NGC 602 及其周邊
NGC 602 and Beyond

發表日期:2026-04-13
這些星雲看似牡蠣,其中的恆星宛如珍珠,但請看更深處。在小麥哲倫雲的邊緣附近——這是一個距離我們約 20 萬光年的衛星星系——坐落著一個僅有 500 萬年曆史的年輕星團NGC 602 。在這張哈勃望遠鏡拍攝的該區域的驚豔影像中,NGC 602 被其誕生的氣體和塵埃所環繞。 那些奇幻的山脊和向後掃掠的形狀強烈暗示,NGC 602 中那些質量巨大的年輕恆星所釋放的高能輻射和衝擊波,侵蝕了塵埃物質,並引發了一系列從星團中心向外擴散的恆星形成過程。以小麥哲倫星雲的估計距離計算,這張特寫圖片的範圍約為 200 光年,但在這張清晰多彩的影像中,還能看到一組引人入勝的背景星系。 這些背景星系位於NGC 602 之外數億光年甚至更遠的地方。 星空驚喜:美聯社每日一圖(APOD)在你生日那天刊登了哪張圖片?( 1995 年以後)
原文:The clouds may look like an oyster, and the stars like pearls, but look beyond. Near the outskirts of the Small Magellanic Cloud, a satellite galaxy some 200 thousand light-years distant, lies 5 million year young star cluster NGC 602. Surrounded by natal gas and dust, NGC 602 is featured in this stunning Hubble image of the region. Fantastic ridges and swept back shapes strongly suggest that energetic radiation and shock waves from NGC 602's massive young stars have eroded the dusty material and triggered a progression of star formation moving away from the cluster's center. At the estimated distance of the Small Magellanic Cloud, the featured picture spans about 200 light-years, but a tantalizing assortment of background galaxies are also visible in this sharp multi-colored view. The background galaxies are hundreds of millions of light-years or more beyond NGC 602. Sky Surprise: What picture did APOD feature on your birthday? (after 1995)
