Massive star IRS 4 is beginning to spread its wings. Born only about 100,000 years ago, material streaming out from this newborn star has formed the nebula dubbed Sharpless 2-106 Nebula (S106), featured here. A large disk of dust and gas orbiting Infrared Source 4 (IRS 4), visible in brown near the image center, gives the nebula an hourglass or butterfly shape. S106 gas near IRS 4 acts as an emission nebula as it emits light after being ionized, while dust far from IRS 4 reflects light from the central star and so acts as a reflection nebula. Detailed inspection of a recent infrared image of S106 reveal hundreds of low-mass brown dwarf stars lurking in the nebula’s gas. S106 spans about 2 light-years and lies about 2000 light-years away toward the constellation of the Swan (Cygnus).

🌌 大質量恆星 IRS 4 正在展開它的翅膀。這顆恆星誕生於約 100,000 年前，從它身上流出的物質形成了這個被稱為 Sharpless 2-106 Nebula (S106) 的星雲。位於圖像中央的棕色區域是環繞著紅外源 4 (IRS 4) 的大片塵埃和氣體圓盤，讓星雲呈現出沙漏或蝴蝶的形狀。S106 中靠近 IRS 4 的氣體作為發射星雲，在被電離後發出光線，而遠離 IRS 4 的塵埃則反射來自中央恆星的光，故而形成反射星雲。對 S106 最近的紅外圖像進行詳細檢查，發現了數百顆隱藏在星雲氣體中的低質量棕矮星。S106 的大小約為 2 光年，距離我們約 2000 光年，位於天鵝座 (Cygnus) 的方向。
