光與聲中的哈勃超深場
The Hubble Ultra Deep Field in Light and Sound

您聽說過哈勃超深視場嗎？ 無論如何，你可能都沒有聽說過這樣的事--請將游標移到特寫圖片上聽一聽！ 哈勃超深視場（HUDF）產生於 2003 - 2004 年，當時哈勃太空望遠鏡長時間注視著近乎空曠的太空，這樣就能看到遙遠而模糊的星系。 作為天文學中最著名的影像之一，HUDF 在這裡以一種生動的方式呈現--用聲波顯示距離。指向一個星系，就會播放出一個音符，顯示其大致的紅移。由於紅移使光向光譜的紅色一端移動，因此這裡用音調向聲音譜的低端移動來描述紅移。 星系越遠，其宇宙學紅移越大（即使它看起來是藍色的），播放的音調也就越低。HUDF 中的星系平均距離約為 106 億光年，聽起來像F#音。你能找到的最遙遠的星系是什麼？
原文：Have you heard about the Hubble Ultra-Deep Field? Either way, you've likely not heard about it like this -- please run your cursor over the featured image and listen! The Hubble Ultra-Deep Field (HUDF) was created in 2003-2004 with the Hubble Space Telescope staring for a long time toward near-empty space so that distant, faint galaxies would become visible. One of the most famous images in astronomy, the HUDF is featured here in a vibrant way -- with sonified distances. Pointing to a galaxy will play a note that indicates its approximate redshift. Because redshifts shift light toward the red end of the spectrum of light, they are depicted here by a shift of tone toward the low end of the spectrum of sound. The further the galaxy, the greater its cosmological redshift (even if it appears blue), and the lower the tone that will be played. The average galaxy in the HUDF is about 10.6 billion light years away and sounds like an F#. What's the most distant galaxy you can find?
