トランスメディア提供アイコン01 利用哈伯窺探宇宙的氣泡



I discovered the above photo taken by Hubble on a blog this morning. If you are interested to know more about this nebula in english, please click the following link to hubblesite.
Hubble Peers Inside a Celestial Geode

今早在一個網頁(ハッブルで宇宙の泡の内部を見つめると)上發現了上面的相片。相片由哈伯望遠鏡拍下,名為「利用哈伯窺探宇宙的氣泡」。

Geode(氣泡?)一字在地質學上是指在火山或沉積岩中形成像棒球般大的中空氣殼。要把氣泡切開後才能欣賞到內部的水晶.


但這個宇宙中的氣泡是透明的,充滿了氣體。我們不必切開它就觀察到內部新生的恆星,和恆星所射出的強烈氣紫外線和氣流。氣泡的直徑是35光年。中間的星體名為「N44F」。位於南半球的大麥哲倫星雲(N44)之中。離銀河系16萬光年,是銀河的彼鄰。有興趣的話,網上還有更多的資料喔。

トランスメディア提供アイコン01 少年的銀河

衝突する錯覚をもたらすような2つの渦状銀河

The photo has recalled a lot of memory.

Many years ago, I have seen this photo in a science magazine. The title of the article is "The Crashing Universe". NGC3314 is a member of Hydra I cluster. These two galaxies look like colliding, but they are far apart and lining-up back and fore according to our position. Nevertheless, it is gorgeous.



Because of the reminiscence of my passion to the universe in my childhood, I clicked on an ad introducing a blog of images of universe and saw this photos again. Being an astronomer was my first dream. Before the graduation from elementary school, I kept reading books about this tropic painfully. Books about astronomy can be very difficult to understand, it was painful to read them. The last book of this field which I read before the end of Grade 6 is titled "Black Hole". Including over one hundred pages, termless appearance of new terms, concept of the Relativity theory. It took me a long time to reach the final chapter, but I still terminated the reading exercise when there were only a few more pages to go.

a0003697_1611691.jpgThree days ago, I gladly received an email from my dear buddy in Los Angeles. He sent me an image of a telescope of his own design and craftsmenship. It can be collapsed to a compact form to put in a small car for travelling. Brilliant. I'm so pround of him. He wants to take it to competition too. I tried to make one when I was in high school, but I didn't complete it. However my home in Hong Kong is too small, I had to trash it even if I finished it.

I also dicovered a photo of real collision between galaxies today. They are NGC2207 and IC2163 of Canis Major. Magnificent. This one was also taken with the Hubble.
