。說起我的舌上功夫，可是前無古人，後無來者。清晨，我哼著愉快的樂音，尋找今天的食物，好好飽餐一頓。飽滿的果實，填滿我的肚皮，撫慰我的心靈。吃飽喝足的我，好開心，就把果實當玩具，轉轉它，練練舌上功夫吧！瞧瞧我，是不是俏皮又美麗呢！

I am a Muller’s barbet (Psilopogon nuchalis) living in Taichung Metropolitan Park. There is no other bird better skilled in the use of the tongue. At dawn, I sing a happy tune as I forage for food. After I have filled up on fruits, I feel very happy. That is when I start to play with the fruits, turning them and turning them as I practice using my tongue. Look at me! Don’t I look beautiful?

凱門鱷與蚊 Caiman and Mosquitoes

科學圖說 Scientific introduction

這隻凱門鱷是2016年寒假在厄瓜多爾的亞馬遜雨林裡拍攝的。在照片中，可以看到鱷魚身上有很多蚊子，有些人可能會問：「鱷魚全身遍布堅厚的鱗甲，蚊子怎麼能穿透鱷魚的鱗甲呢？」大家可不要小看蚊子，這種蚊科昆蟲，不但能精確找到皮膚暴露、毛細血管密集的眼瞼部位，還能靠牠的刺吸式口器取食凱門鱷的血液。大自然總是這麼奇妙，鱷魚雖然能攻擊人類，但是得受蚊的折磨！這隻倒楣的鱷魚已經被群蚊圍攻了！

This Caiman crocodilus was photographed during 2016 winter break in the Amazon rainforest of Ecuador. In this photograph, a caiman is covered in mosquitoes. Some people may ask, “How can a mosquito penetrate a caiman’s hard, thick scales?” Do not underestimate the mosquito. These insects of the Family Culicidae can find areas of exposed skin where capillaries are concentrated, such as the eyelids, then use their piercing- sucking mouthparts to obtain blood. Nature is really amazing. Although caimans can attack humans, they also have to deal with being tortured by black flies, such as this unfortunate individual.

2015.04.04月全食 2015.04.04 Total Lunar Eclipse

科學圖說 Scientific introduction

2015年4月4日月全食過程，18:15初虧，19:54食既，20:00食甚，20:06生光，21:45復圓，臺灣全程可見。月全食發生的時機正逢滿月，月球進入地球的本影區，而使亮面被遮掩造成虧食。在全食階段，因太陽光透過地球大氣層的折射與散射，可見進入地球本影區的月亮呈現暗紅色。整個過程十分精彩，以肉眼即可窺見天地之奧秘，為容易觀察的天象之一。本作品分別以廣角鏡頭和長鏡頭記錄月全食的連續變化，以及月球通過地球的本影。

A total lunar eclipse occurred on April 4, 2015. First contact was at 6:15 pm; second contact at 7:54 pm; third contact at 8:00 pm; greatest eclipse at 8:06 pm and fourth contact at 9:45 pm. This lunar eclipse could be viewed all around Taiwan. A total lunar eclipse only occurs when a full moon enters the earth’s umbra (shadow). During the total eclipse phase, due to the refraction and scattering of the sunlight through the earth’s atmosphere, the moon appears red. The entire process is spectacular. It is one of the astronomical phenomena that is relatively easy to see with the naked eye. These images of the successive changes during a total lunar eclipse were obtained with wide-angle and long focus lenses.

月上梢頭 Moon Above the Branches

科學圖說 Scientific introduction

朔的前後幾天，月球的暗部被地球反射的太陽光線隱隱照亮，形成「新月抱舊月」的天文現象，又名「灰光」。灰光是一種常見的天文現象，但前景的選擇尤為重要。清華大學天文臺始建於1931年，原名氣象臺，為中國大陸重點文物的保護單位。將天文臺和「灰光」這種天文現象拍攝在一起，顯得更有意義。

The first few days after a new moon, the dark part of the moon is faintly illuminated by sunlight reflected from the earth to create the astronomical phenomenon known as “old moon in the new moon’s arms”. It is also referred to as “ashen light”. Ashen light is a common astronomical phenomenon. The Tsinghua University observatory was constructed in 1931. It was an important cultural artifact preservation unit in China. Photographing this observatory together with ashen light makes this image more meaningful.

灕江第一灣銀河拱橋 Milky Way Arc Above Lijiang First Bend

科學圖說 Scientific introduction

在城市燈光的包圍中，仰望銀河的璀璨繁星，逐漸成為都市人的奢求。灕江流域的桂林山水不僅有世界上最獨特而優美的喀斯特峰林景觀，也有著獨特別緻的夜空。當銀河狀如拱橋在「灕江第一灣」的上空慢慢升起，美景輝映襯著銀河，共同營造出了優美壯麗且難得的人間景色。

As the cities are enveloped in artificial lighting, gazing at the array of stars in the Milky Way has become a leisure pursuit. Guilin in the Lijiang Basin is not only famous for its karst peak landscapes, but also for its picturesque night views. As the band of the Milky Way, in the shape of an arc, slowly rises over Lijiang First Bend, the beautiful landscapes are illuminated, creating a majestic scene that is difficult to see anywhere else in the world.

鬼斧神工 Natural Craftsmanship

科學圖說 Scientific introduction

位於地底深處的岩層，漸漸地暴露到地表時，由於壓力減小，岩石產生了裂痕，因此岩石和空氣與水的接觸面積增加，會沿著岩石的節理進行風化作用。若水中或岩石內含有鐵的成分，在長期風化作用下，鐵質會氧化生成氧化鐵，顏色也轉為褐色或咖啡色。氧化作用越完全，風化紋的顏色也越深。加上受海水長期淘洗而剝落，地層擠壓出縱橫交錯的裂縫，便生成彷彿鬼斧神工般的奇岩異石。

When rock strata that were once deep underground are gradually exposed, the pressure decreases creating fissures. This increases the contact area of the rocks with air and water along the joint, leading to erosion. If the water or rocks contain iron, over a long period of weathering the iron oxidizes to become ferric oxide. This leads to a change in color to brown. The more complete the oxidation, the deeper are the colors of the patterns. Due to the long term effects of sea water, a network of fissures has formed along the surface creating an intricate work of natural craftsmanship.

億萬年的仰望 Looking Upon Billions of Years

科學圖說 Scientific introduction

庫車大峽谷位於新疆天山南麓的庫車縣附近，南北走向，全長5公里，最寬處53公尺，最窄處僅0.4公尺，只容1人躬身通過。億萬年的地質作用和風雨侵蝕，造就了庫車大峽谷獨特的地貌景觀。紅褐色的岩石在正午光線的照射下，顯露出獨特的魅力和神秘的氛圍。在峰迴路轉的深處，人類在自然面前顯得無比渺小，那整齊的刀刻痕跡，是大自然留下的永恆力量。

Kuqa Gorge is located near the southern foothills of Tian Shan in Kuqa County, Xinjiang. It runs north to south for five kilometers, and has a maximum width of 53 meters. At its narrowest point it is only 0.4 meters. Billions of years of geological process and erosion by wind and rain have created the unique landscapes. The gorge is at its most beautiful when the sun shines on the reddish brown rocks at high noon. Along the winding paths in the deepest part of the gorge it is easy to feel insignificant in the face of Nature. The neat cuts are evidence of the everlasting power of Nature.
