This telescopic close-up shows off the otherwise faint emission nebula IC 410. It also features two remarkable inhabitants of the cosmic pond of gas and dust below and right of center, 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. 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 winds and radiation from the cluster stars, their heads are outlined by bright ridges of ionized gas while their tails trail away from the cluster’s central region. IC 410 lies some 10,000 light-years away, toward the nebula-rich constellation Auriga.

這張透視特寫圖展示了IC 410這個在一般情況下較為微弱的發射星雲。下方和右側中央的宇宙氣體和塵埃池中，還有兩個引人注意的居民：IC 410的“蝌蚪”。星雲本身被前景的塵埃部分遮掩，周圍環繞著年輕的星團NGC 1893。這個星團於約400萬年前在星際雲中形成，熾熱而明亮的星團星星為周圍的氣體帶來能量，使其發光。這些“蝌蚪”由較為密集的冷氣體和塵埃組成，長約10光年，是可能的恆星形成地點。在星團星星的風和輻射影響下，它們的頭部被輝亮的電離氣體輪廓勾勒，而尾部則朝向星團中央的區域延伸。IC 410距離地球約10,000光年，位於富含星雲的星座——金猴座（Auriga）。
