你听说过哈勃超深场吗？无论哪种方式，你可能都没有听说过这样的情况——请将光标移动到特色图像上并听！哈勃超深场（HUDF）是在2003-2004年创建的，哈勃太空望远镜长时间盯着接近空旷的空间，这样遥远的、微弱的星系就会变得可见。作为天文学中最著名的图像之一，HUDF以一种充满活力的方式呈现在这里——与声音的距离。指向一个星系会发出一个音符，表示它的近似红移。因为红移将光移向光谱的红端，所以它们在这里被描述为音调向声音光谱的低端移动。星系越远，它的宇宙学红移越大（即使它看起来是蓝色的），并且将播放的音调越低。HUDF中的平均星系距离我们约106亿光年，听起来像f#。你能找到的最远的星系是什么？

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?
