什麼時候能同時看到黑洞、鬱金香和天鵝?在夜晚--如果時機合適,如果你的望遠鏡指向正確的方向。 複雜而美麗的鬱金香星雲在大約 8000 光年外的天鵝座綻放。 來自天鵝座OB 3 星團邊緣的年輕高能恆星(包括O 型星HDE 227018 )的紫外線輻射使原子電離,併為鬱金香星雲的發射提供了能量。 斯圖爾特-夏普萊斯(Stewart Sharpless)於 1959 年將這個直徑近 70 光年的星際氣體和塵埃紅色發光雲團編入 Sh 2 - 101 星系。天鵝座 X- 1 黑洞也出現在特寫視場中,由於它是地球天空中最強的 X 射線源之一,因此被稱為微類星體。天鵝座 X- 1 被潛伏黑洞的強大噴流噴射,其較暗的藍色彎曲衝擊波前沿只能在宇宙鬱金香花瓣外隱約可見,靠近畫面右側。 回到學校?與 NASA 一起學習科學
原文:When can you see a black hole, a tulip, and a swan all at once? At night -- if the timing is right, and if your telescope is pointed in the right direction. The complex and beautiful Tulip Nebula blossoms about 8,000 light-years away toward the constellation of Cygnus the Swan. Ultraviolet radiation from young energetic stars at the edge of the Cygnus OB3 association, including O star HDE 227018, ionizes the atoms and powers the emission from the Tulip Nebula. Stewart Sharpless cataloged this nearly 70 light-years across reddish glowing cloud of interstellar gas and dust in 1959, as Sh2-101. Also in the featured field of view is the black hole Cygnus X-1, which to be a microquasar because it is one of strongest X-ray sources in planet Earth's sky. Blasted by powerful jets from a lurking black hole, its fainter bluish curved shock front is only faintly visible beyond the cosmic Tulip's petals, near the right side of the frame. Back to School?
