這幅宇宙景象展示的是一個暗淡的發射星雲 IC 410 ,是在荷蘭晴朗的天空下用望遠鏡和窄帶濾光片拍攝的。在上方和中間偏右的位置,你可以看到星際氣體和塵埃池中的兩個非凡居民,它們被稱為 IC 410 的蝌蚪。部分星雲被前景塵埃遮擋,星雲本身圍繞著 NGC 1893 ,這是一個由恆星組成的年輕星系團。這個星團形成於僅僅 400 萬年前的星際雲中,熾熱明亮的星團恆星為熾熱的氣體提供了能量。蝌蚪由密度較高的冷氣體和塵埃組成,長約 10 光年,很可能是恆星正在形成的地方。在恆星風和輻射的作用下,它們的頭部被電離氣體的亮脊勾勒出來,而尾部則遠離星團中央的年輕恆星。IC 410 和內含的 NGC 1893 位於大約 10 , 000 光年之外,朝向星雲豐富的御夫座。
原文:This cosmic view shows off an otherwise faint emission nebula IC 410, captured under clear Netherlands skies with telescope and narrowband filters. Above and right of center you can spot two remarkable inhabitants of the interstellar pond of gas and dust, known as the tadpoles of IC 410. Partly obscured by foreground dust, the nebula itself surrounds NGC 1893, a young galactic cluster of stars. Formed in the interstellar cloud a mere 4 million years ago, the intensely hot, bright cluster stars energize the glowing gas. Globules composed of denser cooler gas and dust, the tadpoles are around 10 light-years long and are likely sites of ongoing star formation. Sculpted by stellar winds and radiation their heads are outlined by bright ridges of ionized gas while their tails trail away from the cluster's central young stars. IC 410 and embedded NGC 1893 lie some 10,000 light-years away, toward the nebula-rich constellation Auriga.
