喺獵戶座大星雲 (Orion Nebula) 充滿 intrigue。用裸眼望去，佢只係一個細細嘅模糊斑點，但呢幅圖係透過地球軌道嘅WISE太空望遠鏡，用唔同波段嘅紅外線光拍攝嘅四面馬賽克，展示咗獵戶座大星雲其實係一個充滿活力嘅新星區域，佢包括咗新形成嘅恆星、炎熱嘅氣體同埋黑暗嘅塵埃。位於圖像中心附近嘅梯形星團 (Trapezium star cluster) 為獵戶座大星雲 (M42) 提供咗巨大能量，呢啲明亮恆星周圍嘅橙色光輝正係佢哋自己嘅星光，反射咗周圍複雜嘅塵埃絲線。現時嘅獵戶座大星雲雲複合體，包括咗馬頭星雲 (Horsehead Nebula)，會喺未來十萬年內慢慢散開。

原文:
The Great Nebula in Orion is an intriguing place. Visible to the unaided eye, it appears as a small fuzzy patch in the constellation of Orion. But this image, an illusory-color four-panel mosaic taken in different bands of infrared light with the Earth orbiting WISE observatory, shows the Orion Nebula to be a bustling neighborhood of recently formed stars, hot gas, and dark dust. The power behind much of the Orion Nebula (M42) is the stars of the Trapezium star cluster, seen near the center of the above wide field image. The orange glow surrounding the bright stars pictured here is their own starlight reflected by intricate dust filaments that cover much of the region. The current Orion Nebula cloud complex, which includes the Horsehead Nebula, will slowly disperse over the next 100,000 years. Now Available: APOD 2015 Wall Calendars
