When did Orion become so flashy? This colorful rendition of part of the constellation of Orion comes from red light emitted by hydrogen and sulfur (SII), and blue-green light emitted by oxygen (OIII). Hues on the featured image were then digitally reassigned to be indicative of their elemental origins — but also striking to the human eye. The breathtaking composite was painstakingly composed from hundreds of images which took nearly 200 hours to collect. Pictured, Barnard’s Loop, across the image bottom, appears to cradle interstellar constructs including the intricate Orion Nebula seen just right of center. The Flame Nebula can also be quickly located, but it takes a careful eye to identify the slight indentation of the dark Horsehead Nebula. As to Orion’s flashiness — a leading explanation for the origin of Barnard’s Loop is a supernova blast that occurred about two million years ago. Share the Sky: NASA Open API for APOD

🪐✨ 當奧里恩變得如此光鮮奪目？這幅色彩繽紛的奧里恩星座部分影像，來自氫和硫（SII）所發出的紅光，以及氧（OIII）所散發的藍綠光。圖像中的色調經過數位重新編排，以表達其元素來源，同時對人眼也十分吸引。這幅令人驚嘆的合成圖是由數百張影像組成，採集過程耗時近200小時。
🛸 圖像底部的巴納德環（Barnard’s Loop）如同環抱著星際結構，當中包括精緻的獵戶座星雲（Orion Nebula），位於畫面中心右側。火焰星雲（Flame Nebula）也可以輕易找到，但若想辨認出微妙的馬頭星雲（Horsehead Nebula）則需要仔細觀察。
🌌 至於奧里恩的華麗外表，一個主要的解釋是巴納德環的起源可能源於約兩百萬年前發生的超新星爆炸。
