Often imaged but rarely mentioned, Messier 43 is a large star forming region in its own right. It’s just part of the star forming complex of gas and dust that includes the larger, more famous neighboring Messier 42, the Great Orion Nebula. In fact, the Great Orion Nebula itself lies off the lower edge of this scene. The close-up of Messier 43 was made while testing the capabilities of a near-infrared instrument with one of the twin 6.5 meter Magellan telescopes at Las Campanas Observatory in the Chilean Andes. The composite image shifts the otherwise invisible infrared wavelengths to blue, green, and red colors. Peering into caverns of interstellar dust hidden from visible light, the near-infrared view can also be used to study cool, brown dwarf stars in the complex region. Along with its celebrity neighbor, Messier 43 lies about 1,500 light-years away, at the edge of Orion’s giant molecular cloud. At that distance, this field of view spans about 5 light-years.

🌌【探索梅西耶43 (Messier 43)】🌌
雖然經常被拍攝，但卻很少被提及，梅西耶43 是一個大型的恆星形成區。它僅僅是星際氣體和塵埃中的一部分，與鄰近的更著名的梅西耶42（大獵戶星雲）共同組成了一個恆星形成複合體。實際上，大獵戶星雲本身就在這幅影像的下方。這張梅西耶43 的特寫圖像是在智利安第斯山脈的拉斯坎帕納斯天文台（Las Campanas Observatory）對雙6.5米馬卡連望遠鏡進行近紅外線儀器性能測試時拍攝的。
這幅合成圖像將原本不可見的紅外波長轉換為藍色、綠色和紅色。借助近紅外線的視角，我們可以深入觀察隱藏在可見光之外的星際塵埃洞穴，並研究這個複合區域中的冷棕矮星。梅西耶43，連同它的名氣鄰居，距離我們約1,500光年，位於獵戶座巨分子雲的邊緣。這個視野的範圍約為5光年。
