原文:
NGC 1333 is seen in visible light as a reflection nebula, dominated by bluish hues characteristic of starlight reflected by interstellar dust. A mere 1,000 light-years distant toward the heroic constellation Perseus, it lies at the edge of a large, star-forming molecular cloud. This striking close-up spans about two full moons on the sky or just over 15 light-years at the estimated distance of NGC 1333. It shows details of the dusty region along with hints of contrasting red emission from Herbig-Haro objects, jets and shocked glowing gas emanating from recently formed stars. In fact, NGC 1333 contains hundreds of stars less than a million years old, most still hidden from optical telescopes by the pervasive stardust. The chaotic environment may be similar to one in which our own Sun formed over 4.5 billion years ago.

🌌 NGC 1333 是一個反射星雲,以藍色的色調為主,這些色調是星光反射在星際塵埃上的結果。這個星雲距離我們約 1,000 光年,位於英俊的仙女座星座,正好坐落於一個大型星際分子雲的邊緣。這個驚人的特寫圖像大約占據了天空中兩個滿月的範圍,或在估計距離 NGC 1333 約 15 光年。它展示了多塊含有塵埃的區域的細節,並夾雜著來自 Herbig-Haro 天體的紅色發射,這些是來自剛出生的恆星的噴流和激波發光的氣體。事實上,NGC 1333 中包含了數以百計的誕生不久的恆星,絕大多數仍然被周圍的星塵遮擋,無法用光學望遠鏡觀察。這樣混亂的環境可能類似於我們的太陽在超過 45 億年前形成時的情況。
